Description (partial)


When a 2106 WLC running a 4.2 version of code is having APs joining it and downloading the 4.2 AP code, if the WLC is attempting to download a 6.0 code, the WLC runs out of memory and leads to printing of a lot of messages and eventually crash.


A WLC which is running a 4.2 code and which has APs joining/downloading the 4.2 AP code may at times have low flash memory. This may result to not sufficient space for a new WLC code like 6.0 to be downloaded.  Hence if attempted to download the new WLC code, there arises a possibility wherein the WLC may run out of memory and crash.
