AP failover not working properly on HA-lite redundancy setup

[ Edited ]

Hello,

 

we have two 7240 controllers on dual mode with HA-lite setup, running 6.4.2.3.

when the APs miss a few heartbeats (~10sec) they try to failover, but when the connection is restored the APs fall into a state, where they are assossiated with their original master but user sessions are tunneled to the controller who was their Standby and clients are stuck in logon status.

 

We have removed Backup LMS configuration and also tried with and without controller state-sync with no success.

 

Aruba TAC has been contacted, but haven't given any solution yet, so I 'm wandering if anyone had a similar problem and if he can propose something we could try.

 

I can see some errors in:

 

#show ap remote debug mgmt-frames ap-name "test-AP
Timestamp stype SA DA BSS signal Misc
--------- ----- -- -- --- ------ ----

also

 

#show ap remote debug sta-msg-stats ap-name "test-ap"

Message Stats

while 

#show datapath tunnel table 
shows the IP of the correct/active controller

The backup LMS is unnecessary in an HA configuration.

 

How many controllers do you have?

Which of those controllers are part of the failover group?

What role is each controller set to? Active/dual/standby.

Do you have IP Mobility configured?

The backup LMS IP should point to the standby controller.

Re: AP failover not working properly on HA-lite redundancy setup

we are focusing the problem between two controllers in dual mode.

Both part of the failover group.

IP Mobility is not enabled.

 

Backup LMS was initially configured, but we removed it based on a bug related to HA-Lite on latest release notes (and TAC's suggestion). Problem persists either way.

 

Apart from countless reports of users in a couple occations when a building link went down for a few seconds, we have tested with a test ap-group with a unique AP and seperate SSID, to avoid roaming connections of the client. 

Disconnecting the upling of the switch where we have connected the test-ap triggers the event.

Re: AP failover not working properly on HA-lite redundancy setup

This appears to be bug#105294 which is marked fixed in AOS 6.4.2.4

Unfortunately bug discription on the release notes is not very close to how we were experiencing this problem.
