Flexconnect AP stuck in Standalone Mode

[rahul nair]

Hi all ,

I have all of my APs configured under flexconnect at the remote site .

I have one controller at the main office .

There are two redundant MPLS links going from the main office to the remote site .

Now the issue is , whenever my MPLS does a failover to the redundant link , all of my  flexconnect APs disappear from the controller .

I understand that this is due to the heartbeat timer getting expired , and the AP moving into Standalone mode .

But the flexconnect APs take an awfully long time , to shift back to connected mode , after the MPLS failover completes ( which is usually half a minute max ).

Infact it takes such a long time that , i have to manually shut/reset the switch-ports(POE) on which all the APs on the remote site are connected !! 

Is there some tweaking that i am missing here ? or should i be upgrading my firmware ? By the way my controller is currently on S/W ver : 7.4.121.0.

If you have a test controller you can test this with different code of WLC software. Otherwise reach Cisco TAC and see any known issues with this code on this.

Hi Rahul,

Did you try the code upgrade. Did it resolve the issue ?
