Cisco 3560X AAA Authorization Failed

[johnlloyd_13]

hi all,

we have a 3560X and can't seem to login remotely. having logs below.

Switch Ports Model              SW Version            SW Image                 
------ ----- -----              ----------            ----------               
*    1 54    WS-C3560X-48P      15.0(2)SE2            C3560E-UNIVERSALK9-M  

May 11 01:54:16.264 UTC: %AAA-3-ACCT_LOW_MEM_UID_FAIL: AAA unable to create UID for incoming calls due to insufficient processor memory
 

connecting via console and using TACACS+ account is working file.

the same config was applied on other switch and remote access to other switches are fine.

tried to re-apply AAA but still the same.

seem to be having the same issue from this blog.

was thinking to have an outage window to reboot switch and if that didn't help i might need to upgrade the IOS.

did anyone had the same issue and what's the fix?

This symptoms sounds very much like there is a memory leak which results in depleting available memory to the point where it can not process the AAA request. In the short term a maintenance window to reboot may buy you some (temporary) relief. But the long term solution is probably a change in the version of code.

hi rick,

same sentiments here.

might as well perform an IOS upgrade.
