Changing Switch IP configured on AP

Changing IP address of the Aruba controller caused all APs to be disconnected.  All APs are connected directly to the Aruba Controler, and "show int" command shows that all APs are still connected, but none of the APs are accessible/visiable in WebUI.

 

Per "show ap database", APs are still referring to an old IP address of the Aruba controller.  

 

Any ideas/suggestions on how to make APs visible to Aruba Controller?

 

Thank you,

Re: Changing Switch IP configured on AP

Hi, 

 

How many APs are deployed ?

How the AP is identifying the master ? (static, dhcp, DNS)?

please share "show datapath sess table <ip of AP> " output and show ip interface brief ouput. 

also let me  know the old IP.

Re: Changing Switch IP configured on AP

I see that APs are trying to communicate to a different Ip (10.51.0.110) ?

 

can  you tell what that  IP is ?

 

172.25.2.37 10.51.0.110 17 8211 8211 0/0 0 0 1 1/8 25 FC

172.25.2.47 10.51.0.110 17 8211 8211 0/0 0 0 1 1/2 6a FC
172.25.2.42 10.51.0.110 17 8211 8211 0/0 0 0 0 1/14 f FC
172.25.2.11 10.51.0.110 17 8211 8211 0/0 0 0 0 1/18 20 FC

Re: Changing Switch IP configured on AP

It seems that there was a problem with our RADIUS server - it was blocking request coming from APs

 

Thank you for the help
