Solution

This can be done thru clish. Please make note of the current IP address and logical interface name. For this example, we are changing the IP on eth1c0 from 192.168.1.2 to 192.168.2.5 on a 24 bit subnet mask. We first need to delete 192.168.1.2: Nokia> delete interface eth1c0 address 192.168.1.2 Now we can add the new IP to eth1c0: Nokia> add interface eth1c0 address 192.168.2.5/24 If the interface is part of a vlan, then you will need to include it in the command. If the above IP was on vlan2, the command would be: Nokia> add interface eth1c0 vlanid 2 address 192.168.2.5/24 You can verify the configuration also: Nokia> show interfaces ... Physical Interface eth1 up Logical Interface eth1c0 Active on link_avail up Type Ethernet IP Address Destination 192.168.2.5 192.168.2.0/24 ... Remember to save your configuration: Nokia> save config Note: This will only change the IP address in Nokia IPSO. If you have to change the IP configuration in an application, you will have to go into the configuration for that application and ensure the configured IP address is correct.
