This document guides you through the installation, setup, and deployment of the Active Fabric Controller
(AFC) software on a single server or on two servers in an active-standby configuration.
NOTE: You can install the software on a single server. For resiliency, Dell Networking recommends
configuring a dual-server setup for high availability (HA).
Install the software using the route processor module (RPM) or the open virtualization format (OVF)
image. Installation scripts, including RPM-based scripts for components, such as the database service,
software controller, and web-based graphical user interface (GUI) are used during installation.
System Requirements
Each server can be a virtual machine (VM) or a physical machine. The server or virtual machine
requirements are:
•
CPU — 2.4 GHz, Intel Xeon CPU or equivalent. For optimal performance, Dell Networking
recommends a four-core as a minimum.
•
Memory — 8 GB
•
Disk space — 30 GB
•
Network Interface — 1x1 GbE
•
CentOS 6.4, 64–bit (for RPM installation)
•
ESX 4.x or 5.x server (for OVF installation)
•
MongoDB
•
Link layer discovery protocol (LLDP) enabled on all hosts and servers
Recommended Requirements
The following components are not required to run the software, but are recommended to provide
additional capabilities:
•
Dell OpenFlow-compatible switches
•
A second server for HA configuration to provide resiliency
•
Enabling bare metal provisioning (BMP) updates the firmware on the switches automatically. To
enable BMP, the switches and the controller must be in the same Layer2 (L2) network. Also, the
location of the image and the primary boot location must be the same.
Introduction

Pre-Installation Procedure
Before installing the software, perform the following pre-installation steps:
1.
Prepare the infrastructure networks.
Infrastructure networks support management of the physical infrastructure by the software. A typical
OpenStack environment requires two infrastructure networks: a storage network and an OOB
network. You can implement these networks as two separate physical L2 networks or as virtual local
area networks (VLANs) on the same physical L2 network. Typically, servers in an OpenStack
environment connect to both infrastructure networks.
2.
Prepare the out-of-band (OOB) OpenFlow management network.
The controller communicates with the OpenFlow-enabled switches over a Layer3 (L3) IP network,
known as the OpenFlow management network. This is typically done using an OOB network.
Connect the management port of each OpenFlow-enabled switch to this network and ensure that
the server used to install the software is physically connected to this network.
3.
Prepare the OpenFlow-enabled switches.
The software supports Dell Networking S4810, S4820T, S6000, and MXL switches. The Dell
Networking operating system (OS) version on the switch must be 9.4(0.0) or later. For OpenFlow
requirements, refer to the SDN Deployment Guide on the Dell Networking documentation website.
Installing a Single-Server Controller
You can install the software on a single server; however, this type of deployment does not provide the
resiliency of a dual-server configured for HA. As shown in the following example, a single-server
deployment:
•
requires you to deploy all AFC components on a single VM or server
•
allows you to deploy associated software on additional VMs or servers as needed
6
Introduction
Figure 1. Single-Server Deployment
Installing a Dual-Server (Active/Standby) Controller
Dell Networking recommends a dual-server controller for resiliency. As shown in the following example,
a dual-server deployment:
•
Requires you to deploy all AFC components on a single VM or server
•
Allows you to deploy associated software on additional VMs or servers as needed
•
Provides an Active-Standby configuration using a single VIP address

The following sections describe deploying AFC.
Installing the Dell OpenStack ML2 Mechanism Driver
For more information, refer to the README.md for the ML2 Mechanism Driver at the following link:
https://github.com/accessfabric/dellmech
Configuring BMP on the Switch
BMP detects the software image to determine if an update is required. To enable BMP interoperability
with the software, dynamic host configuration protocol (DHCP) settings and startup trivial file transfer
protocol (TFTP) configuration settings are optimally configured.
NOTE: To enable BMP, the switches and the controller must be in the same L2 network. Also, the
image loading location drive and the primary boot location must be the same.
BMP is enabled or disabled based on current settings. To configure BMP, enable it manually. When you
install the active controller, enter the IP address of the standby controller. For more information about
BMP, refer to the BMP chapter in the platform-specific Dell Networking OS Configuration Guide and the
SDN Deployment Guide.
If the software is upgraded, reinstalled, or the following settings are changed, you must reconfigure the
applicable configuration settings.
•
Management network or IP network for nodes
•
VMs are migrated to a different hypervisor with a different management network
•
New deployment scenario (Single-server to dual-server or dual-server to single-server)
•
Reset of database contents
•
Switch firmware upgrade
•
Configuration values
•
Enabling or disabling features
If you have not manually configured the switches in the fabric, BMP is automatically enabled to update
the firmware and change the necessary configuration values. If you have manually configured the
switches in the fabric, Dell Networking recommends backing up the current configuration before
enabling BMP. To back up the current configuration, use the copy running-config flash://
initial_config command.
After you set up the switches and controller, use the reload-type jump-start command to enable
BMP in Privilege mode on any switches that are NOT already OpenFlow enabled.
After you set up the switches and controller, use the reload-type bmp command to enable BMP in
Configure mode on any switches that are already OpenFlow enabled.

Connect to Legacy Networks
The server fabric edge ports connect to the legacy switches running traditional L2 and L3 protocols.
Regardless of deployment mode, legacy switches cannot use L3 routing in the server fabric. All L2 VLANs
that you configure on the legacy switch must also be configured on the server fabric. The controller is
notified of the VLANs through the north-bound application programming interface (API). Fabric edge
ports that connect to legacy switches are considered uplink ports.
The following lists the requirements for legacy networks to connect to the server fabric:
•
You can open Active Fabric in either End Host mode or as a transient logical switch.
•
In End Host mode, ingress traffic on uplink ports is not forwarded or flooded back to other uplink
ports.
•
End Host mode requires that you connect the legacy switch to the Active Fabric in VLT fashion (you
do not need to enable the VLT protocol in the legacy switch).
•
If you operate the Active Fabric as a single logical switch, ingress traffic on uplink ports can be flooded
or forwarded to other uplink ports.
OpenStack Legacy Configuration
Unlike a legacy router or switch connectivity through the uplink, for an OpenStack configuration, the
northbound traffic enters through OpenStack router running on the server that routes the traffic through
another L3 interface. The routed traffic is sent on an internal VLAN to the legacy router or wide-area
network (WAN) switch using the server fabric.
Using the AFC GUI, identify and configure the uplink port and the WAN port (the port on the switch
connected to the OpenStack router). Configure a policy that defines these two ports as capable of
sending and receiving traffic. The AFC software installs a private VLAN path on these ports to route traffic
to and from the OpenStack router to the legacy switches.
Configure the Uplinks
To configure uplinks, you can use the Fabric Edge utility. When you create the uplink profile, identify the
fabric switch MAC address and the port where the uplink device is connected. You can create policy
templates using the policy dialog box. To apply the created policies to associate with the uplink, the
policy association.
Uplink ports go through an onboarding process. While the fabric is created, all uplink ports are in the
Blocked state to be able to listen and participate in LACP protocol negotiation. In this state, only the LLDP
and LACP packets are sent to the controller and all other packets are dropped.
If you connect the fabric to legacy switches using VLT-like configuration (no VLT protocol required), the
LACP module running on the controller presents itself as a single logical switch and creates a logical port
channel on the legacy switch. After the LACP protocol negotiation completes, the controller moves the
ports to the Learning/Forwarding state. The controller puts the uplink ports in the Forwarding state only if
the uplink profile includes the switch and port IDs.

To set up and configure the fabric, follow these steps.
Step 1 — Weaving the Fabric
1.
Set up the head nodes (for example, two S4810 switches).
2.
Connect the uplinks from all the chassis in the racks controlled by the nodes to the leaf nodes
operating as a VLT-like configuration (no VLT protocol required) pair.
NOTE:
Steps 3 through 5 only apply if you are using MXL blades in an M1000E chassis as leaf nodes in the
fabric.
3.
Connect the load handling system (LHS) ISDN-oriented module interface (IOMs) on the three chassis
in the rack using two base–40GbE links and repeat this process with the resource hosting subsystem
(RHS) IOMs.
4.
Connect the chassis management controller (CMC) management interfaces, head node
management interfaces, and controller interfaces to the management network.
5.
Configure the OOB IP addresses and gateway IP addresses on all the IOMs to be connected to the
fabric.
6.
NOTE: Steps 6 through 8 only apply if you are NOT configuring the switches with a BMP
reload. If you are configuring the switches for a BMP-type reload, ignore steps 6 through 8.
Select one of the following values for cam-acl:
•
0 (default): No space is allocated for OpenFlow. Change this value to four or eight to enable
OpenFlow.
•
4: Allocates space for up to 242 flow entries (14 entries are reserved for internal purposes from
the 256 available flows, leaving 242 entries for use by OpenFlow). For S6000, entering a 4
allocates space for up to 498 flow entries (14 entries are reserved for internal purposes from the
512 available flows, leaving 498 entries for use by OpenFlow).
•
8: Allocates space for up to 498 flow entries (14 entries are reserved for internal purposes from
the 512 available flows, leaving 498 entries for use by OpenFlow). For S6000, entering an 8
allocates space for up to 998 flow entries (14 entries are reserved for internal purposes from the
1012 available flows, leaving 998 entries for use by OpenFlow).
The following sample S4810 configuration reserves 512 entries for OpenFlow:
Dell(conf)#cam-acl l2acl 3 ipv4acl 2 ipv6acl 0 ipv4qos 2 l2qos 2 l2pt 0
ipmacacl 0 vman-qos 0 ecfmacl 0 openflow 8 fcoeacl 0 iscsioptacl 0
7.
Select one of the following values for cam-acl-vlan:
•
0 (default): No space is allocated for OpenFlow. Change this value to 1 to enable OpenFlow.
•
1: Enables OpenFlow functionality.
The following sample configuration shows a value of 1 for cam-acl-vlan:
Dell(conf)#cam-acl-vlan vlanopenflow 1 vlaniscsi 1

NOTE: Reboot the switch after changing the cam-acl and cam-acl-vlan values. If you do
not reboot the switch, the configuration changes do not take effect.
If you enable BMP 3.0, use the reload conditional nvram-cfg-change command. You
must reload the chassis to upgrade any configuration changes when you have changed the
NVRAM content.
Step 2 — Enabling the Fabric
1.
Start the fabric nodes and configure BMP on the IOMs to connect to the network DHCP server.
2.
Download the latest version of Dell Networking OS that supports active fabric (9.4 or later).
3.
NOTE: Steps 3 and 4 do not apply if you are using BMP for installation.
Enable OpenFlow on all interfaces on the fabric node IOMs.
4.
Enable OpenFlow on all fabric node internal links.
Step 3 — Enabling the Controllers
1.
Start the controller and the fabric discovery process.
2.
Assign controllers as active or standby.
3.
Create or update the logical network database of connectivity by connecting the active controller(s)
to all fabric nodes.
Step 4 — Configuring the Provider Networks
1.
Configure the uplink interfaces that connect the switches to the core network.
2.
If there is more than one provider, create multiple provider networks.
Step 5 — Enabling the Tenant Workload Configuration using OpenStack
1.
Enable tenants to specify workloads, including network requirements.
2.
Associate a provider with each workload created by the tenant.
Step 6 — Enabling Server High Availability
1.
30
Configure NIC teaming on server interfaces with appropriate Bond mode to operate in Active-Active
or Active-Standby modes.
