Try configuring the port as trunk port . Check if the "controller" options field is not left empty if so configure it to use option 43.

Have you tuned your heartbeat timers? Perhaps the logging output of the AP helps. Try telnetting or ssh'ing the AP directly and view the log of the AP. Alternatively, connect a client in the same VLAN as the AP. The AP broadcasts syslog messages per default.

Hi Johannes,


Can you give me more information on how to tune the heartbeat timers? Is it done on th AP or WISM or both?


Please point me to some good documentation.

Is it something like on the AP:


show advanced timers

config advanced timers ap-heartBeat-timeout x (make that 60 if it was 30 before)

show advanced timers


How do I change it on WISM?

You don't need to change anything on the AP directly. I was asking about the heartbeat timeout, because if you tweak it to much, the problem you described could occur.


Here's a hint:

Search for "New Controller Features" and "High availability"

What is the RCV version of your 1242? What is the LWAP version of the 1242?
