RF Group members not seeing each other

[theophile]

Hello, I've two wlc model CT5508 version 7.0.116.0. They are working fine except for the RF grouping part. When I look at the RF Group members part in the configuration, I can see only one wlc (the one I'm connected to). If I connect to the second one, in the same part, I've just one controller (so the second one..). I tried to restart the algorithm but no change. Each controller is configured with Group Mode set to auto, and their respective role are auto-leader...

I tried to change the  RF group name on both wlcs, but it didn't fix the problem. When I look at the logs, there is one which appear quite often:

*emWeb: Nov 29 10:32:07.764: %LOG-6-Q_IND: dtl_arp.c:2581  ARP input q exceeds limit. Current val = 50 [...It occurred 38 times.!]

I don't know if it's linked to my problem but if you have an idea, any help really appreciated!

Thanks

Théophile

The only time I see that is if there are no AP's on the other WLC.  Once I put AP's on both, then the RF Group starts to populate.  If you do have AP's joined on both WLC's and your RF GRoup name is the same, I don't know the answer to that. except maybe change the RF Group name on both and see if that fixes it.

Thanks Scott, you were right, there were no AP on the second wlc.

Cheers
