Cisco Nexus TACACS username anomaly

[vijayaram]

Hi,

I observed that the Cisco Nexus is not accepting TACACS authentication with usernames completely in numerics. Have any of you faced similar problem? Most of our tacacs usernames are our employee id (not AD) and unable to login. I've followed the procedure exactly in the link below. Currently we are administering the switch with generic tacacs user-ids which have only alphabets. I wanted to know if there are any additional custom attributes specific for Nexus to accept numeric characters in the username.

What Nexus platform and NXOS version are you running?

Please take a look at bug ID CSCta00308.

Hi,

Thanks for the reply.

I was able to get to the correct page where it states that all numerical usernames are not allowed.

We are running 4.1(3)N1(1). I have checked the online documentation, even the latest 5.0(2) release doesn't support all numeric usernames.
