Introduction
This configuration guide provides advice on provisioning new HPE Comware switches in your network automatically, fresh out of the box, without setting up console access into the switch or typing commands manually to configure credentials and enable remote network management access.
Two environments are described in this guide:
•
With HPE Intelligent Management Center (IMC)
•
Without HPE IMC
Note:
HPE FlexFabric 5900 and 5930M switches worked as expected using the steps described in this guide. Other HPE Comware switches should also function in the same manner.
Environment 1: With HPE IMC
The example configuration described in this section is applicable in environments with HPE IMC already deployed and assumes the new switches will also be deployed in the same IP subnet as the DHCP server. Refer to the last section of this guide for additional configuration guidance if the new devices are in a different IP subnet.
Requirements
The following are required:
•
DHCP server (Windows® server 2012 is used in this example)
•
HPE IMC (7.1 base platform was tested during creation of this document)
•
MAC addresses of the new switches (using sticker pasted on the switch) would need to be recorded.
Network topology
The topology as shown in figure 1 will be used to describe environment 1:
•
The new HPE Comware v7 Switches will connect into the existing Out-of-Band (OOB) management network using their management
Ethernet port
•
L2 network connectivity exists between the new switches and DHCP server/HPE IMC
•
HPE IMC and DHCP server exist on the same subnet

Step 1.1: HPE IMC configuration
Navigate to the HPE IMC > Service > Configuration Center > Auto Deployment Plan and click on the Initial Configuration File Management link as shown in figure 2.
Figure 2. ADP configuration (Part 1)
Click on “Add” to create a new initial configuration file as shown in figure 3.
Figure 3. ADP configuration (Part 2)
Create the new Initial Configuration file using the following parameters and click OK to add as shown in figure 4.
File Name: oobm.cfg
Description: OOBM autoconfig startup configuration file
File Content: sysname ADP_Initial_Config
# interface M-GigabitEthernet0/0/0 ip address dhcp-alloc

# return
Note:
The snmpv1 read and write community strings, as well as the telnet username and password must match exactly what is shown in the access parameters in figure 4.
For e.g. if IMC shows iMCV5read, iMCV5read has to be used. If IMC shows iMCread, iMCread has to be used.
These parameters will be used only for the initial discovery and will be overwritten during the deployment of the devices’ desired configuration.

Step 1.2: Windows 2012R2 DHCP server configuration
As shown in figure 6, configure your DHCP server with its desired network scope, then add two more options. Option 66 will specify the TFTP server IP (HPE IMC), while option 67 will specify the initial configuration file the new switches should boot up to, as previously created in step 1.1.
Figure 6. Windows DHCP server configuration
Step 1.3: HPE IMC configuration
On the HPE IMC server, navigate to Service > Configuration Center > Auto Deployment Plan and click Add to create a new auto-deployment plan with the following parameters as shown in figure 7.
Figure 7. ADP configuration (Part 5)
Configuration guide
Configure using these values as shown in figure 8, “Name: OOBM”
Page 7
Figure 8. ADP configuration (Part 6)
Create the desired configuration file for the final deployment by using Service > Configuration Templates > Add > Manual Add as shown in figure
9. This configuration file may include normal configuration template variables as typically defined in an HPE IMC configuration template (please see IMC administrator’s guide for more information).
Figure 9. ADP configuration (Part 7)

The following sample configuration template is used (modify as required for your own environment). In this example, we are defining fixed values for static route/telnet/snmp, but sysname and OOBM IP address can be changed for each individual device.
Sample configuration template: telnet server enable sysname ${DEVICE-SYSNAME}
snmp-agent
snmp-agent community write private
snmp-agent community read public
snmp-agent sys-info version all local-user admin class manage
password simple password

authorization-attribute user-role network-admin user-interface vty 0 15
authentication-mode scheme fan prefer-direction slot 1 port-to-power interface M-GigabitEthernet0/0/0
ip address ${MGMT-IP-ADDR} 255.255.255.0 ip route 15.0.0.0 255.0.0.0 10.10.10.254
From the OOBM deployment plan, select the Add Auto Deployment Device icon
as shown in figure 10 below.
Figure 10. ADP configuration (Part 8)
Configuration guide
In this example, we will set the following values:
MGMT-IP-ADDR: 10.10.10.75 #this is the IP address to be assigned to the OOBM port.
DEVICE-SYSNAME: DC1-5930-1 #this is the device sysname to be assigned
Ensure that the
Back Up Configuration File option is set to No as shown in figure 11.
Note:
Also ensure device IP specified is not already managed by IMC for any other device.
Page 9
Figure 11. ADP configuration (Part 9)
As shown in figure 12, input the Match Criteria: MAC Address field with the MAC address of the target device. This is the MAC address stated on the sticker pasted on the device.
Input the Target IP address of the device. This is the final IP address that you wish to use for managing the device.
Configuration guide
Page 10
Figure 12. ADP configuration (Part 10)
As shown in figure 13, specify the access parameters here to match those of the final state of the device (e.g. SNMP and telnet settings below have to match 5930.cfg selected above). These settings will be used by HPE IMC to contact and discover the device during the final stages of the auto-deployment. If these settings do not match, the auto-deployment task will fail.

Environment 2: without HPE IMC
The example configuration described in this section is applicable for environments without HPE IMC and assumes the new switches will also be deployed in the same IP subnet as the DHCP server. Refer the last section of this guide for additional configuration guidance if the new devices are in a different IP subnet.
Requirements
The following are required:
•
DHCP server (Windows Server® 2012 is used in this example)
•
TFTP server (3CDaemon application is used in this example and installed on the same Windows Server VM)
There is no requirement to identify MAC addresses of the new switches for this to function as expected.
Network topology
The topology as shown in figure 15 will be used to describe environment 2:
•
The new HPE Comware switches will connect into the existing OOB management network using their management Ethernet port
•
L2 network connectivity exists between the new switches and TFTP/DHCP server
•
TFTP and DHCP server exist on the same subnet

Step 2.1: TFTP server configuration
A .cfg file will need to be created in the TFTP server directory; this directory will depend on your TFTP server application. Launch “Notepad”,
“Save As” select the correct directory, rename the file as desired, and save. The file name is not fixed. In this example, it is saved as 5900.cfg as shown in figure 16.
Figure 16. cfg file creation
Fill in the .cfg file with your desired switch configuration. Here is the sample configuration used; additional configuration may be added or changed as desired. interface M-GigabitEthernet0/0/0
ip address dhcp-alloc
# telnet server enable ssh server enable
#

Here is an example for other additional configurations such as VLANs, OSPF etc., which maybe added into the above .cfg file. vlan 10 to 11 ospf 1
area 0.0.0.0
network 192.168.11.0 0.0.0.255
Step 2.2: DHCP server configuration
As shown in figure 17, configure your DHCP server with its desired network scope, then add two more options. Option 66 will specify the TFTP server IP (same IP as the DHCP server), while option 67 will specify the configuration file the new switches should boot up to, as previously created in step 2.1.
Figure 17. DHCP Server option settings
Step 2.3: Connect and power up new switches into the OOB network
With the previous steps done, connect (only the management Ethernet port) and power up the new switches into the OOB network. The following console output as shown in figure 18 should be seen with initial zero touch provisioning complete. The IP address assigned to the switch will be shown; the TFTP server console should state the .cfg file was sent as expected.
If console access is not available, the IP addresses assigned in the DHCP server address leases as previously shown in figure 5 can also be used to identify the IPs and establish remote network management access.
Configuration guide
Page 16
Once initial zero touch provisioning is complete and working as expected, the network administrator can proceed to cable up the remaining ports into the DC fabric and configure device specifics such as unique “sysname”, static management IP, uplink IPs etc. As IMC is not available to complete the rest of the desired configuration, CLI via remote network management access will have to be used in this environment.
Note:
This procedure should not disrupt existing switches with saved configuration if they reboot. The existing switches will not initiate the automatic configuration attempt shown below.
Figure 18. New switch boot up

For devices without L2 network connectivity to the DHCP server
This section is applicable for environments where the new switches need to be deployed in a different subnet from the DHCP server. The procedures from environment 1 and 2 are still applicable; the only additional configuration required is DHCP relay on the default gateway switch.
Network topology
The topology as shown in figure 19 will be used to describe this environment:
•
The new HPE Comware switches will connect into the existing network using their management Ethernet port
•
L3 network connectivity exists between the new switches and TFTP/DHCP server
