authentication issue with c2960x-universalk9-mz.152-7.E4.bin ?

[steeveb12]

I updated my 2960x to the latest OS "c2960x-universalk9-mz.152-7.E4.bin" and now I cannot authenticate through radius, I have to login with the local credentials. Any idea why?

c2960x-universalk9-mz.152-7.E4.bin  - as i remember there was a bug on this version, don't have in hand to give information.

also, post radius config. (from what version you upgraded ?)

if you upgraded from OLD version also check the new syntax :

I was running of c2960x-universalk9-mz.152-7.E2.bin and unless I overlooked at the syntax version E4 said it should of been the fix for Tacas syntax.

The commands have changed with new IOS 

You can check the release notes.

base on the release note the issue was with c2960x-universalk9-mz.152-7.E3.bin and it should of been fixed with E4 version... Unless I overlook some stuff.

so I had to change my syntax to this 

tacacs-server host IP xxxxxx Key xxxxxxx
tacacs-server host IP xxxxxxx Key xxxxxx
tacacs-server directed-request
tacacs-server key xxxxxxx
tacacs server xxxxxxx
key xxxxxxx
tacacs server xxxxxxx
key xxxxxxxxxxxx
