We have recently bought a batch of Cisco 2960x-48LPS-L switches. They where all shipped with c2960x-universalk9-mz.150-2.EX2. We have migrated our standard switch configuration which works fine on Cisco 2960, 3750 switches onto these x series switches but have an issue with TACACS+. When we connect using SSH we get a message regarding Authorisation Failure and are unable to logon. This is exactly the same config as used on other switches. I have seen discussions about old versions of code having issues with TACACS have these been fixed in this version? I have tried upgrading one stack to EX4 but with no difference in outcome.
Got another 20 of these switch planned for the next couple of weeks and TACACS+ is a must so any help would be very appreciated.
Maybe try and zeroize the the ssh keys and recreate them. Also I have seen in the past where cutting and pasting a config the tacacs server keys do not get input correctly. Delete the tacacs server key line and "manually type the whole line with the key .
