Cisco Cisco 2106 Wireless LAN Controller

CSCso45207–In some cases, a 1522 or 1524 mesh access point would get in a lockup state at startup 
after a soft reset. All interfaces were down and the console interface was non-functional. An AVR 2 
interface error was often seen at startup; however, no further symptoms were seen once the MAP 
was up and running. This lockup state only occurred at startup, following a soft reset. The 
workaround was to power-cycle the access point.

The following caveats represent those bugs that are closed and not actively being investigated but might 
still represent active conditions in a product. Workarounds are provided.

CSCsl15941–On the 1520, when operating in the -K regulatory domain, channels on which radar is 
detected might allow a MAP to join the disallowed channels if the antenna gain on a RAP is:

changed from a starting value between 0 and 16 to a value greater than 16.

changed from a starting value that is greater than 16 to a value less than 16.

Workaround: None.
