After an upgrade to any 12.3-based image, a non-root bridge cannot re-associate to the root bridge when it reboots


Core Issue

This problem occurs for bridge links which are more than one kilometer and have the distance command configured, as shown:

bridge(config-if)# distance 10

These are the affected bridge and Access Point (AP) platforms:

  • BR 1310 and BR1410 running 12.3(2)JAx, 12.3(7)JAx (x<_3 _="_" _12.38ja="_12.38ja" and="and" imagesbr="imagesbr">
  • AP 1200 series, AP 1230 AG series and AP 1240 AG series running the 12.3(7)JAx (x<_3 _="_" _12.38ja="_12.38ja" and="and" imagesbr="imagesbr">


This problem is documented in Cisco bug ID CSCsc60665.

As a workaround, toggle the station role of the non-root bridge radio to root and then back to non-root . This may restore connectivity. This is an example:

bridge(config-if)#station-role root bridge
bridge(config-if)#station-role non-root bridge

If the bridge stays powered up, the connection is stable (-64 and -62 ).

This problem is fixed in 12.3(7)JA3 and 12.3(8)JA1images.
