How to change netmask on management interface for wireless lan controller

[a17ha9001]

Hi

I will like to know how to change the management interface on a WLC, the Netmask is currently a /23 but will like to change to a /22.

I noticed that the configuration by default is grayed out when I check the GUI, can I have assistance on best practice how to change the ip address and Netmask and also the risk involved?

Many thanks in advance.

Hi

you can change the mgmt. int under the cli , just make sure all your other devices using that subnet range are changed as well to match , if that's what your now going to be routing instead of /23
