Changing the IP address in CUCM 7.02

Follow the steps below to change the IP address of the Cisco Unified Call Manager Publisher server.


Environment Overview


CUCM version 7.02 running as a virtual machine on VMware Server 2.0. The virtual machine was moved to a different VMware server and subnet.



1) On the new VMware host server in VMware Infrastructure Web Access, go to the settings for the CUCM guest and change the network adapter connection to vmnet1 (hostonly)



2) On the VMware host server change the IP address and subnet of the vmnet1 network adapter to an IP address in the same subnet as the existing IP address of the CUCM. You don't need to set a default gateway on the network adapter.



3) Log into the CUCM via the CLI (I used the VMware Console to access the CLI) and change the default gateway to the new default gateway you want to use using the following command:

set network gateway gateway_ipaddress

4) Log on to Cisco Unified CM Administration and under System > Server > your CUCM server, change the IP address to your new IP address and click save.

5) Back on the CLI change the IP address using the following command

set network ip eth0 ipaddress subnetmask

The CUCM should now reboot.




6) Back on the the VMware host server in WMware Infrastructure Web Access, go to the settings for the CUCM guest and change the network connection back to vmnet0 (bridged).




7) Once the CUCM has rebooted you should now be able to access it via the new IP address. You can check the IP address has change via the CLI using the following command:


show tech network hosts
