Can't access controller GUI while in HA on primary controller

Unanswered Question

I have setup HA between two 5508 controllers.  The status from the CLI shows they are connected and active in HA primary and secondary mode on the appropriate controllers.

Once I have enabled HA SSO I am unable to connect to the primary controllers GUI from either the service port or the management port.  I know that I will not be able to access the standby unit's GUI while in standby mode.

I have tried the management IP and the Redundancy Management IP and I am unable to get the GUI to come up.  If I disable HA mode then I can get into the GUI via the management IP and the service port.

I am running version 7.4.110.

Any suggestions?

Hi Seth,

you were able to solve this out? We're facing the exact same symptoms that you described.

Thank you!

I did.  I was accessing the controllers remotely thru another PC that was on the network with the controllers and it had to do with the way I was accessing them.  When I connected localy it worked just fine.

I see, you understood how the HA was related to that? What was different when you were accessing to the equipment in standalone mode and HA that could cause the GUI to be unavailable?

To be honest with you it is hard for me to remember exactly what worked and did not at this time.  The HA and STANDBY unit were on one subnet and the remote PC was on another and I had to force to route to the units.  When I was at the lab and directly place my laptop on the same subnet as the units it worked fine.

The difference was the machine I was using to access the units when I was remote.  I had to remote into the PC and then from that PC access the units.  Once I eliminated that other PC it seemed to work fine.
