Access Points Rebooting - VRID Problem

I have a really weird issue that occurred tonight while performing an upgrade. I was in the process of decommisioning a pair of Citrix Netscaler 7000's in HA and replacing them with a new pair of 8200's in HA. The 8200's were configured with the same settings as the 7000's except it was running a newer version of code.

 

As soon as I turned off the old netscalers and turned the new ones on, I started getting Airwave alerts that AP's were rebooting. I checked that all the controllers were up and DNS was working for "aruba-master". I didn't have time to troubleshoot, so I reverted back to the old netscalers and the Aruba issue resolved itself. Now that I have some time, I started looking in the logs and see the following:

 

Aug 28 18:43:24 :208056:  <ERRS> |fpapps|  Invalid version received for VRID 48
Aug 28 18:44:25 :208056:  <ERRS> |fpapps|  Invalid version received for VRID 48
Aug 28 18:45:26 :208056:  <ERRS> |fpapps|  Invalid version received for VRID 48
Aug 28 18:46:27 :208056:  <ERRS> |fpapps|  Invalid version received for VRID 48
Aug 28 18:47:28 :208056:  <ERRS> |fpapps|  Invalid version received for VRID 48
Aug 28 18:48:29 :208056:  <ERRS> |fpapps|  Invalid version received for VRID 48
Aug 28 18:49:30 :208056:  <ERRS> |fpapps|  Invalid version received for VRID 48

 

We have 3 Aruba controllers in a Master local setup. We have one master controller that serves as a backup for the two local controllers. We have 1 VRRP setup on each of the two local controllers. It almost seems that the Netscalers were somehow messing up the VRRP setup on the Aruba's. When I do a "show vrid -summary" on the Netscalers, it shows two virtual routers with ID's 48 and 49 (which are the VRRP's used by the Aruba's). Can someone confirm or elaborate what is going on here? I'll admit I'm not an expert on VRRP. Thanks.

Re: Access Points Rebooting - VRID Problem

I think you figured out the conflict.  The best thing would be to setup an authentication key between the VRRP instance (2) so that it would not conflict with the netscaler.
