Change controller IP address?

How difficult would it be to change the IP address of the aruba controller? We have all campus APs and they are set to use Ap discovery to find controller. I really don't want to do this but I might have too.

Re: Change controller IP address?

Hi,

 

It is very simple to change the controller IP ( controller-ip vlan <vlan id> ) but the following will get effected,

 

1. You should reboot the controller to take effect the new IP ( All APs terminating on the same controller will reboot)

2. Master-local will be effected, need to reconfigure

3. Master-standby will be effected, need to reconfigure

4. If the master discovery is DHCP option 43 or DNS need to reconfigure with the new IP ( if the discovery is ADP will not effect)

 

In your case I'm assuming that you have only one controller and you are using ADP ( Aruba discovery protocol) to discovery the master controller, if so you have to change the controller IP and reboot, any way APs will reboot and discover the controller with the new IP by using ADP.

 

Hope got some more clarity,

 

Please feel free for any further query on this.

Cheers,
Venu Puduchery,

Yes we are master-local with HA. So I'll have to reconfigure that if I change IP address. Thanks
