After code upgrade to 7.6.120 , two of our WLC's are crashing. Looks like CSCuo86819 is the cause for one of them.


I do not know for sure on second WLC.

Hesitant to go with beta even though it has a fix for CSCuo86819 because this bug was caused during one of the MR release!

When will this code be tested and be available to public?

Cisco Employee



Thanks for your feedback.

CSCuo86819 is already fixed in 7.6MR3, and included in the beta

The release will be in CCO in the coming weeks.



Community Member

Can you tell me when this version might be released to CCO?

Cisco Employee


The CCO version for 7.6mr3 would be and expected to be released by end of this Month.



Community Member

I noticed that 8.0 code has been released.  Is this the same as 7.6 MR3, or is this a different release?


Hall of Fame Super Silver

That is a different code.  v7.6 MR3 should be out by the end of the month or first week of September.


Cisco Employee



no, 7.6MR3 is a maintenance release, just bug fixes,  8.0 is a new feature release, separated branches/release schedule will be posted soon
