Changing IP Address Controllers

Hi, 

 

Own two 5508 controllers operating in HA SSO. Became necessary to accomplish the change of addressing these. Both addresses will remain the same subnet, however the question arose whether to undo the HA configurations or is there a way to alter these addresses without removing these settings. 

Thank you.

You'll need to break HA,

You'll need to break HA, change the IP address of the Management and the Redundant Management (as necessary).

Leo is correct... Disable AP

Leo is correct... Disable AP SSO and reconfigure the management IP address for both. You can change the AP's high availability for the primary WLC with the new IP address also before your break AP SSO and change the IP address. This way the AP has the info.

If The new IP is going to

If 

The new IP is going to remain in same subnet

Gateway is going to remain same

Redundant peer IP is going to remain same.

then on the active controller you can go ahead and change the IP, and it will be overwritten on the standby, you might not have to break redundancy.

your AP's however need to re-register, option 43 and DNS entry have to be changed.

Let me know if it worked for you

Hi Ammahend,Thanks for your

Hi Ammahend,

Thanks for your reply. 

The Subnet will change, for example, will 10.10.xx/24 network to network 10.20.xx/24. 
I believe if you change the subnet, you must disable the HA controllers. Correct or not you need to disable. 

Thanks for all the support. 

Igor
