Elastic Services Controller Overview
Cisco Elastic Services Controller (ESC) is a Virtual Network Functions Manager (VNFM), which performs life cycle management of Virtual Network Functions (VNFs). ESC provides agent-less and multi vendor VNF management by provisioning virtual services, and monitoring their health and load. ESC provides the flexibility to define monitoring rules, and associate actions to be triggered based on the outcome of these rules. As a
VNFM, in addition to the typical lifecycle management operations, ESC also supports automatic VM recovery when a VM fails and performs automatic scaling in and out functions. ESC fully integrates with Cisco and other third party applications.
• As part of the Cisco Orchestration Suite, ESC is packaged with Cisco Network Services Orchestrator
(NSO), and available within Cisco Solution, Managed Services Accelerator Solution (MSX).
• As a Specialized Virtual Network Function Manager (SVNFM), ESC tightly integrates with the Cisco
Mobility VNFs.
• ESC can also be utilized as a Generic Virtual Network Function Manager (GVNFM) to provide lifecycle management for both Cisco and third-party VNFs.
ESC is deployed in a virtual machine within OpenStack, VMware vCenter, KVM or AWS and manages its
VNFs in a Virtual Infrastructure Manager (VIM).
Elastic Services Controller as a VNF Manager targets the virtually managed services and all service provider
NFV deployments such as virtual video, WiFi, authentication and others.
Cisco Elastic Services Controller 5.3 Install and Upgrade Guide

Elastic Services Controller Overview
Elastic Services Controller Overview
ESC can manage both basic and complex VNFs . Basic VNFs include a single VM such as a vFW, vRouter and others.
Complex VNFs include multiple VMs that are orchestrated as a single entity with dependencies between them.
IPv6 Support
Elastic Services Controller provides IPv6 support on OpenStack for:
• VNF Management
• HA— ESC manages VNFs on IPv4 and IPv6 (OpenStack and KVM only).
Elastic Services Controller provides IPv6 support for northbound interface (for example, NFVO to VNFM), and southbound interface (for example, VNFM to VNF). In order to support both northbound and southbound
IPv6 concurrently, the following pre-requisites must be met:
• OpenStack cloud computing is set up and configured for ipv6, including the endpoints (that are ipv6 based).
• The OpenStack cloud computing must contain a Controller, endpoints, and a few Compute hosts, with an ipv6 management and os_api based networks.
• The ESC default security group rules support the IPv6 traffic.
Note When you are deploying a VM, you can attach an out-of-band port of an IPv6 subnet to a VM. However, if you are deleting this VM, you cannot attach the same IPv6 address to another VM due to a known OpenStack issue.

Installation Scenarios
The following sections briefly describe some of the common deployment scenarios that are addressed by ESC.
Cisco Elastic Services Controller can be installed in different modes as per the requirement. These different modes are configured during installation. The following sections briefly describe some of the common deployment scenarios that are addressed by ESC.
ESC Standalone
In the standalone scenario, a single active VM is deployed for ESC.
ESC with HA
ESC supports High Availability (HA) in the form of Active/Standby and Active/Active models. For
Active/Standby model, two ESC instances are deployed in the network to prevent ESC failure and to provide
ESC service with minimum interruption. If the primary ESC instance fails, the standby instance automatically takes over the ESC services. ESC HA resolves the following single point failures of ESC:
• Network failures
• Power failures
• Dead VM instance
• Scheduled downtime

• Hardware issues
• Internal application failures
Note From ESC 5.0, the name, Active/Passive model is changed to Active/Standby model.
Note Installing or upgrading software on the ESC VM is not supported. For further assistance, contact Cisco TAC.
For more information on deploying ESC HA Active/Standby, see 'Configuring High-Availability
Active/Standby' in Installing ESC on OpenStack and Installing ESC on VMware chapters.
For more information on the Active/Active model, see ESC HA Active/Active Overview Chapter.
Main Components of Cisco Elastic Services Controller Setup
The Cisco Elastic Service Controller (ESC) setup has the following components:
• Virtual Infrastructure Manager —Elastic Services Controller (ESC) and its VNFs are deployed in a
Virtual Infrastructure Manager (VIM). This might have one or more underlying physical nodes.
• ESC Virtual Machine —The ESC VM is a VM that contains all the services and processes used to register and deploy services. This includes the ESC Manager and all other services. ESC provides Netconf
API, REST API, and Portal as north bound interfaces to communicate with ESC. ESC VM contains CLI to interact with ESC VM. There are two CLI, one uses the REST API and the other uses Netconf API.
Installing Cisco Elastic Services Controller Using the QCOW
Image
You can install Cisco Elastic Services Controller (ESC) on OpenStack by using a QCOW image. ESC will be deployed in the OpenStack as running VM instance to manage VNFs. Therefore, ESC need OpenStack environment parameters to be installed in OpenStack. The installation time varies from 10 to 20 minutes, depending on the host and the storage area network load. This procedure describes how to create ESC Virtual
Machine (VM) in OpenStack.
Before you begin
• All system requirements are met as specified in
.
• You have the information identified in
Preparing for the Installation, on page 6 .
• Copy the ESC image file on the system where you want to install ESC.
• This system must be accessible by OpenStack.

Cisco Elastic Services Controller 5.3 Install and Upgrade Guide
Installing Cisco Elastic Services Controller on OpenStack
Installing Cisco Elastic Services Controller Using the QCOW Image
Procedure
Step 1
Step 2
Step 3
Log in to the system where you want to install ESC.
Check the compatibility of the bootvm.py and the ESC image:
./bootvm.py --version
For more information on the ESC installer arguments, see Appendix: A Cisco Elastic Services Controller
Installer Arguments .
In a text editor, create a file named PROJECT-openrc.sh file and add the following authentication information.
The following example shows the information for a project called admin, where the OpenStack username is also admin, and the identity host is located at controller node.
Note To set the required environment variables for the OpenStack command-line clients, you must create an environment file called an OpenStack rc file, or openrc.sh file. This project-specific environment file contains the credentials that all OpenStack services use. The ESC installation script requires these OpenStack environment parameters to perform authentication and installation on OpenStack.
If all the OpenStack credentials are passed through its own arguments, the bootvm.py script doesn't require these parameters.
Step 4
Step 5 export OS_NO_CACHE=true export OS_TENANT_NAME=admin export OS_USERNAME=admin export OS_PASSWORD=admin_pass export OS_AUTH_URL= http://controller node:35357/v2.0
The other OpenStack parameters required for installation are: --os_auth_url, --os_username, --os_password
, -os_tenant_name, --bs_os_user_domain_name, --bs_os_project_domain_name, --bs_os_identity_api_version,
--bs_os_auth_url, --bs_os_username, --bs_os_password , -bs_os_tenant_name, --bs_os_user_domain_name,
--bs_os_project_domain_name, --bs_os_identity_api_version.
For OpenStack V2 API, you need following items to be defined in your global environment variables:
--os_password, --os_auth_url, --os_username, --os_tenant_name.
For OpenStack V3 API, set --os_identity_api_version=3 . Other parameters required for OpenStack V3 API are: --os_user_domain_name, --os_project_domain_name, --os_project_name, --os_password, --os_auth_url,
--os_username, --os_identity_api_version, --os_ca_cert, --requests_ ca_bundle.
Note The arguments, --os_tenant_name, --os_username, --os_password, --os_auth_url will also by default configure the VIM connector. If you want to skip configuring the VIM connector, pass the parameter
(--no_vim_credentials) with the bootvm.py. When no_vim_credentials parameter is provided, the bootvm.py arguments (os_tenant_name, os_username, os_password,os_auth_url) are ignored. For more information on configuring VIM connectors after installation, and managing VIM connectors, see Managing VIM Connectors in the Cisco Elastic Services Controller User Guide .
Note --os_ca_cert and --requests_ca_bundle arguments are only required for https connection.
On any shell from which you want to run OpenStack commands, source the PROJECT-openrc.sh
file for the respective project. In this example, you source the admin-openrc.sh
file for the admin project .
$ source admin-openrc.sh
Check the environment variables.

--name esc-1_0_01_11_2011-01-01 \
--is-public=<true or false> or --visibility public or private \
--disk-format qcow2 \
--container-format bare \
--file esc-1_0_01_11_2011-01-01.qcow2 \
--progress
The glance image-create command is used to create a new image. The command takes the following arguments:
Note The 'is-public' argument is applicable only for OpenStack Kilo release.
Arguments name is-public disk-format container-format file progress
Description
Name of the image.
(Optional) Makes the image accessible to the public.
Disk format of the image. ESC uses a qcow2 disk format.
Container format of image. ESC uses a bare container format.
Local file that contains disk image to be uploaded during creation.
(Optional) Shows upload progress bar.
To verify whether the image has been registered successfully: a) Using OpenStack Controller dashboard:
• Log into OpenStack using your credentials.
• Navigate to Admin > Image .
Verify if the image appears in the list.
b) Using nova CLI:
$ nova image-show <image_name>
The standard resource requirement of ESC is 4vCPU, 8G RAM, and 40GB disk space. ESC installation script takes the pre-defined "m1.large" flavor which has the definition of 4vCPU, 8G RAM and 80G disk space. To use 40GB disk space, create a flavor with the minimum disk space requirement.
$ nova flavor-create ESC_FLAVOR_NAME ESC_FLAVOR_ID 8192 40 4
To deploy ESC VM, do the following:

Additional Installation Options a.
Ensure that the existing network have connectivity to OpenStack controller. To verify the network connectivity using the nova CLI use:
$ nova net-list b.
Record the ID of the network that ESC connects to boot the ESC VM by with image and flavor created earlier. The bootvm.py command requires at least one --user_pass argument to create an admin account for linux (ssh/console access) and at least one --user_confd_pass to create an admin account for ConfD
(netconf/cli access). The following are the syntax for these mandatory user credential arguments:
--user_pass admin:'PASSWORD-OR-HASH'[:OPTIONAL-PUBLIC-KEY-FILE][:OPTIONAL-ROLE]
--user_confd_pass admin:'PASSWORD-OR-HASH'[:OPTIONAL-PUBLIC-KEY-FILE]
Generating hashed password is optional. You can select a plain password as and when required.
To generate a hashed password on Ubuntu OS, use the following command: mkpasswd --method=SHA-512 --salt XyZ123 <<< <Password>
The following is an example to install ESC with an authorized public key. In the following example, single quotes are used to avoid conflict with shell reserved characters:
--user_pass admin:'$algorithm$salt$hash-of-salt-password':$HOME/.ssh/esc_rsa.pub
--user_confd_pass admin:'$algorithm$salt$hash-of-salt-password':$HOME/.ssh/esc_rsa.pub
The public key are generated as part of a key pair with, such as: ssh-keygen -t rsa -b 1024 -C "esc" -N "" -f ~/.ssh/esc_rsa
Your public key and identification key are saved in /home/username /.ssh/esc_rsa and esc_rsa.pub files.
For more examples on the user credential arguments, see Appendix A: Cisco Elastic Services Controller
Installer Arguments.

To check the details of ESC VM and get the information including the IP address(es) of the ESC VM, use the following command:
$ nova show <esc_vm_name>
Additional Installation Options
• Deploying ESC in an OpenStack IPv6 environment: Before deploying ESC instance in IPv6, make sure to source openrc that supports ipv6 addresses. To deploy ESC in IPv6 environment, use the following bootvm arguments:
./bootvm.py
<esc_vm_name-ipv6> --poll --user_rest_pass <username> : <password> --image
<image_name>
--net <ipv6_network> --ipaddr <ipv6_ip_address> --enable-http-rest --user_pass
<username> : <password>
--user_confd_pass <username> : <password> --etc_hosts_file <hosts-file-name> --route
<default routing configuration>
• Deploying ESC in DHCP mode: If you use the bootvm.py argument without --ipaddr, then the ESC instance will be deployed in a DHCP mode. To deploy ESC in a DHCP network, use the following configuration:
Cisco Elastic Services Controller 5.3 Install and Upgrade Guide
11
Installing Cisco Elastic Services Controller on OpenStack
Additional Installation Options
./bootvm.py
<esc_vm_name> --image <image_name> --net <IPv6 network> <IPv4 network>
--flavor <flavor_name>
--user_pass <username> : <password>
--user_confd_pass <username> : <password>
Note By default, ESC only support DHCP in IPv4 networks. If IPv6 is used, you need to log in the ESC VM and run "dhclient -6 ethX" (ethX is the V6 interface name) manually to enable V6 DHCP.
When deploying ESC with multiple network interfaces, with one or more type of DHCP, use bootvm.py --defroute N to specify the interface index to be assigned default route and gateway IP.
By default,
N = 0
. So the first network interface on the bootvm.py
command line is default.
For Example:
--defroute 1 will assign <network2> with <default_gateway_ip_address>
./bootvm.py <esc_vm_name> --image <image_id> --net <network1>
<network2> --defroute 1 --gateway_ip <default_gateway_ip_address>
• Using a Bootable Volume in ESC Installation: You can attach a volume to an ESC instance and launch an instance from inside the volume. For more information, see the section
• Assigning Floating IP to the ESC: If you want to associate a floating IP with the ESC instance , do the following:
1.
Check for an available floating IP address and assign it to the ESC VM:
$ nova floating-ip-list
$ nova floating-ip-associate esc_vm_name <ip_address>
2.
Or create a new floating IP address and assign it to the ESC VM:
$ nova floating-ip-create <FLOATING_NETWORK - ID>
$ nova floating-ip-associate esc_vm_name <ip_address> or neutron floatingip-create FLOATING_NETWORK neutron floatingip-associate floating-ip-ID port-ID
• Deploying ESC with static IPs: To use ESC in a specific network with static IPs, for example,
192.168.0.112 at network1, specify --ipaddr and --gateway_ip to the bootvm command line , as shown below:
Note Before assigning static IP, make sure the static IP is available and is not being used on other machine.
./bootvm.py
<esc_vm_name> --image <image_id> --net <network>
--ipaddr <ip_address> --gateway_ip <default_gateway_ip_address> --user_pass
<username> : <password>
--user_confd_pass <username> : <password>

• Deploying ESC with multiple network interfaces: To use multiple networks for ESC, for example,
192.168.0.112 at network1 and 10.20.0.112 at network2, specify both the IP addresses and the network names of the interfaces in the --net and --ipaddr arguments in the following command line. In addition, also choose the default gateway for ESC from the gateways of these networks. Specify the default gateway for ESC through the --gateway_ip argument.
./bootvm.py
<esc_vm_name> --image <image_id> --net <network1>
<network2> --ipaddr <ip_address1> <ip_address2> --gateway_ip <default_gateway_ip_address>
--user_pass <username> : <password>
--user_confd_pass <username> : <password>
Note If --flavor is not specified, bootvm.py will use the default flavor "m1.large" in
OpenStack.
Ensure that m1.large exist in OpenStack if decide not specified a flavor, and also ensure that the flavor suits ESC deployment requirement.
• Deploy ESC with log forwarding options: To forward ESC logs to an rsyslog server, specify the IP address of the rsyslog server while creating an ESC VM. Optionally, you can also specify the port and protocol to use.
For example, if the IP address of the rsyslog server is 172.16.0.0 the port on the server to forward logs is 514, and the protocol used is UDP, the ESC installation could be
./bootvm.py
<esc_vm_name> --image <image_id> --net network1 --rsyslog_server 172.16.0.0
--rsyslog_server_port 514 --rsyslog_server_protocol udp --user_pass <username> : <password>
--user_confd_pass <username> : <password>
• Disabling the ESC GUI: To boot up ESC VM with the graphical user interface disabled, modify the
--esc_ui_startup argument value, as shown in the command line below:
./bootvm.py
<esc_vm_name> --image <image_id> --net <network> --user_pass
<username> : <password>
--user_confd_pass <username> : <password>
--esc_portal_startup=False
• Enabling REST interface for ESC: To support the REST interface, specify --enable-https-rest argument.
You can activate REST interface on both https or http:
./bootvm.py
<esc_vm_name> --image <image_id> --net <network> --user_pass
<username> : <password>
--user_confd_pass <username> : <password> --enable-https-rest

Note Only the https REST and ETSI interfaces should be enabled in a production environment.
• Deploying ESC with global parameters: To set the global configurations through the esc_params_file during the installation, use the arguments as shown below. These global configurations can also be changed through REST API after the installation.
Note The default security group is applied to the tenant during tenant creation. By default, the ESC configuration parameter for the security group, openstack.DEFAULT_SECURITY_GROUP_TO_TENANT
is set to true. The configuration parameter must be set at the time of installation. You can query or update the parameter on ESC VM through the REST API. If the parameter is set to true, you can create and assign default security group during tenant creation.
If the parameter is set to false, you cannot create or assign default security group during tenant creation. For details on the parameters that can be configured through esc_params_file, see Appendix A: Cisco Elastic Services Controller Installer
Arguments.

• Deploying two instances of ESC to build an ESC HA (Active/Standby) pair : For more information on deploying ESC HA (Active/Standby), see Configuring High Availability in Installing ESC on
OpenStack and Installing ESC on VMware chapters.
• Adding a Dynamic Mapping File : In Cisco ESC Release 2.1 and earlier, mapping the actions and metrics defined in the datamodel to the valid actions and metrics available in the monitoring agent was enabled using the dynamic_mappings.xml
file. The file was stored in the ESC VM and was modified using a text editor. ESC 2.2 and later do not have an esc-dynamic-mapping directory and dynamic_mappings.xml
file. If you want to add an existing dynamic_mapping xml file to the ESC VM, do the following:
1.
Backup this file to a location outside of ESC, such as, your home directory.
2.
Create esc-dynamic-mapping directory on your ESC VM. Ensure that the read permissions are set.
3.
Install on your ESC VM using the following bootvm argument:
--file root:root: /opt/cisco/esc/esc-dynamic-mapping/dynamic_mappings.xml
:< path-to-local-copy-of-dynamic-mapping.xml
>
The CRUD operations for mapping the actions and the metrics is available through REST API. To update an existing mapping, delete and add a new mapping through the REST API.

Managing Root Certificates in Cisco Elastic Services Controller
• Changing the confd password on an ESC VM : As an administrator, you can configure the confd password through bootvm.py, during the installation time:
./bootvm.py --user_pass <username> : <password> --user_confd_pass admin:'PASSWORD-OR-HASH':OPTIONAL-PUBLIC-KEY
To reconfigure this password after the installation, execute the following commands:
$ /opt/cisco/esc/confd/bin/confd_cli -u admin
$ configure
$ set aaa authentication users user admin password <your_password>
$ commit
$ exit
Note For the ease of future upgrades, make sure that you keep a copy of all the commands and arguments that are used while installing ESC using the bootvm.py file.
Managing Root Certificates in Cisco Elastic Services Controller
Cisco Elastic Services Controller (ESC) provides a mechanism to enable verification of SSL certificates.
Currently, this feature is supported only on OpenStack. Certificate validation is enabled by default during the initial ESC boot up. However, ESC also allows you to configure these SSL certificates. This section describes how to enable/disable certificate validation, add/remove, or list the certificates for Cisco Elastic Service
Controller on OpenStack. You can add a root certificate during the ESC bootup or even after ESC bootup is completed.
Enabling/Disabling the Root Certificate Validation
Cisco Elastic Services Controller by default enables certificate validation. You can also enable or disable by modifying the parameter, DISABLE_CERT_VALIDATION, available under the Openstack category in the esc_params.conf file, or through the REST interface, or using the escadm tool.
On ESC master node, use the command, sudo escadm enable-certificate or sudo escadm disable-certificate to enable and disable the certificate validation, respectively.
Adding a Root Certificate
You can add a root certificate during the ESC bootup or even after ESC bootup is completed. Before adding certificates, ensure the OpenStack environment file, OpenStack RC file has parameters to perform authentication and installation on OpenStack. The --os_auth_url must be specified while passing the parameters. --os_auth_url specifies the secure (https) or unsecured (http) keystone URL used by OpenStack for authentication.
• Add certificate for standalone (only) during the bootup time, i.e, during the ESC VM installation:
./bootvm.py test-vm --image <image_name> --net <network> [--cert_file CERT_FILE]
[--confd_aes_key CONFD_AES_KEY]
/home/cisco/openstack.crt
--user_pass <username>:<password> --user_confd_pass <username>:<password>

Removing a Root Certificate
Note Currently, ESC does not support adding a certificate for HA Active/Standby during the installation as the keepalived service is not running when a certificate is added.
• Add certificate for standalone/HA Active/Standby after booting up the ESC instance. The escadm tool has an truststore add option which has the following arguments: The --file argument refers to the CA certificate file. Using this argument you can import any file format supported by the java keytool: X.509
v1, v2, and v3 certificates, and PKCS#7. The --alias argument is unique and refers to the name this specific CA certificate is given.
1.
Copy/Transfer CA Certificate file to ESC master VM .
2.
Add certificate to ESC truststore. To do this, execute the following command: sudo escadm escadm truststore add --alias [ca cert alias] --file [file path] or sudo escadm truststore escadm truststore --alias [ca cert alias] --file [file path]
3.
Verify the certificate is added.
sudo escadm truststore show or sudo escadm truststore show
Removing a Root Certificate
The escadm tool has a 'truststore delete' option which only takes --alias argument. The --alias argument refers to the name of the CA certificate to be deleted. Use this argument on the standalone/HA Active/Standby ESC
VM:
Procedure
Step 1
Step 2
On (master) ESC use escadm to delete certificate from ESC truststore.
sudo escadm truststore delete --alias [ca cert alias] or sudo escadm truststore truststore delete --alias [ca cert alias]
Verify the certificate is removed.
sudo escadm truststore show or sudo escadm truststore show

Managing Root Certificates During the Upgrade
Managing Root Certificates During the Upgrade
• Image Upgrade : If you are backing up the ESC DB for upgrade, then no other action is required, the
ESC truststore will be restored once the ESC DB is restored. If you are not backing up the ESC DB for upgrade, then each CA certificate needs to be added again to the ESC truststore.
• RPM Upgrade : This upgrade method keeps the ESC truststore as is, i.e. all ca certificates in the ESC truststore should remain there after upgrade.
Managing Keystore in Cisco Elastic Services Controller
The keystore is a storage for certificates and keys that an application uses to authenticate itself with different clients.
ESC Keystore holds only one certificate, that is used by all the applications for example, ESCManager,
VIMManager, MONA, and so on.
ESCADM provides multiple commands to manage the keystore.
When deploying ESC for the first time, a self signed certificate is created and stored in the keystore by default.
important Notes:
• In an Active/Active mode, the default certificate Common Name (CN) is db.service.consul
. If you want to set a new certificate, you must set it with the same CN, otherwise, you must add the following configuration to the heat template of all the nodes to disable the certificate validation in MONA when deploying the ESC: mona: certificate_validation: false
• All the escadm keystore commands require root privileges to be executed on the ESC.
ESCADM Keystore Commands
• escadm keystore show
The escadm keystore show command displays information about the certificate currently stored in the keystore. It shows informations like, the creation date, Alias, and certificate fingerprint.
For example:
$ sudo escadm keystore show
Keystore type: PKCS12
Keystore provider: SUN
Your keystore contains 1 entry esc, Apr 13, 2020, PrivateKeyEntry,
Certificate fingerprint (SHA1):
FF:11:66:3E:93:DD:3A:0B:9A:72:40:16:35:34:D2:22:E1:25:07:80
• escadm keystore export [--out <file path>]
The export command displays the full content of the certificate. If the out option is specified, the content is saved in a file whose path is specified in the previous option.
• escadm keystore set-- file <file path>
Cisco Elastic Services Controller 5.3 Install and Upgrade Guide
17
Installing Cisco Elastic Services Controller on OpenStack
ESCADM Keystore Commands
The set command replaces the current certificate with a new one residing inside the file whose path is specified in the option file
.
Ensure that the file is in PEM format, containing both the certificate and a private key.
The following example shows how to generate a new self-signed certificate and set it to the keystore:
1.
Use the following command to generate the certificate: openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out cert.pem
The previous commands gives the following two files: key.pem
and cert.pem
2.
Use the following commands to combine the two files: cat key.pem > server.pem
cat cert.pem >> server.pem
3.
To set the new certificate to the keystore, use the following command:
$ sudo escadm keystore set --file server.pem
Service "keystore" successfully updated ESC keystore and will take effect once ESC services are restarted by running "sudo escadm restart"
Note Ensure that you delete any left over files containing private keys and certificate after the setting is done.
It is mandatory to restart your system for the change to take effect. Use the following command to restart in standalone mode or H/A mode: sudo escadm restart
If the ESC is running in the Active/Active mode, you must restart all the nodes in the same cluster.
However, if the ESC is running in an Active/Active GEO mode, you must stop the GEO service on all the clusters, to make sure a GEO switchover does not take place.
Only in GEO Active/Active mode, to stop GEO service, log in to any node in each cluster and use the following command:
$ sudo escadm geo stop --cluster
You can login to any node in the cluster where the certificate is originally set. Use the following command:
$ sudo escadm stop --cluster
$ sudo escadm start --cluster
If you are on a GEO Active/Active mode, once all the node are up and running in passing state, login again to any node to start the GEO service. Use the folowing command to start the service:
$ sudo escadm geo start --cluster

Using a Bootable Volume in ESC Installation
A volume in OpenStack is a detachable block storage device that can be attached to an ESC instance. You can store and also run ESC instances from a volume.
Note • Only one ESC instance can be launched from one volume at a time.
• ESC installation with a combination of bootable volume and high availability (Active/Standby and
Active/Active) on cinder is not supported.
To launch an ESC instance from a bootable volume, do the following:
Procedure
Step 1
Step 2
Create a bootable volume in OpenStack based on an ESC image or from a bootable volume. The bootable volume must be at least of 30 GB disk size. For more information, see OpenStack documentation.
Deploy ESC VM using the bootvm.py
command and choose the
--boot_volume argument instead of the
--image argument, as shown below:
./bootvm.py <esc_vm_name> --boot_volume <volume_name_or_id> --net <network> --user_pass
<username>:<password>
--user_confd_pass <username>:<password> --flavor <flavor_name>
Note • Only one of these arguments,
--image or
--boot_volume must be passed to the bootvm.py
command. The installation will fail, if both or none of the arguments are used.
• When launching an ESC instance from a bootable volume, volume disk size is considered over the flavor disk size.
• If an ESC instance is deleted, the volume attached to it will not be deleted, as the volume was created out-of-band.

High Availability Active/Standby Overview
ESC supports High Availability (HA) in the form of Active/Standby and Active/Active models. For
Active/Standby model, two ESC instances are deployed in the network to prevent ESC failure and provide
ESC service with minimum service interruption. If the primary ESC instance fails, the standby instance automatically takes over the ESC services. ESC HA Active/Standby resolves the following single point failures:
• Network failures
• Power failures
• Dead VM instance
• Scheduled downtime
• Hardware issues
• Internal application failures
Note From ESC 5.0, the name, Active/Passive model is changed to Active/Standby model.
Cisco Elastic Services Controller 5.3 Install and Upgrade Guide

ESC Active/Standby Architecture
ESC Active/Standby Architecture
Figure 1: Cisco Elastic Services Controller Active/Standby Architecture
Installing Cisco Elastic Services Controller on OpenStack
How High Availability Works
ESC HA Active/Standby network can be either set up as a single installation of a ESC HA Active/Standby pair or deployed as two standalone ESC nodes that are converted into HA pair after re-configuring these nodes post deployment. The HA deployment consists of two ESC instances: a primary and a standby. Under normal circumstances, the primary ESC instance provides the service. The corresponding standby instance is passive.
The standby instance is in constant communication with the primary instance and monitors the primary instances' status. If the primary ESC instance fails, the standby instance automatically takes over the ESC services to provide ESC service with minimum interruption.
The standby also has a complete copy of the database of the primary, but it does not actively manage the network until the primary instance fails. The KeepAliveD service monitors both primary and standby instances activity status. When the primary instance fails, the standby takes over automatically. The standby instance takes over primary instance to manage the services while primary instance restoration is taking place.
When the failed instance is restored, if required you can manually initiate a switch-over and resume network management via the primary instance.
Both primary and standby ESC instances are connected to the northbound orchestration system through an
IPv4 or IPv6 network. For the northbound system, a unique virtual IP address is assigned to access the current primary ESC High Availability Active/Standby instance. The deployed VNFs are connected to both ESC primary and standby instances through another IPv6 network.
ESC HA Active/Standby nodes are managed by KeepAliveD and DRBD (Replication tool to keep the ESC database synchronized) sync network services. While the KeepAliveD service monitors both primary and standby instances status, the DRBD service monitors primary instance DB and sync the changes to the standby instance DB. These two services can be co-located on same VIP network or in two separate networks. VM handshake between ESC instances occurs through the KeepAliveD over the IPv4 or IPv6 network.

Deploying ESC High Availability Active/Standby
Deploying ESC High Availability Active/Standby
To deploy Cisco Elastic Services Controller (ESC) High Availability (HA) Active/Standby, ESC standalone instances can be installed on two separate nodes - Primary and Standby. For more information see,
Availability Works, on page 22
. You can connect the Primary and Standby instances to either a Cinder volume or Replication based volume (DRBD).
The following deployment mechanisms can be used to deploy ESC HA Active/Standby:
• Internal Storage—When ESC HA Active/Standby is configured with Internal storage, the Primary and the Standby instances have individual databases which are always synchronized. In this solution, ESC
HA Active/Standby is designed with database replication and DRBD is used as the tool for disk-level replication. The database in the Primary instance simultaneously propagates the data to the database in the Standby instance thus requiring no external storage. In the event of a Primary instance failing, the
Standby instance get assigned the role of the Primary instance along with its own synchronized database.
ESC HA Active/Standby is deployed using Internal storage, the ESC instances reply on the virtual IP address (that is kad_vip argument), and the interface of vrrp instance (that is kad_vif argument) to select the Primary ESC instance. To establish a reliable heartbeat network, it is recommended that the Primary and Standby ESC instances are on different physical hosts. The reliability of the physical links between the ESC instances (such as, network interface bonding) can also be taken into consideration.
• Replicate External-Storages — In this type of architecture, ESC HA Active/Standby is configured with
DRBD and both Primary and Standby instance store their data in two external storages (OpenStack
Cinder volumes). Each ESC node is attached by a Cinder volume and ESC data files are stored in the cinder volume. The data in two ESC node are synchronized through the database replication mechanism provided by DRBD.
The table lists the differences between the HA Active/Standby options :

(occurs when both ESC nodes have problems).
The data consistency may be affected in a double fault condition (occurs when both
ESC nodes have problems).
Deploying ESC in High Availability Active/Standby Mode on Internal Storage
When you boot ESC instances on Primary and Standby instances, you need to specify the following bootvm.py
command arguments to deploy ESC HA Active/Standby on an internal storage:
• kad_vip
Note When ESC HA Active/Standby is deployed, the kad_vip argument allows end users to access the Primary ESC instance.
• kad_vif
• ha_node_list
These arguments enable the bootvm.py
command to automatically set up the internal storage on the OpenStack.
For more information on using the bootvm.py
command arguments, see Appendix A: Cisco Elastic Services
Controller Installer Arguments.
To deploy ESC HA Active/Standby instances, use the bootvm script on both the nodes with the following arguments:

You can also use escadm tool to re-configure ESC HA Active/Standby parameters on each of the standalone
ESC VMs. Three parameters "--ha_node_list , --kad_vip, --kad_vif" are all required to configure ESC HA
Active/Standby.
Note You should make sure that both the standalone ESC VMs health check is passed before running the below commands to perform HA Active/Standby configuration.
For example:
$ sudo bash
$ escadm ha set --ha_node_list='<ESC_HA_NODE1_IP> <ESC_HA_NODE2_IP>' --kad_vip <virtual IP address> --kad_vif <VRRP_Interface_Instance>
$ sudo escadm reload
$ sudo escadm restart
Deploying ESC in High Availability Active/Standby Mode on Replicate External Storage
Replicate external storage ESC HA Active/Standby requires two cinder volumes for database storage.
Before you begin
• Networks and IP addresses that both ESC instances will connect to
• Keepalived interface and virtual IP for HA Active/Standby switchover
Procedure
Step 1
Step 2
Step 3
Create two cinder volumes in OpenStack. The configured cinder volume size should be 3GB.
$ cinder create --display-name cindervolume_name_a[SIZE]
$ cinder create --display-name cindervolume_name_b[SIZE]
Check the status of the created cinder volume and find the uuids for deployment.
$ cinder list
Deploy ESC HA Active/Standby instances. Use the bootvm script on both the nodes with the following arguments:
ON HA NODE 1:
$ ./bootvm.py <ESC_HA_Node1>\
--user_pass <username>:<password>\
--user_confd_pass <username>:<password>\
--gateway_ip <default gateway IP address>\
--net <network name1>\
--ipaddr <static ip address>\

After both VMs are rebooted; the keepalived state on one of ESC VM should be one of ESC VM should be in MASTER state and the other one should be in BACKUP state. You can check ESC HA Active/Standby state by using following command: $ sudo escadm status --v .
Configuring the Northbound Interface Access
When you configure ESC HA Active/Standby, you can also specify a virtual Anycast IP address to the HA
Active/Standby pair. The northbound interface as well as the service portal uses virtual Anycast IP address to access the ESC Primary HA Active/Standby instance. When deploying ESC HA Active/Standby, use the following arguments with the ./bootvm.py
script.
• --ha_node_list
• --kad_vip
• --kad_vif
For more details on these arguments, see section Appendix A: Cisco Elastic Services Controller Installer
Arguments .
The following section explains how to configure ESC HA Active/Standby with multiple interfaces and to configure the virtual Anycast IP address.
Configuring ESC HA Active/Standby with Multiple Interfaces
You can configure ESC HA Active/Standby with DRDB synchronization and VRRP heartbeat broadcasting on a network interface for data synchronization and VNF monitoring. You can use an additional network interface to allocate Virtual IP for the northbound access. To configure the multiple interfaces on ESC HA
Active/Standby nodes, use --ha_node_list, --kad_vip, --kad_vif arguments to specify these multiple network interfaces configuration. For details on these arguments, see section Appendix A: Cisco Elastic Services
Controller Installer Arguments .
26
Cisco Elastic Services Controller 5.3 Install and Upgrade Guide
Installing Cisco Elastic Services Controller on OpenStack
Configuring the ESC HA Active/Standby Virtual IP Address
Note KeepAlived doesn’t support single IPv4 VIP address with a IPv6 VRRP instance.
Example configuration steps are shown below:
./bootvm.py <esc_ha1> \
--user_pass <username>:<password>
--user_confd_pass <username>:<password>
--image <image_id> \
--net <net-name> \
--gateway_ip <default_gateway_ip_address> \
--ipaddr <ip_address1> <ip_address2> \
--ha_node_list < IP addresses HA nodes1> < IP addresses for HA nodes2> \
--kad_vip <keepaliveD VIP of the HA nodes and the interface for keepaliveD VIP> \ (for example: --kad_vip 192.0.2.254:eth2)
--kad_vri <virtual router id of vrrp instance>
--kad_vif <virtual IP of the HA nodes or the interface of the keepalived VRRP> \ (for example: --kad_vif eth1 )
--ha_mode <HA installation mode> \
--route <routing configuration> \ (for example:192.0.2.254/24:192.168.0.1:eth1 )
--avail_zone nova:<openstack zone> \
Similarly, a three network interface can be configured for ESC HA Active/Standby nodes. An example three interfaces configuration is shown below with the following assumptions :
• Network 1 is an IPv6 network used for northbound connection. ESC VIP is allocated in this network and the Orchestrator send requests to ESC through ESC VIP.
• Network 2 is an IPv4 network used for ESC sync traffic (DRDB synchronization) and VRRP heartbeat.
This network is also used for OpenStack connection and VNF monitoring.
• Network 3 is another IPv4 network used for management. The SA, rsyslog, etc. can use this network to manage ESC.
./bootvm.py esc-ha-0 --image ESC-2_2_x_yyy --net network-v6 network --gateway_ip 192.168.0.1 --ipaddr
2001:cc0:2020::fa 192.168.0.239 192.168.5.239 --ha_node_list 192.168.0.239 192.168.0.243 --kad_vip
[2001:cc0:2020::fc/48]:eth0 --kad_vif eth1 --ha_mode drbd --route 172.16.0.0:eth1 --avail_zone nova: zone name
./bootvm.py esc-ha-1 --image ESC-2_2_x_yyy --net network-v6 network lab-net-0 --gateway_ip 192.168.0.1
--ipaddr 2001:cc0:2020::fa 192.168.0.239 192.168.5.239 --ha_node_list 192.168.0.239 192.168.0.243 --kad_vip
[2001:cc0:2020::fc/48]:eth0 --kad_vif eth1 --ha_mode drbd --route 172.16.0.0:eth1 --avail_zone nova: zone name
Configuring the ESC HA Active/Standby Virtual IP Address
In this option, the value of kad_vip argument should be a virtual IP, which allows the service portal and the northbound to access the Primary ESC and send requests to ESC HA Active/Standby service through virtual
IP (VIP).
If northbound and both ESC HA Active/Standby nodes are located in the same network, you can connect directly through the virtual IP (VIP). If northbound doesn't sit on the same network as ESC HA Active/Standby, assign a floating IP to ESC HA Active/Standby VIP using the procedure below:
1.
Create a port with the VIP address (kad_vip) in the same network as ESC's kad_vip connects.
neutron port-create network --name network_vip --fixed-ip subnet_id=network-subnet,ip_address=192.168.0.87

Configuring the ESC L3 HA Active/Standby With BGP
2.
Deploy ESC HA Active/Standby . See Configuring High-Availability Active/Standby section in Installing
ESC on OpenStack.
Note Make sure the kad_vip using the same IP address as the port created above.
3.
Associate a floating IP with the port created above. The first uuid is the floating ip id and the second one is the port id.
neutron floatingip-associate <floating IP> <port ID>
Access ESC HA Active/Standby through the floating IP and it will connect to the ESC Primary node.
4.
For the portal access, make sure the keepalive network is accessible by your browser and the virtual IP is the IP address to access the portal of the Primary node.
For example, if the VIP is 192.0.2.254, access ESC HA Active/Standby portal with https://192.0.2.254:9001/.
Configuring the ESC L3 HA Active/Standby With BGP
To configure BGP for ESC HA Active/Standby, there are two options:
1.
Directly booting ESC HA Active/Standby L3 with BGP
2.
Using post configuration from existing ESC HA Active/Standby pair
To configure BGP for ESC HA Active/Standby, the following network parameters are required:
• BGP remote IP
• IP of the interface for BGP anycast routing
• BGP local AS number for routing configuration
• BGP remote AS number for routing configuration
• BGP routing configuration
• --bgp_local_ip
• --bgp_local_router_id
Note You must configure BGP router with neighbors, and restart it. Verify that the router is able to ping the AnyCast
IP.
On the BGP router, set two neighbors. The below BGP configuration is designed for Bird router. The configuration is router specific. For each types of router, the procedure is different:
The below configurations are given according to the bootvm command : protocol bgp E3 from EXABGP { neighbor 198.18.42.222 as 65012;
}

Important Notes
• ESC HA Active/Standby
• An HA Active/Standby failover takes about 2 to 5 minutes. The ESC service will not be available during the switchover time.
• When the switchover is triggered during transactions, all incomplete transactions will be dropped.
The requests should be re-sent by northbound if it does not receive any response from ESC.
• External Storage
• If the Primary ESC instance is suspended by OpenStack command, the switch over will be triggered but the cinder volume won't be attached to the new Primary ESC instance. This is not a valid use case for ESC HA Active/Standby.
• Internal Storage
• Two ESC instances have to be deployed to establish the HA Active/Standby solution. The ESC HA
Active/Standby will start to work when both ESC instances are successfully deployed and are able to connect to each other. If you just deploy one ESC instance with HA Active/Standby parameters, the ESC instance keeps Switching-to-Master state and will not be able to provide any service until it reaches its peer.
• Split-brain scenario can still happen in this ESC HA Active/Standby solution, although the chance is very low.
• ETSI-specific Notes
ESC supports ETSI MANO northbound API defined by the European Telecommunications Standards
Institute (ETSI) for NFV Management and Orchestration. The ETSI MANO API is another programmatic interface based on the REST architecture. For more information, see ETSI MANO Compliant Lifecycle
Operations in the Cisco Elastic Services Controller User Guide . Consider the following notes while enabling ETSI service on ESC which is in HA Active/Standby mode:
• The server.address value in the etsi-vnfm.properties
file must be set to a Virtual IP (VIP) address.
This IP address can be used to communicate back to the ETSI services using API callbacks. If the virtual IP address is not specified, the ETSI service startup may fail.
Cisco Elastic Services Controller 5.3 Install and Upgrade Guide

Installing Cisco Elastic Services Controller on OpenStack
Troubleshooting High Availability Active/Standby
• The ETSI VNFM service and the escadm script generate and maintain the security.user.name and security.user.password property values. You should not change it manually.The
security.user.password is encoded.
Troubleshooting High Availability Active/Standby
• Check for network failures. If a network problem occurs, you must check the following details:
• The IP address assigned is correct, and is based on the OpenStack configuration.
• The gateway for each network interface must be pingable.
• Check the logs for troubleshooting:
• The ESC Admin logs at /var/log/esc/escadm.log
• The ESC manager log at /var/log/esc/escmanager.log
• The AA elector log at /var/log/esc/elector-{pid}.log
• Check for DRBD (Replication based ESC HA Active/Standby) for Internal Storage solution:
• Check the DRBD configuration file at
/etc/drbd.d/esc.res
• Access the DRBD log
•
/var/log/messages|grep drbd
• To collect log files through CLI, use the following command on all ESC nodes: sudo escadm log collect

Cisco Elastic Services Controller Active/Active HA Overview
ESC supports High Availability (HA) in the form of an Active/Active model. ESC Active/Active HA has three VMs as a cluster in one datacenter.. There are two datacenters. Between the two datacenters, one datacenter acts as active, another acts as standby. ESC Active/Active HA uses Openstack heat template to deploy the three VM cluster in a datacenter.
In a datacenter, ESC service runs on each VM; however, there is only one ESC on a datacenter that runs as cluster leader. DB service runs only on the leader. The ESC services on the other two ESC VMs run as cluster follower. The DB service is only active on ESC services leader VM.
DRBD synchronises the data among ESC VMs. The ESC service on the three ESC VMs connect to the active
DB service. When a leader switchover happens, all the ESC service connects to the newly active DB service.

Installing Active/Active High Availability Cluster
To configure the Active/Active HA cluster, you can run the following commands on OpenStack, where openrc my-server is openrc for the OpenStack, and test is the stack name.
source ~/elastic-services-controller/esc-bootvm-scripts/openrc my-server-42 openstack stack create test -t aa.yaml
To check the status of the stack, use the following commands:
• openstack stack list
• openstack stack show test
• openstack stack event list test
Once the stack is in
CREATE_COMPLETE status, you can ssh into the VMs. The openstack stack show test command lists the IP addresses for the 3 VMs, you can use them to access to the VMs.
Note The Active/Active HA Cluster is deployed on OpenStack only.
Setting up the User Configuration
You can configure some of the parameters based on your settings, such as network, subnet, using either static
IP or DHCP to allocate IP address, flavor, image, password, etc. The configurable parameters are available in aa-param.yaml
, Openstack heat environment file, when the ESC cluster is instantiated via heat template
( aa.yaml
).
To instantiate ESC cluster, use the following example:

Adding Default VIM Connector to the Active/Active High
Available Cluster
You can add a default vim connector to the 3 ESC VM cluster in the following two different ways:
1.
Once the 3 ESC VM cluster boots up, use netconf interface to add a default vim connector by using the following command. The vim.xml
is the default vim connector deployment file.
[admin@name-esc-1 ~]$ esc_nc_cli --host db.service.consul --user admin --password
<admin_password> edit-config vim.xml
2.
To configure a default vim connector, you must add the default vim connector configuration inside the heat template day0 file. Add the following block in the write_files section under the cloud-config in aa-day0.yaml file. Once the 3 ESC VM cluster boots up, it creates a default vim connector by its own.
The following example shows how to configure default vim connector in heat template day0 file:
- path: /opt/cisco/esc/esc-config/esc_params.conf
content: | openstack.os_auth_url=http://172.16.103.38:35357/v3 openstack.os_project_name=admin openstack.os_tenant_name=admin openstack.os_user_domain_name=default openstack.os_project_domain_name=default openstack.os_identity_api_version=3 openstack.os_image_api_version=2 openstack.os_username=admin openstack.os_password=password1
Adding BGP in an Active/Active Cluster
To initiate the BGP process, add the anycast IP to the lo device. You can configure it in sys-cfg.yaml
.
For example:
#cloud-config write_files:
- path: /etc/cloud/cloud.cfg.d/sys-cfg.yaml
content: | network: version: 1 config:
- type: physical name: lo subnets:

Managing Cluster in ESC Active/Active High
Availability
This chapter contains the following section:
•
Managing Cluster in ESC Active/Active High Availability, on page 41
Managing Cluster in ESC Active/Active High Availability
To do cluster management in ESC Active/Active HA, you can call some escadm commands on any ESC node and execute it on all nodes in Active/Active cluster.
The following are the supported commands for cluster level calling:
• escadm start
• escadm stop
• escadm geo start/stop
• escadm vim show
Add the option
--cluster to execute any of the previous commands to be executed on all nodes in
Active/Active local cluster:
For example: sudo escadm geo start --v –cluster
The output of the command and exit code of each node are displayed with the IP address of that node to distinguish the execution output, and the output on the local node.
Example for escadm geo start --cluster
:
[root@name-geo-2-1 admin]# escadm geo start --cluster
192.168.1.13 # remote host exit status : 0
Starting geo service: [OK]
192.168.1.12 # remote host exit status : 0
Starting geo service: [OK]
Starting geo service: [OK] # output of the local node

Configuring GEO in Active/Active High Availability
ESC Active/Active HA has three VMs as a cluster in one datacenter. The second datacenter consists of
GEO-HA.
Following are the 6 pre-defined roles in GEO:
1.
init
: initial role of geo service
2.
pre_primary
3.
primary
4.
pre_secondary
5.
secondary
6.
unknown
: used when consul is not reachable
GEO can change one role to another. Transitions are defined in esc-config.yaml
. Each transition is divided into the following 3 parts:
• from
: current role
• goto
: destination role
• condition
: when GEO changes the role
Transition Conditions
When A/A HA Geo comes up, the primary datacenter has to go through init
, pre_primary
, and primary states; meanwhile, the secondary datacenter has to go through init, pre-secondary, and secondary states. When
Cisco Elastic Services Controller 5.3 Install and Upgrade Guide
43
Installing Cisco Elastic Services Controller on OpenStack
Transition Conditions all ESC VMs' health check pass on both primary and secondary datacenters, the ESC A/A HA GEO is up and running. It is ready for use.
Condition Functions
The following are all supported condition functions:
1.
return
: do nothing but return the argument
2.
and
: return true if all arguments are true
3.
or
: return true if any of the argument is true
4.
len
: return the length of the argument
5.
equals
: return true if all arguments are equal
6.
true
: return true if args can be tested for truth value in python
7.
false
: opposite to 'true'
The following are samples for GEO configurations on primary datacenter: on_init: consul start on_primary: start on_secondary: stop on_stop: consul stop startup: manual transitions:

Active/Active GEO HA Failure Injection Limitations
The ESC Active/Active GEO HA is enhanced to support a one-way GEO HA failover with a maintenance window to move it back to healthy state.
If a GEO failover happens and the ESC VMs move to the unhealthy state, use the following steps to bring
ESC A/A GEO HA back to the healthy state through manual intervention:
Procedure
Step 1 Resolve any issues in Datacenter1 (DC1), that may have caused the failures and enabled the GEO switch to
Datacenter2 (DC2).

DRBD Encryption for ESC Active/Standby and
Active/Active HA Data Replication
This chapter contains the following sections:
•
DRBD Encryption for ESC HA Data Replication , on page 49
•
ESC HA with DRBD Encryption, on page 49
DRBD Encryption for ESC HA Data Replication
ESC uses DRBD for data replication across different nodes in an HA cluster environment. DRBD layers logical block device over existing local block devices on cluster nodes.
The written data to the primary node is transferred to the lower-level block device and simultaneously propagated to the secondary node(s). Currently ESC mounts DRBD device directly on
/opt/cisco/esc/esc_database
.
For Example:
# df
Filesystem devtmpfs tmpfs tmpfs
…
1K-blocks

/dev/mapper/esc_crypt 3028620 57212 2797848 3% /opt/cisco/esc/esc_database
Block device encryption encrypts or decrypts the data transparently as it is written/read from block devices, the underlying block device sees only encrypted data.
Security is enhanced with the dm-crypt/LUKS layer to encrypt the data in DRBD partition, between filesystem and DRBD device. LUKS (Linux Unified Key Setup) is a specification for block device encryption.
ESC HA with DRBD Encryption
The following bootvm commands boot ESC HA with DRBD encrypted:
Select DRBD LUKS encryption through bootvm.py. There are 4 variations that result in the equivalent ESC day-0 user-data/esc-config.yaml when passed to the ESC VM instance.
Cisco Elastic Services Controller 5.3 Install and Upgrade Guide

ESC HA with DRBD Encryption bootvm.py --fs_encryption_type luks --fs_luks_key_prompt bootvm.py --fs_encryption_type luks --fs_luks_key 'LuksKeyValue'

=> injects a local file containing the luks key
The following command shows an advanced usage to manage the luks key file at a different path on the ESC
VM filesystem: bootvm.py --fs_encryption_type luks --fs_luks_key_file path-on-esc-vm-luks-key-file
--fs_luks_key_prompt bootvm.py --fs_encryption_type luks --fs_luks_key_file path-on-esc-vm-luks-key-file

=> injects the luks key as read from a local file into a different file location
Use the following commands if you are installing ESC with a custom user-data, such as ESC Active/Active deployment with heat templates:
The luks key is specified as a day-0 file and an attribute under esc-config.yaml / filesystem.
Encode the luks key as base64: base64 <<<'LuksKeyValue'

vCenter Resources
Resources to be created/installed on vCenter:
• Datacenters : At least one datacenter. For more details, see the Important Notes below.
• Hosts : Host configuration based on your targeted performance objectives. Each Host under the single vDS must have at least two physical Network Interface Card (NIC) connected, (one for vCenter
Cisco Elastic Services Controller 5.3 Install and Upgrade Guide
57
Installing Cisco Elastic Services Controller on VMware vCenter
Important Notes
Management Interface by default, and the other used to assign to VDS's uplink portgroup). This setup is required for data access across hosts.
• Compute Clusters : Clusters can be created to group several hosts together.
• Datastores : Shared datastore is required if user wants to leverage DRS.
• Distributed Switches : At least one distributed switch that will contains all the VNF supporting networks.
Important Notes
Keep in mind the following important notes while installing ESC on a VMware:
• A single ESC instance will only support:
• Multiple Datacenter supported deployment, network, image, subnet creation
• One vSphere Distributed Switch (VDS)
• DPM, HA Active/Standby, and vMotion must be off.
• If DRS is enabled, it has to be in the "Manual Mode".
• Fault Tolerance is not supported.
• Datastore Cluster is not supported, only flat datastore(s) structure under the cluster or under the datacenter are supported.
• ESC only supports a default resource pool. Adding and creating resource pools are not supported.
• Image (Template) created through ESC are stored under /esc-ovas folder .
• Day-0, smart license, and other supported files are packed into a ISO file, and uploaded to the same folder where the VM rest, then mount it as a CD-ROM to the VM.
• ESC/VIM does not respond for the name and file content passed in for generating ISO file. They have to be provided according to each template's requirements. e.g. for ASAv, the day-0 config has to be named as "day0-config", and smart license token has to be named as "idtoken".
• When you see the error message "Networking Configuration Operation Is Rolled Back and a Host Is
Disconnected from vCenter Server", it is due to a vCenter's limitation. See the Troubleshooting guide , page 91 to increase the timeout for rollback.
• The following VM features and operations are not supported in all versions of the Cisco CSR 1000V. If still these operations are used or performed, there may be risk of encountering dropped packets, dropped connections, and other error statistics.
1.
DRS
2.
Suspend

Cisco Elastic Services Controller 5.3 Install and Upgrade Guide
Installing Cisco Elastic Services Controller on VMware vCenter
Important Notes
• Although deployments can be processed without shared storage, ESC does not guarantee optimized computing resource. Shared storage(s) should associate with as many as possible hosts, which will give more opportunity to DRS to balance resources.
• Every time a redeploy happens as part of recovery on VMware, VM's interface(s) will have different
MAC addresses.
• All the VM group defined in a datamodel must accompany with a "zone-host" placement policy, meaning the deployment has to be either host-targeted or cluster-targeted.
• Recovery may fail, if a VM has PCI/PCIe passthrough device(s) attached, when it's recovered to a computing-host (picked based on ESC placement algorithm) which does not have any PCI/PCIe passthrough enabled device available .
• For PCI/PCIe passthrough working, DRS has to be off .
• If you experience a PowerOn error on a VM that has PCI/PCIe passthrough device(s) attached to it, update the VM or the image (template) the VM is cloned from, using the solution described here .

•
Installing Cisco Elastic Services Controller on VMware vCenter, on page 61
•
Next Steps: Cisco Elastic Services Controller Virtual Machine, on page 67
Installing Cisco Elastic Services Controller on VMware vCenter
Cisco Elastic Services Controller can be installed in a VMware ESXi hypervisor and can be accessed or managed using vSphere client of VMware. You can install Cisco Elastic Services Controller in a VMware environment using an Open Virtual Appliance (OVA) package.
The VMware vSphere client can be connected directly to your ESXi installation, or it can be connected to a vCenter server which in turn is connected to your vSphere installation. Connecting through vCenter provides a number of capabilities that connecting directly to ESXi does not. If a vCenter server is available and associated with the ESXi installation, it should be used.
Preparing to Install Cisco Elastic Services Controller
In order to install Cisco Elastic Services Controller and configure its network connection, you have to answer several questions. Some of these questions concern the networking environment in which the virtual machine is being installed, and some of them concern values which are unique to the particular virtual machine being installed.
Before you perform the installation, ensure that you are prepared by reviewing this checklist:

High Availability Active/Standby Overview
ESC supports High Availability (HA) in the form of Active/Standby and Active/Active models. For
Active/Standby model, two ESC instances are deployed in the network to prevent ESC failure and provide
ESC service with minimum service interruption. If the primary ESC instance fails, the standby instance automatically takes over the ESC services. ESC HA Active/Standby resolves the following single point failures:
• Network failures
• Power failures
• Dead VM instance
• Scheduled downtime
• Hardware issues
• Internal application failures
Note From ESC 5.0, the name, Active/Passive model is changed to Active/Standby model.

Installing Cisco Elastic Services Controller on VMware vCenter
How High Availability Active/Standby Works
How High Availability Active/Standby Works
A High Availability Active/Standby deployment consists of two ESC instances: a primary and a standby.
Under normal circumstances, the primary ESC instance provides the services. The corresponding standby instance is passive. The standby instance is in constant communication with the primary instance and monitors the primary instances' status. If the primary ESC instance fails, the standby instance automatically takes over the ESC services to provide ESC service with minimum interruption.
The standby also has a complete copy of the database of the primary, but it does not actively manage the network until the primary instance fails. When the primary instance fails, the standby takes over automatically.
Standby instance takes over primary instance to manage the services while primary instance restoration taken place.
When the failed instance is restored, failback operations can be initiated to resume network management via the original primary instance.
ESC instances are managed by using KeepAliveD service. The VM handshake between ESC instances occurs through the KeepAliveD over the IPv4 network.
Deploying ESC High Availability Active/Standby with User Data
(HA Active/Standby Pair)
Before you begin:
• Cisco Elastic Services Controller (ESC) High Availability (HA) Active/Standby requires a network to keep alive and replicate database between primary and standby nodes. Both ESC VMs must have at least one network interface connecting to the same network and must be able to communicate to each other through the network.
• Ensure the two ESC VMs are located in different hosts and datastores so that single point failures can be prevented.
You can deploy ESC HA Active/Standby on VMware vCenter or vSphere in either of two ways:
• Deploying ESC HA Active/Standby with user data as a High Availability Active/Standby pair (Supported from ESC 4.2)
• Deploying ESC HA Active/Standby as two standalone instances and then using post configuration to set them as a High Availability pair. For more information,see the section on "Deploying ESC High
Availability Active/Standby (Standalone Instances)".
To deploy ESC HA Active/Standby on VMware vCenter or vSphere with user data as a High Availability
Active/Standby pair, define the user data file for each HA Active/Standby instance and then point the user data for each instance via ovftool. The encoding of user data is done via a set of commands in the ovftool script, and the result of this is set as a variable to the –prop:user-data= property in the ovftool.
Note The admin user/password and confd user/password properties are mandatory OVF properties. These properties cannot be defined in the user-data files.

• Once the VMs are deployed successfully, you can check the status of ESC HA Active/Standby. You will find that one VM instance is booted as MASTER while the other VM instance is a BACKUP.
Deploying ESC High Availability Active/Standby (Standalone
Instances)
To deploy ESC HA Active/Standby on VMware vCenter or vSphere, two separate standalone nodes need to be installed first. After the standalone ESC instances are installed, reconfigure these nodes to turn them into
Primary and Standby using the following:
• kad_vip
• kad_vif
• ha_node_list
Note • On each ESC VM, we need to run escadm tool to configure ESC HA Active/Standby parameters and then reload and restart the escadm service.
• When you are deploying ESC HA Active/Standby, the kad_vip argument allows end users to access the
Primary ESC instance.
Procedure
Step 1
Step 2
Log in to the ESC Standalone instances.
As an admin user, run the escadm tool on both the Primary and Standby instances and provide the corresponding arguments.
• kad_vip — Specifies the IP address for Keepalived VIP (virtual IP) plus the interface of Keepalived VIP
[ESC-HA Active/Standby]
• kad_vif — Specifies the interface for Keepalived virtual IP and keepalived VRRP [ESC-HA
Active/Standby]. You can also use this argument to only specify the interface for keepalived VRRP, if the VIP interface is already specified using the kad_vip argument.
74
Cisco Elastic Services Controller 5.3 Install and Upgrade Guide
Installing Cisco Elastic Services Controller on VMware vCenter
Important Notes for ESC HA Active/Standby
• ha_node_list — Specifies list of IP addresses for HA Active/Standby nodes in the Primary/Standby cluster for DRDB synchronization. This argument is utilized for replication-based HA Active/Standby solution only. For ESC instances with multiple network interfaces, the IP addresses should be within the network that --kad_vif argument specifies .
Step 3
Step 4
Step 5
$ sudo escadm ha set --kad_vip= <ESC_HA_VIP> --kad_vif= <ESC_KEEPALIVE_IF> --ha_node_list=
<ESC_NODE_1_IP> <ESC_NODE_2_IP>
$ sudo escadm reload
$ sudo escadm restart
After the restart, one ESC VM should be in Primary state and the other one should be in Standby state.
Add the VIP to the allowed address pairs for both VMs so that the VIP is reachable from outside.
Verify the status of each ESC instance.
# sudo escadm status
The following table lists few other command to check the status:
Status
ESC HA Active/Standby Role
CLI Commands cat /opt/cisco/esc/keepalived_state
ESC Health
ESC Service Status sudo escadm health
If you want to see more details (such as status of the
VIM manager, SNMP, portal, ESC manager, keepalived status and so on), add '–v': sudo escadm status --v
To check the detailed status, check the
/var/log/esc/escadm.log
Important Notes for ESC HA Active/Standby
• The HA Active/Standby failover takes about 2 to 5 minutes based on the number of managed VNFs to be operational. ESC service will not be available during the switchover time.
• When the switchover is triggered during transactions, all incomplete transactions will be dropped. The requests should be re-sent by Northbound interface if it does not receive any response from ESC.
Troubleshooting High Availability Active/Standby
• Check for network failures. If a network problem occurs, you must check the following details:
• The IP address assigned is correct, and is based on the OpenStack configuration.
• The gateway for each network interface must be pinged.

--libvirt --image <image_name> esc-vm --net <network> --ipaddr <ip_address>
Get a list of used IP addresses in your network. Use IP addresses that are not in the list for both HA
Active/Standby bootvm.py command and for kad_vip. Determine the first 3 octets of your network (i.e.
192.168.122) and pass it in the below command : arp -an | grep 192.168.122
To install ESC on a kernel-based VM in high availability, use the following command twice for both the HA nodes:
Note For the second bootvm.py command, use the other HA instance name.
./bootvm.py --user_pass <username>:<password> --user_confd_pass <username>:<password>
--libvirt --image <image_name> --ha_mode drbd --gateway_ip <default_gateway_ip_address>
--ipaddr <ip_address>
--ha_node_list <ha peer ip addresses separated by comma> --kad_vip <vip address> esc-ha-1
--net <network>

Installing Cisco Elastic Services Controller on a Kernel-based Virtual Machine (KVM)
Troubleshooting Tips
Procedure
Step 1
Step 2
Step 3
Check that the ESC VMs have booted using the following command:
$ virsh list
Get the IP address of the ESC VM, using the following command:
$ arp -an | grep <ip_address>
Connect to ESC using SSH and verify the processes are running:
$ ssh USERNAME@ESC_IP
Troubleshooting Tips
When SSH access is not available, due to network conditions or ESC startup failures, you can connect to ESC through console(if enabled in ESC VM image) or VNC access. To access ESC VM through VNC, do the following:
1.
Identify the vnc port.
virsh dumpxml 10 | fgrep vnc
2.
Create a ssh tunnel to the local vnc port to allow connection from your remote VNC client.

•
Installing the Elastic Services Controller Instance in AWS, on page 90
Prerequisites
Following are the prerequisites that you must complete before you start installing the ESC instance in AWS.
Note If the ESC AMI images are shared with your AWS account, you can ignore these prerequisites and directly use the AMI image for ESC installation.
Procedure
Step 1
Step 2
Step 3
Step 4
Configure AWS CLI . You can use pip to install AWS CLI. For more details, refer to the AWS documentation .
Configure the credentials for AWS CLI based on your account information.
Create a Amazon S3 Bucket. Use this for bucket for uploading ESC image.
Note You must have a role named vmimport that allows importing VM and you must attach an IAM policy to the role. For more information, refer to the documentation on the creation of S3 bucket in
AWS.
Extract the vmdk file from ESC ova file.
$ tar xvf ESC-<latest image file>.ova ESC-<latest image file>-disk1.vmdk

Installing the Elastic Services Controller Instance in AWS
Installing the Elastic Services Controller Instance in AWS
Once you have completed the tasks specified in the prerequisites section, you can use the procedure below to deploy and launch ESC instance in AWS.
Procedure
Step 1
Step 2
Upload and register ESC image.
a) Upload the vmdk image to the S3 bucket.
aws s3 cp <esc-vmdk-file> s3://<S3 bucket name>/ b) Register the image.
aws ec2 import-image --description "<esc-vmdk-file>" --disk-containers file://containers.json
Create user data .
a) Create a user for ESC VM. Without a user, you would not be able to access the VM. It is recommended to configure 'admin' user with sudo access and ssh key.
b) Create the esc-config.yaml in user-data using write_files command.
Each instance can have up to 15 interfaces, depending on the type of instances.
Note If you want to use two interfaces, ensure that you create the two network interfaces before hand.
These interfaces on different subnets must belong to the same availability zone. Add the interface details in the 'Configure Instance Details' tab when launching the instance from AWS console.
c) Enable esc_service and start it.
Following is an example of a complete user data:
#cloud-config
# It is recommended to disable password authentication for ssh when ESC runs in public cloud such as AWS.
ssh_pwauth: False users:
- name: admin
# Put admin in 'esc-user' group, otherwise some scripts of ESC might fail when running as admin.
groups: esc-user gecos: User created by cloud-init
# This is an example of the hashed password for 'admin'.

Cisco Elastic Services Controller 5.3 Install and Upgrade Guide
Installing Cisco Elastic Services Controller on Cisco Cloud Services Platform 2100
Installing the Elastic Services Controller Instance in CSP 2100
When using the Cloud-Init day0 file to deploy an ESC instance, the passwords must be passed in as a hash, and not a plain text.
To create a hashed password, use the mkpasswd tool. The following example shows how to use the mkpasswd tool to create a hashed password.
~$ mkpasswd --method=SHA-512 --rounds=4096
Password:
$6$rounds=4096$Yo11pRsFO$iT5SGMJ6z8WEnmj8TKMdInblgWeb/UChmrsQs3aspx8j.yUuuhxKk2XScOkerWWxpqD5F0sLfC5kzT5t2xGkL1
Procedure
Step 1
Step 2
Upload user-data file to CSP
To deploy ESC, the user-data file must be first uploaded to the CSP node.
Note The path to upload images and day0 files is: /osp/repository scp user-data-esc admin@<CSP_IP_ADDRESS>:/osp/repository
Deploying ESC VM
You must edit configuration to be sent to the CSP node hosting the ESC VM.
Following is the deployment datamodel for single interface. For dual interface, you have two interfaces.

Sending Configuration
Use a netconf-console (shipped with ConfD) to deploy ESC on a CSP node.
$ netconf-console --port=2022 --host=<CSP_IP_ADDRESS> --user=CSP_ADMIN_USERNAME
--password=CSP_ADMIN_PASSWORD --edit-config=deployESCHA1.xml
If HA, repeat the command with the configuration for the second ESC.
Configuring the VIM Connector
After ESC has booted, configure the VIM Connectors.
When installing ESC in CSP, no VIM connectors are added by default. To manage VNFs, you must create the VIM connector.
Adding the VIM Connectors
For more information on configuring VIM connectors after installation, and managing VIM connectors, see
Managing VIM Connectors in the Cisco Elastic Services Controller User Guide .
ESC HA Active/Standby Installation
To install ESC in CSP, you must create the user-data in the following format as the day0 configuration file.
For HA, you must define one file for each VM.
For creating ESC passwords to use in Day0 Files, see the Creating ESC passwords to use in Day0 Files section.
A sample for ESC HA Active/Standby installation on node 1 describing the day zero file as config drive and user data is as follows: user-data sample - HA Node 1
#cloud-config users:

Changing the ESC Password
You will be forced to change the default password on the first time login. Portal will not let you bypass this step and will keep returning you to this page until you change the default password. After the first time password change, you can change your password using the procedures described in this section. Also, if the user has multiple browsers or tabs or the SAME user is logged on by 2 or more computers and one of the user changes the password then everyone will be logged off and asked to re-enter the new password. The user session has an expiry of 1 hour so if the user is inactive on the portal for an hour then portal will expire the session and the user will have to re-login. If you forgot your password, you can also update or randomly generate the password.
This section discusses how to change the passwords.
Example for REST: sudo escadm rest set --username {USERNAME} --password {PASSWORD}
Example for ETSI: sudo escadm etsi set --rest_user {USERNAME:PASSWORD}

Creating Readonly User Group for ConfD in ESC
ConfD in ESC is enhanced with the introduction of a new group named readonly. If you are a member of readonly group, you can only retrieve the information and you cannot modify the permissions.
You can use 'readonly' as the role name with bootvm. The following example shows how to create two users in ConfD. One is admin and the other is readonly:
# bootvm.py name-500-105-100 --user_confd_pass admin:admin --user_confd_pass readonly:readonly::readonly --user_pass admin:admin --image ESC-5_0_0_105 --net network
For HA A/A, you can use 'readonly' as the group name in aa-day0.yaml Following is the example: confd: init_aaa_users:
- group: readonly name: admin passwd:
$6$rounds=4096$Ps1JIjKihRTF$fo8XPBxwEHJWWfNiXDnO269rlhAxAhWBcPBfGnZxy1gM3QMxcN8jJ6guWt9Bu.ZkWdPt3hr0OghO73Wr3iDHb0
You can also create a confd readonly user after ESC vm is deployed. The following steps create a confd readonly user named 'test' with password 'test':
[root@name-500-155 admin]# /opt/cisco/esc/confd/bin/confd_cli --user admin admin connected from 127.0.0.1 using console on name-500-155 admin@name-500-155> configure

ESC in ConfD sends access-denied error if you fall under readonly ConfD group, and require modify permissions. Following is the example of the access-denied error message:
$ esc_nc_cli --user readonly --password readonly edit-config dep.xml
Configure
/opt/cisco/esc/confd/bin/netconf-console --port=830 --host=127.0.0.1 --user=readonly

If ESC is configured to use PAM/IDM. The groups in IDM servers are directly mapped to the groups in
ConfD. Hence, the readonly user must be mapped in the IDM group 'readonly'.
For example:
$ ipa group-find --all readonly

Adding PAM User to an ESC Service/Component
Note • The SSHD service that runs inside the ESC VM already uses PAM authentication by default.
• If any component sets PAM authentication without specifying the PAM service, ESC defaults to the
PAM service 'system-auth'.
Adding PAM User to an ESC Service/Component
You can add the PAM user to the following groups of ESC service:
• rest-user
• confd-user
• portal-user
• etsi-user

Configuring Cisco Elastic Services Controller as the Identity Policy and Audit Client
• Ensure that the DNS server in ESC is in working state. So that, ESC interacts with the IDM server using the host name.
The following example shows how ESC (esc-client-500.linuxsysadmins.local) reaches the IDM server
(idmns.linuxsysadmins.local).
[root@esc-client-500 admin]# ping idmns
PING idmns.linuxsysadmins.local (192.168.222.176) 56(84) bytes of data.
64 bytes from idmns.linuxsysadmins.local (192.168.221.176): icmp_seq=1 ttl=64 time=0.492

64 bytes from idmns.linuxsysadmins.local (192.168.221.176): icmp_seq=2 ttl=64 time=0.457
ms
64 bytes from idmns.linuxsysadmins.local (192.168.221.176): icmp_seq=3 ttl=64 time=0.645
ms
You can configure IDM through sssd. ESC provides a PAM configuration file, point to
/etc/pam.d/syste-auth to system-auth-esc-sssd to start configuring services in ESC to work with the IDM server.
# cd /etc/pam.d
# ln -sf system-auth-esc-sssd system-auth
# ls -al /etc/pam.d/system-auth lrwxrwxrwx. 1 root root 20 Nov 13 00:39 /etc/pam.d/system-auth -> system-auth-esc-sssd

Authenticating REST Requests
ESC REST and ETSI REST APIs use http basic access authentication where the ESC client will have to provide a username and password when making REST requests. The user name and password will be encoded with Base64 in transit, but not encrypted or hashed. HTTPS will be used in conjunction with Basic
Authentication to provide the encryption.
This section discusses ESC REST and ETSI REST authentications, how to change the default password of the interfaces, and how to send an authorized requests from the ESC client.
REST Authentication
By default, the REST authentication is enabled. To disable REST authentication, you can pass the argument
--disable-rest-auth to bootvm. Cisco does not recommend you to use this in a production environment.
116
Cisco Elastic Services Controller 5.3 Install and Upgrade Guide
Post Installation Tasks
Enabling ETSI REST Authentication
ESC also supports https communication over port 8443. ESC will generate a self-signed certificate that the client will need to trust to get the https communication going. By default, REST is enabled as HTTP and restricted to localhost.
ESC can be installed with external access to REST on HTTPS or HTTP enabled with additional bootvm.py
arguments: -enable-https-rest or --enable-http-rest .
It is recommended to use only enabled external REST API when required. When enabled, it is recommended to use bootvm.py --enable-https-rest --user_rest_pass USERNAME:PASSWORD .
Note Make sure to pass either --enable-https-rest or --enable-http-etsi-rest or both the arguments to the bootvm.py
script to enable http and https interfaces to the REST API. You must pass --user_rest_pass while using either
--enable-https-rest or --enable-http-etsi-rest when REST authentication is not disabled. To enable https or http after ESC VM is booted, use the escadm command specified below.
sudo escadm escmanager set --url http://127.0.0.1:8080/ESCManager,https://0.0.0.0:8443/ESCManager
You must change the configuration of the peer instance if ESC is in HA Active/Standby mode.
Enabling ETSI REST Authentication
If the ETSI REST http or https interfaces are enabled, then all requests to an ETSI API must contain authentication data. You can use the --enable-http-etsi-rest or --enable-https-etsi arguments respectively to enable http and https interfaces to the ESC bootvm.py installation script.
You can enable both interfaces simultaneously, but only the https interface should be enabled in a production environment.
Note To enable http or https after the ESC VM has booted, use the escadm command specified below: sudo escadm etsi enable_http_rest
OR sudo escadm etsi enable_https_rest
Then restart the ETSI service.
Changing the REST Interface Password
The REST interface has only one default username/password (admin/<default_password>). The password can be updated after the bootup using escadm tool from the ESC VM CLI. You can also update the password through the REST API.
Procedure
Step 1
Step 2
Log in to ESC VM.
To replace the existing password with a new one, use one of the below options:
• Using the escadm tool from the ESC VM CLI, you can generate a random password:

Changing the ETSI REST Interface Password
[root@test-v44-52 admin]# escadm rest set --help usage: escadm rest set [-h] [-v] --username USERNAME [--password PASSWORD] optional arguments:
-h, --help show this help message and exit
-v, --v, --verbose show verbose output
--username USERNAME
--password PASSWORD new password or use randomly generated password if no password provided
• Using the REST API: http://[ESCVM_IP]:8080/ESCManager/v0/authentication/setpassword?userName=admin&password=yourPassword or https://[ESCVM_IP]:8443/ESCManager/v0/authentication/setpassword?userName=admin&password=yourPassword
Changing the ETSI REST Interface Password
The ETSI REST interface has only one default username/password (admin/<default_password>). The password can be updated after the bootup using escadm tool from the ESC VM CLI.
Procedure
Step 1
Step 2
Log in to ESC VM.
To set the default ETSI REST username and password, use the following command: sudo escadm etsi set --rest_user username:password or
[admin@xyz-esc-4-4-0-59-keep ~]$ escadm etsi set --help usage: escadm etsi set [-h] [-v] [--startup {0,1,true,false,manual,auto}]
[--rest_user REST_USER] [--pam_service PAM_SERVICE] optional arguments:
-h, --help show this help message and exit
-v, --v, --verbose show verbose output
--startup {0,1,true,false,manual,auto} set to false|0|manual to disable etsi at startup.
--rest_user REST_USER
Set the user for rest. Format username:password
--pam_service PAM_SERVICE
Specify a PAM service to use for authentication. This will override the rest user. To revert to the using the rest user for authentication, supply an empty string.
Sending an Authorized REST Request
To send an authorized request, the ESC client should send the request with the following header:
Authorization: Basic YWRtaW46Y2lzY28xMjM=
118
Cisco Elastic Services Controller 5.3 Install and Upgrade Guide
Post Installation Tasks
Sending an Authorized ETSI REST Request where YWRtaW46Y2lzY28xMjM= is the Base64 encoded string of the default username/password.
Most libraries and web clients have an interface for providing the username/password and the application will encode the username/password and add the HTTP Basic Auth header.
Example using the default credentials:
For HTTP: http://[ESCVM_IP]:8080/ESCManager/v0/tenants/
For HTTPS: https://[ESCVM_IP]:8443/ESCManager/v0/tenants/
Sending an Authorized ETSI REST Request
To send an authorized request, the ESC client should send the request with the following header:
Authorization: Basic YWRtaW46Y2lzY28xMjM= where YWRtaW46Y2lzY28xMjM= is the Base64 encoded string of the default username/password.
Most libraries and web clients have an interface for providing the username/password and the application will encode the username/password and add the HTTP Basic Auth header.
Example using the default credentials:
For HTTP: http://[ESCVM_IP]:8250/vnflcm/v1/vnf_lcm_op_occs
For HTTPS: http://[ESCVM_IP]:8251/vnflcm/v1/vnf_lcm_op_occs
Configuring Openstack Credentials
If ESC was deployed without passing VIM credentials, you can set VIM credentials through ESC VIM and through VIM User APIs (REST or Netconf API ).
Note ESC will accept the northbound configuration request only if the following conditions are met:
• ESC has VIM or a VIM user configured through APIs(REST/Netconf).
• ESC has VIM or a VIM user configured, and ESC is able to reach the VIM.
• ESC has VIM or a VIM user configured, and ESC is able to authenticate the user.
Configuring using Netconf API
• Passing VIM credential using Netconf :

Configuring Openstack Credentials
Note • From ESC 3.0 onwards, multiple VIM connectors are supported but within one ESC, only one type of VIM are supported. For example, all the Vim
Connector(s) has to be for OpenStack only. One ESC VIM cannot have two
VIM connector, one points to OpenStack, one points to VMware.
• One VIM is chosen as the default VIM which supports all pre 3.0 config requests and datamodels.
• Deployments can be done on the VIM that is not the default VIM. The deployment to a non default VIM has to have all out-of-band resources
(except ephemeral volumes). No other configurations like image, flavor, network, and so on can be done on the VIM that is not the default VIM.
• The default VIM connector will be auto provisioned and does not need to be configured in the following scenarios:
• If VIM credentials have been passed during ESC boot up.
• If upgrading from 2.3.x to 3.0.
• The change in the datamodel for Openstack create VIM connector would be handled during upgrade by migration. The 'os_tenant_name' and
'os_project_domain_name' properties would be moved to the VIM Connector properties and 'os_ternant_name' will be renamed to 'os_project_name'.
• For the default VIM Connector, once it is properly authenticated, its properties cannot be updated.
• VIM user can be deleted, recreated, or its properties can be updated at anytime.
• Updating VIM Connector using Netconf:

Reconfiguring ESC Virtual Machine
• VIM username and password can be updated at anytime. VIM endpoint will not be able to update after a resource is created through ESC.
• After VIM is connected and VIM user is authenticated, VIM can no longer be deleted or updated, only VIM user can be deleted or updated.
• The name of a VIM property or VIM user credentials property is not case sensitive, e.g.
OS_AUTH_URL and os_auth_url is the same to ESC.
Reconfiguring ESC Virtual Machine
This section covers the following:
• Reconfiguring Rsyslog
• Reconfiguring NTP
• Reconfiguring DNS
• Reconfiguring Hosts
• Reconfiguring Timezone
Reconfiguring Rsyslog
Rsyslog parameters are optional. If there is a need for customization after booting an ESC VM, you can edit the files in ESC VM (/etc/rsyslog.d/).
Procedure
Step 1 Editing the Rsyslog file :
• If you haven't specified the log forwarding configuration at the bootup time, you may create a file under
/etc/rsyslog.d/ like /etc/rsyslog.d/log-forwarding.conf.
• If you have specified the log forwarding through installation, you may just need to edit the file. The file could be /etc/rsyslog.d/20-cloud-config.conf. In this file, to forward logs to multiple rsyslog servers, edit the following line:
*.* @[server_ip]:port
Note • Use '@@' before specifying server ip address (if TCP is the protocol used to forward logs to the rsyslog server).
• Use '@' before specifying server ip address (if UDP is the protocol used to forward logs to the rsyslog server).
• server_ip can either be ipv4/ipv6 address of the rsyslog server.
• '[ ]' around the server_ip is required to separate it from ' :port# ', if an ipv6 server address is specified.
For further information on Rsyslog configuration, see the Red Hat documentation.

Post Installation Tasks
Reconfiguring NTP
Step 2
Step 3
Step 4
Configuring the ESC log file: Configure which ESC log files you want to forward to the rsyslog server: a) Navigate to /etc/rsyslog.d/ Create or modify a configuration file, such as log-esc.conf
. Make a copy of sample log-esc.conf .
b) Specify the following block for every file you want to forward to rsyslog server.
$InputFileName /var/log/esc/escmanager.log
$InputFileTag esc-manager:
$InputFileStateFile stat-esc-manager
$InputFileSeverity info
$InputRunFileMonitor
For example:
$InputFileName /var/log/esc/file1.log
$InputFileTag file1:
$InputFileStateFile stat-file1
$InputFileSeverity info
$InputRunFileMonitor
$InputFileName /var/log/esc/file2.log
$InputFileTag file2:
$InputFileStateFile stat-file2
$InputFileSeverity info
$InputRunFileMonitor
Restart the rsyslog service
# service rsyslog restart
Configure the server side to receive forwarded logs.
a) On a designated server, go to /etc/rsyslog.conf, and uncomment the lines shown below, depending on if you want to listen to logs from clients based on TCP or UDP:
#$ModLoad imudp
#$UDPServerRun 514 b) Exit the file. Run this command as the last step.
sudo service rsyslog restart
Now, the server is listening for logs on port 514, using TCP/UDP.
Reconfiguring NTP
Procedure
Step 1
Step 2
Open the NTP configuration file /etc/ntp.conf in a text editor such as vi, or create a new one if it does not already exist:
# vi /etc/ntp.conf
Add or edit the list of public NTP servers. If you don't specify the NTP server through the installation, the file should contain the following default lines, but feel free to change or expand these according to your needs:

Reconfiguring DNS
Step 3
Step 4
Step 5 server 0.rhel.pool.ntp.org iburst server 1.rhel.pool.ntp.org iburst server 2.rhel.pool.ntp.org iburst server 3.rhel.pool.ntp.org iburst server <your_ntp_server_ip> iburst
The iburst directive at the end of each line speeds up the initial synchronization.
Once you have the list of servers complete, in the same file, set the proper permissions, giving the unrestricted access to localhost only. Make sure those lines are there in your configure file.
restrict default kod nomodify notrap nopeer noquery restrict -6 default kod nomodify notrap nopeer noquery restrict 127.0.0.1
restrict -6 ::1
Save all changes, exit the editor, and restart the NTP daemon:
# service ntpd restart
Make sure that ntpd is started at boot time:
# chkconfig ntpd on
Reconfiguring DNS
Procedure
Step 1
Step 2
Step 3
The /etc/resolv.conf file contains the configuration for the DNS client (resolver). It typically looks something like this: search domain.com
nameserver 8.8.4.4
This results in a
/etc/resolv.conf
:
Created by cloud-init on instance boot automatically, do not edit.
;
#Generated by esc-cloud domain cisco.com
search cisco.com
nameserver 8.8.4.4
Note It is recommended that you ignore the do not edit message, if you want to modify the file.
You may modify the IP address of the "nameserver" item or add new nameserver records.
search domain.com
nameserver <your_first_dns_ip> nameserver <your_second_dns_ip>
Restart Network Service.

Reconfiguring Hosts
Reconfiguring Hosts
The /etc/hosts file allows you to add, edit, or remove hosts . This file contains IP addresses and their corresponding hostnames. If your network contains computers whose IP addresses are not listed in DNS, it is recommended that you add them to the /etc/hosts file.
Procedure
Step 1
Step 2
Add the IP addresses that are not listed in DNS to the /etc/hosts file.
Restart your network for the changes to take effect.
service network restart
Reconfiguring Timezone
For ESC VM, in /etc the file "localtime" is a link to or copy of a file containing information about your time zone. Access your zone information files from /usr/share/zoneinfo. To change the time zone, find your country, your city or a city in the same time zone from zone information files in /usr/share/zoneinfo and link it to the localtime in the /etc file.
$ ln \-sf /usr/share/zoneinfo/America/Los_Angeles /etc/localtime

Setting ESC in a Maintenance Mode
ESC must be put to maintenance mode to backup and restore ESC database. To do so, use the escadm tool as specified in the below section.
Before you begin
Note From ESC release 4.4, ESC continues to be in maintenance mode after HA Active/Standby switch over or
DB restoration, if ESC was in maintenance mode before HA Active/Standby switch over or DB restoration.
During maintenance mode,
• Northbound requests are blocked by ESC and ESC responds with maintenance mode notification.
• Only REST requests receive response that ESC is unavailable temporarily. ConfD requests get the maintenance mode rejection message, or an OK message for all idempotent request such as create tenant request when the tenant already exists.
• Monitoring actions are paused.
• All ongoing requests and transactions continue to progress.
Using the escadm Tool
ESC can be put to maintenance mode using the escadm tool.

Setting ESC in an Operation Mode
Procedure
Step 1
Step 2
Step 3
Put ESC to maintenance mode from the VM shell: sudo escadm op_mode set --mode=maintenance
Set mode to MAINTENANCE
Operation Mode = MAINTENANCE
If you have D-MONA deployed, do the following to each D-MONA: curl -i -k --user {REST username}:{REST password} -X POST https:/{DMONA
IP}:8443/mona/v1/rules/pause_all
To query operation mode at any time, sudo escadm op_mode show
Example:
Operation Mode = OPERATION
Set maintenance mode when there is no in-flight transaction. Using the ipt_check flag with the escadm tool, you can choose to set ESC in the maintenance mode only if there are no ongoing transactions in ESC. Set the flag to true, if you do not want ESC to set in the maintenance mode, if there are ongoing transactions in ESC.
sudo escadm op_mode set --mode=maintenace --ipt_check=true
With the ipt_check option set to true, escadm tool checks if there is any on going operation, if so, the escadm tool will not set ESC to maintenance mode.
Note ESC with D-MONA deployment, requires to do extra calls when going to maintenance mode.
Setting ESC in an Operation Mode
Put ESC in operation mode using the escadm tool: sudo escadm op_mode set --mode=operation
Response is as follows:
Set mode to OPERATION
Operation Mode = OPERATION
If you have D-MONA deployed, do the following to each D-MONA: curl -i -k --user {REST username}:{REST password} -X POST https:/{DMONA
IP}:8443/mona/v1/rules/resume_all
Verify ESC's operation mode at any time using the following command: sudo escadm op_mode show
Backup the Database from the ESC Standalone Instances
• The following assumptions should be taken into consideration :
• A third machine is required to store the database and log backups.
136
Cisco Elastic Services Controller 5.3 Install and Upgrade Guide
Upgrading Cisco Elastic Services Controller
Backup the Database from the ESC Standalone Instances
• ESC does not support database schema downgrade. Restoring database to the older ESC version could cause unexpected problems.
• Before you start the backup process, ensure you have an external storage space (could be in the OpenStack controller or any system accessible by ESC). The backup/restore could be expressed in a generic format which will be used by the escadm tool: scp://<username>:<password>@<backup_ip>:<filename> . In this format, the credentials, IP address and file storage path of the third machine are required. You may also use localhost IP as the backup IP to backup database in a location of ESC VM and then copy the files to the external storage
To backup the ESC database from a standalone ESC or a HA Active/Standby (master node):

To make sure ESC is in maintenance mode, run:
$ sudo escadm op_mode show
Backup database. Execute the commands below as a root user:
# sudo escadm backup --file /tmp/db_file_name.tar.bz2
scp://<username>:<password>@<backup_vm_ip>:<filename>
To put ESC back to operation mode, run:
$ sudo escadm op_mode set --mode=operation
$ sudo escadm op_mode show
Collect all the logs from the old ESC VM and back it up. Execute the below command as a root user.
# sudo escadm log collect
A timestamped log file will be generated in: /var/tmp/esc_log <timestamp>.tar.bz2
Note If a dynamic mapping file is used by ESC service, the dynamic mapping file should be backed up at the same time with ESC logs. The default path of the dynamic mapping file is
/opt/cisco/esc/esc-dynamic-mapping/dynamic_mappings.xml.
After a successful database back-up, shut down the old ESC VM using Horizon/Kilo or Nova commands. For
ESC VM instances based in VMware vSphere, shutdown the primary instance through VMware client dashboard. An example of shutting down a VM in OpenStack is shown below :
$ nova stop OLD_ESC_ID
Detach the old port from the old VM and rename the old ESC node. Examples of detaching and renaming the
VM in OpenStack is shown below: nova interface-detach ESC_NAME port-id-of-ESC_NAME nova rename ESC_NAME ESC_NAME.old

BackuptheDatabase fromtheESCHAActive/Standby Instances
• The following assumptions should be taken into consideration :
• A third machine is required to store the database and log backups.
• ESC does not support database schema downgrade. Restoring database to the older ESC version could cause unexpected problems.
• Before you start the backup process, ensure you have an external storage space available (could be in the OpenStack controller or any system accessable by ESC). The backup/restore could be expressed in a generic format which will be used by the escadm tool: scp://<username>:<password>@<backup_ip>:<filename> . In this format, the credentials, IP address and file storage path of the third machine are required. You may also use localhost IP as the backup IP to backup database in a location of ESC VM and then copy the files to the external storage.
To backup the ESC database from a standalone ESC or a HA Active/Standby (master node):
Procedure
Step 1
Step 2
Perform the following steps on the Standby ESC node.
a) Connect to the standby ESC instance using SSH:
$ ssh <username>@<backup_vm_ip> b) Verify that the ESC instance is standby and note the name of the standby ESC HA Active/Standby instance
:
$ sudo escadm status --v
If the output value shows "BACKUP", the node is the standby ESC node.
c) Change access to an admin user.
sudo bash d) Collect all the logs from the standby ESC VM and back it up.
$ sudo escadm log collect
A timestamped log file will be generated in: /var/tmp/esc_log <timestamp>.tar.bz2
e) Shutdown the standby ESC instance through OpenStack Kilo/Horizon using Nova command or VMware client. An example of shutting down the VM on OpenStack is shown below:
$ nova stop OLD_ESC_STANDBY_ID
Perform the following steps on the Master ESC node.
a) Connect to the primary ESC instance using SSH:

Step 4
$ ssh <username>@<master_vm_ip> b) Change access to an admin user.
$ sudo bash c) Verify that the ESC instance is Master and note the name of the Master ESC HA Active/Standby instance
$ sudo escadm status --v
If the output value shows "MASTER", the node is the Primary ESC node.
d) Back up the database files from the master node of ESC HA Active/Standby:
$ sudo escadm backup --file /tmp/db_file_name.tar.bz2
scp://<username>:<password>@<backup_vm_ip>:<filename> e) Collect the logs from the master ESC VM and back it up.
$ sudo escadm log collect
A timestamped log file will be generated in: /var/tmp/esc_log <timestamp>.tar.bz2
Note If a dynamic mapping file is used by ESC service, the dynamic mapping file should be backed up at the same time with ESC logs. The default path of the dynamic mapping file is
/opt/cisco/esc/esc-dynamic-mapping/dynamic_mappings.xml
.
Shutdown the primary ESC instance through OpenStack Kilo/Horizon using Nova command. For ESC VM instances based in VMware vSphere, shutdown the primary instance through VMware client dashboard. An example of shutting down the VM on OpenStack is shown below:
$ nova stop OLD_ESC_MASTER
Use the nova list command or the nova show OLD_ESC_STANDBY command, to verify if the ESC HA
Active/Standby instances have been successfully shut down.
(Only for OpenStack) Detach the port from the old ESC VM and rename the old VM.
If upgraded ESC VM needs to operate with same IP addresses and same instance names as old instances, detach the ports from each instance, shutdown the old ESC VMs and then rename the old ESC instances.
If you intend to use old VMware primary instance, assign a different IP address and rename the VM name.
If not, you can delete the old VM and use the same IP address for the new upgraded VMware primary instance.
After deleting the old VM, you can continue with the old instance name and the IP address.
OpenStack commands for detaching the ports and renaming the old VMs are shown below: nova interface-list ESC_NAME nova interface-detach ESC_NAME port-id-of-ESC_NAME nova rename ESC_NAME ESC_NAME.old

Restoring ESC Database
Restoring ESC Database
Before you begin
To restore the database,
• In standalone ESC instance, stop ESC services. Run
# sudo escadm stop
.
• In HA Active/Standby type instances, stop escadm on the Backup first, and later on the Master ESC HA
Active/Standby instance. Run
# sudo escadm stop
.
• All the services must be stopped. To check the status, run
# sudo escadm status --v
.
Procedure
Step 1
Step 2
Step 3
Restore the database. Execute the following command from the ESC VM:
$ scp <username>@<server_ip>:/path/db.tar.bz2
$ sudo escadm restore –file /tmp/db.tar.bz2
/tmp/
Enter the ESC password in the URL, or manually enter it after executing the above command.
Restart the ESC service to complete the database restore by running the following command:
$ sudo escadm restart
Note ESC maintenance mode blocks the northbound request and VNF monitoring. However, if there are some ongoing transactions because of northbound requests before ESC entering maintenance mode, those transactions may have following restriction with backup and restore:
• ESC reports an error for the deployment, network creation, and subnet creation requests, if these transactions are interrupted by backup and restore. Northbound handles these error messages but it may cause network or subnet leakage in some cases (For example, ESC is interrupted before getting the UUID from OpenStack).
• ESC reports an error for service chain upgrade, and requires service chain undeployment and deployment (rather than downgrade and upgrade) to re-create the service.

Upgrading Cisco Elastic Services Controller
Cisco Elastic Service Controller supports two type of upgrades:
• Backup and Restore Upgrade : This upgrade process involves stopping the ESC keepalive daemon (for
ESC HA), backing up the database, stopping and renaming (or deleting) the ESC instances, re-installing the ESC instances, and restore database. For information on the supported ESC versions for ESC 5.3
upgrade, see the table below.
• In-service upgrade : ESC supports in-service upgrade for Active/Standby high availability nodes with a minimum downtime.
You can upgrade the ESC instance as a standalone instance or as a high availability pair. The upgrade procedure is different for standalone and high availability pair.
This chapter lists separate procedures on how to upgrade ESC standalone and ESC High Availability instance.
You must review these instructions before you decide to upgrade the ESC instance. See the
for more information on the installation scenarios.
• ESC only support direct upgrade from previous two minor releases. For example, ESC 2.3 will support direct upgrade from ESC 2.1 and ESC 2.2. For any release older than the supported versions for direct upgrade, you need to perform the staged upgrade.
Note Example of an ESC major release, ESC 3.1
Example of an ESC minor release, ESC 3.1.1
Example of an ESC patch release, ESC 3.1.0.116.
• Upgrading ESC using RPM Package (referred to as RPM Upgrade in this chapter) applies only to the
ESC upgrade between ESC patch releases with the same release number. For Example, the upgrade from
ESC 3.1.0.116 to ESC 3.1.0.150.
• If you want to upgrade ESC between minor releases (for example, upgrade from ESC 2.3.1 to ESC
2.3.2) or major releases (for example, upgrade from ESC 3.0 to ESC 4.0 ), you can upgrade through
Backup and Restore upgrade process using qcow2 image.
• For ESC upgrade, you should be familiar with ESC installation process.
• For OpenStack, refer to the OpenStack installation procedures, see Chapter 4: Installing Cisco Elastic
Services Controller in OpenStack.
• For VMware, refer to the VMware Installation installation procedures, see Chapter 7: Installing
Cisco Elastic Services Controller in VMware vCenter.

IMPORTANT NOTES
• After upgrading to the new ESC version, ESC service will manage the life cycle of all VNFs deployed in the previous release. To apply any new features (with new data models) to the existing VNFs, you must undeploy and redeploy these VNFs.
• Upgrade is supported for Active/Active HA only.
Note Do not change the VIP in ESC upgrade in ETSI deployment.
If you change ETSI's REST schema, from http to https in-flight, ESC stops sending recovery notification from
ESC core for any existing deployment.

Restore the ESC database on the new ESC instance. For more information, see the below section, Restoring the ESC Database .
Deploy the ESC for Upgrade
After backing up and shutting down of the old ESC VM, a new/upgraded (based on new ESC package) ESC
VM should be installed. All parameters for ESC installation should be the same as the old ESC VM deployment.
• For OpenStack, you need to register the new ESC qcow2 image using the Glance command with a new image name and then use new bootvm.py script and new image name to install ESC VM.
Note In OpenStack, if an old ESC VM was assigned with floating IP, the new ESC
VM should be associated with the same floating IP after the installation.
• For VMWare, you need to use the new ESC OVA file to install ESC VM. All other configurations and property values should be the same as the old VM.
Restoring the ESC Database
Restore the ESC database on the new ESC instance , using the following procedure:
Procedure
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
Connect to the new ESC instance using SSH.

Important Notes:
Important Notes:
After upgrading to the new ESC version, ESC service will keep doing life cycle management of all VNFs deployed by the old version. However, to apply any new features (with new data models) to the VNFs deployed by the ESC with old version is not guaranteed. If you want to apply any new feature of the new ESC version to existing VNFs, you have to undeploy and redeploy those VNFs.
Upgrading ESC HA Active/Standby Instances
To upgrade ESC HA Active/Standby nodes, perform the following tasks:
1.
Back up the database from an old ESC HA Active/Standby primary instance. For more information, see
Backup the Database from the ESC HA Active/Standby Instances .
Note To backup any custom scripts used by the deployments, and for restoring them before restoring the database, you must copy the scripts on the backup as well.
2.
Deploy new ESC HA Active/Standby nodes based on new ESC version. For more information, see the below section, Deploy the ESC HA Active/Standby nodes for Upgrade .
3.
Restore the Database on Primary ESC instance (Standby ESC instance will sync with the Primary ESC instance ). For more information, see the below section, Restoring the ESC Database on New Master and Standby Instances .
Deploying the ESC HA Active/Standby nodes for Upgrade
After backing up and shutting down the two old ESC VMs, based on new ESC package install the new ESC
VMs.
• For OpenStack, you need to register the new ESC qcow2 image using the Glance command with a new image name and then to use new bootvm.py script and new image name to install ESC VM. All other bootvm.py arguments should be the same as used to setup an old VMs.
• For VMWare, there are two steps to bring up HA Active/Standby pair in VMware: 1) setup two standalone instances 2) reconfigure each instance with HA Active/Standby info. All other configurations and property values should be the same as the old VMs.
• If VIP is used for Northbound access, keep VIP the same for the new deployment as used to reconfigure the old HA Active/Standby pair.

In-Service Upgrade of the ESC HA Active/Standby Nodes in CSP
Follow the steps to do the In Service upgrade of the ESC HA Active/Standby Nodes in CSP:
Before you begin
Verify that the ESC HA nodes running properly before the upgrade, by using the following command:
# escadm status
One node must be in Master state and the other node in Backup state. Verify the Master node by using the following command:
# health.sh
On a successful health check you receive the following:
ESC HEALTH PASSED
Procedure
Step 1
Step 2
Shutdown the Standby instance
Upgrade the Backup ESC VM, before power off the VM. To upgrade, follow the steps: a.
Collect the logs from the Backup ESC VM, and copy it to another machine, by using the following commands:
# collect_esc_log.sh
# scp /tmp/LOG_PACKAGE_NAME <username>@<backup_vm_ip>:<filepath> b.
Using CSP, power off the standby ESC.
Deploy the standby node again using the new ESC package
After power off the standby ESC VM, install new ESC VM for upgrading by using the new ESC package.
Except using different ESC packages from the former ESC VM, all other parameters for ESC installation must be the same as the previous ESC VM deployment.
Verify that the ESC node is in Backup state. Use the following command to check the synchronization state of the new ESC standby node:

172.20.117.55:7789 role:Primary peer-disk:UpToDate
If a dynamic mapping file (dynamic_mapping.xm) is used by ESC service, it must be restored into the ESC
VM. Copy the Backup file to
/opt/cisco/esc-dynamic-mapping/ path.
Stop the Master node and trigger a switchover.
Power off the Master instance through CSP. Follows that, an HA switchover automatically triggers and the
Standby instance takes over the ESC service with the new ESC version. After new ESC instance becomes the
Master, verify that the new ESC Master node passes the health check.
Deploy new ESC node to replace old Master
Install the new ESC VM for upgrading the previous Master instance by using the new ESC package. Before powering off the ESC VM with the old version, collect the logs from the ESC VM, and copy it to another machine by using the following commands:
# collect_esc_log.sh
# scp /tmp/LOG_PACKAGE_NAME <username>@<backup_vm_ip>:<filepath>
Note If a dynamic mapping file is used by ESC service, the dynamic mapping file should be backed up at the same time with ESC logs. The default path of the dynamic mapping file is
/opt/cisco/esc/esc-dynamic-mapping/dynamic_mappings.xml.
Power off the ESC VM with old version through CSP.
Verify that the ESC node is in Backup state. Use the following command to check the synchronization state of the new ESC standby node:
# drbdadm status
Wait until you get the following output, which shows that the new ESC VM has completed the data synchronization from the Master node and it is up to date.

172.20.117.55:7789 role:Primary peer-disk:UpToDate
If a dynamic mapping file (dynamic_mapping.xm) is used by ESC service, it must be restored into the ESC
VM. Copy the Backup file to
/opt/cisco/esc-dynamic-mapping/ path.
Note If a dynamic mapping file is used by ESC service, the dynamic mapping file should be restored into the ESC VM. Copy the backup dynamic mapping file to the default path of the dynamic mapping file
/opt/cisco/esc/esc-dynamic-mapping/dynamic_mappings.xml.
Once you sucessfully complete the in-service upgrade, you can remove the old ESC instance.

Viewing ESC Log Messages
Log messages are created for ESC events throughout the VNF lifecycle. These can be external messages, messages from ESC to other external systems, error messages, warnings, events, failures and so on. The log file can be found at /var/log/esc/escmanager_tagged.log
.
The log message format is as follows: date=<time-date>] [loglevel=<loglevel>] [tid=<transactionid>] [cl=<classifications>]
[tags=<tags>] [msg=<message>
Sample log is as follows: date=15:43:58,46022-Nov-2016]
[loglevel=ERROR ] [tid=0793b5c9-8255-47f3-81e6-fbb59f6571f7] [cl=OS ]

When a request is received, a RequestDetails object is created which autogenerates a unique transaction id.
This value is carried forward across all threads. Classifications and tags are optional. These are prefixes added to the log messages to enhance readability, and help in debugging. With classifications and tags, the log messages can be easily parsed and filtered by the log analysis tools.
The following classifications are supported:
NBI
SBI
"com.cisco.esc.rest""com.cisco.esc.filter"(North Bound Interface -
Clientinterface)
"com.cisco.esc.rest"- source is a callback handler or"EventsResource"(South

The parameters for log level, classification and tags are dependent on each other to retrieve the logs. You can successfully retrieve the logs with the following combination.
• log_level=ERROR, classifications=OS, tags=(depName:test-dep)
• log_level=ERROR, classifications=OS, tags=(tenant: test)
The log filter returns a value when all the following conditions are met:

• Check the log /var/log/esc/escadm.log
$ cat /var/log/esc/escadm.log
• Add '-v' to escadm status to show the verbose output of the ESC services and see the services are up and running.
2.
Confirm the status of the identified services that has issues and manually start these services.
$ sudo escadm <<service>> status//
If the status is stopped or dead, manually start the services using the next command.
$ sudo escadm <<service>> start --v

General Installation Errors
Problem/Error Possible Reason User Action
ESC master node stays in the
"switching-to-master" state
This could be because of the following issues:
Check for the:
• ESC HA
Active/Standby node can not reach its peer during the initial installation.
• Connectivity between ESC master node and standby node. For initial installation, ESC master service won't be up if it can't reach the standby node. You need to make sure you have both ESC nodes successfully deployed and they can reach each other.
• ESC logs at /var/log/esc/esc_haagent.log (ESC 2.X) or /var/log/esc/escadm.log (ESC 3.X) to identify the services that has issues.
• ESC service
(tomcat) can't start properly due to database problems
(etc. database migration, database file corruption).
• Log at /var/log/esc/escmanager.log for esc_service and postgresql issues.
• Confd can't start due to the CDB file corruption.
• Postgresql can't start or init due to the file system issues.
• The connection between ESC nodes is too slow.
MTU issues for ESC
HA Active/Standby
For the ESC VMs, reduce the MTU for network interfaces from 1500 to 1450. Follow the below steps to reduce the
MTU value:
1.
Identify the interface you would like to change. Access the interface from the location,
/etc/sysconfig/network-scripts/ifcfg-ethX, where X represent the interface number you want to change.
2.
Use a text editor like VIM to add or edit the MTU items for the interface, for instance, set MTU = 1450
3.
Restart the interface.

• Keepalived log is located at /var/log/messages by grep keepalived or vrrp
• For DRBD configuration:
• DRBD configuration can be verified by checking the file at /etc/drbd.d/esc.res
• The DRBD log is located at /var/log/messages by grep drbd
ESC Services Startup Issues
Service status reports
ETSI service is dead at installation time using sudo escadm status --v
If the host has multiple
IP addresses the ETSI service is unable to determine which IP address to use when generating callback
URLs.
This cause can be verified by examining the log file
/var/log/esc/etsi-vnfm/etsi-vnfm.log
for an exception including:

ESC Failover Scenarios
• When customer deploys many VNFs
Cisco Elastic Services Controller 5.3 Install and Upgrade Guide
171
ESC Failover Scenarios
Troubleshooting Cisco Elastic Services Controller Installation
• When customer does a DB backup
• 1 or more of the VMs in the VNFs is recovered via redeploy – new VM ID
• ESC Fails – It is a permanent failure
• Customer Restores DB – When there is a mismatch between 1 or more VM IDs
• Same VNF fails, but when ESC tries to recover, it fails because it is not found on the VIM by VM ID and redeploy fails because the ports are in use.
• The workaround is to delete the VM out of band and recover – if the VM is deleted it is not found by
ESC and the port is available for redeployment.

Arguments
--user_pass
Description
This along with --user_confd_pass are mandatory arguments from 3.0
onwards.
This argument adds a user to access the ESC VM. Use this argument to specify a user without administrative privileges, i.e, a non-admin/non-root user. Use the following format: user_name:password. The bootvm.py command requires at least one
--user_pass argument to create an admin account for linux (ssh/console access) . The following is the syntax for the mandatory user credential argument:
--user_pass admin:'PASSWORD-OR-HASH'[:OPTIONAL-PUBLIC-KEY-FILE][:OPTIONAL-ROLE]
This user can only do the following:
• Login to ESC through SSH.
• Access and drive the Netconf CLI, such as, esc_nc_cli, netconf-console, and so on.
• Read ESC -related logs from /var/logs/esc
• Access REST interface through localhost
This user cannot:
• Access the ESC DB and reconfigure ESC system.
• Access the system-level logs
• Configure the system level components, such as: Rsyslog,
Keepalived, DRDB, and so on.
• Access the encryption keys and values from REST interface or
ESC logs.
Following is an example of --user_pass for admin account and stronger clear text passwords. Use single quotes to avoid conflict with shell reserved characters:
-user_pass admin:'Strong4Security!'.
Another example to install ESC using a password hash for both admin accounts. Use single quotes to avoid conflict with shell reserved characters:
--user_pass admin:'$algorithm$salt$hash-of-salt-password'.
ESC 2.1 and later, accepts the public key for this attribute. For example, the following will generate 'admin321' as the password for user 'admin' and use /tmp/abc.pub
as the key file to inject the public key for it:
--user_pass admin:admin321:/tmp/abc.pub
