I have 3 controllers. 2 of which are in the same subnet, there are wlan's anchored to the third is controller, which is in the DMZ. Issues are as follows:
1. Cont No one: Shows Control and Data Path Up, between it and the controller in the DMZ, can eping and mping
2. Cont No Two: Shows Data Path down, between it and the controller in the DMZ, can not eping but can mping
3. Firewall Rules remain the same as before the issue occurred.

>>> Firewall Rules remain the same as before the issue occurred <<<
did this issue suddenly occur ? or is it only recently noticed?
Are the controllers in HA configuration or N+1 redundancy?
if HA, then a failover (with no fallback) may have taken place?
I assume you've all ready checked all controllers are added to the mobility group on all devices!

Hi
All controllers are added to the mobility groups.
Controllers are in HA, there was a failover and it did not fallback, I forced the switchover, I have rebooted both the local controller and the controller in the DMZ.
This may be a coincidence, but this happened soon after we had lost our vlan dtatbase on our core switches.

Hi Scott
The core is all back to normal, I have failed the controllers back, everything is working correctly, apart from one Mobility Group between 2 controllers.
thanks

This turned out to be a Firewall Issue, now resolved.
