AAA on C9500

[baileyTh]

I have AAA up and running on several switches ( all cisco) but my C9500 errors out with (No authoritative response from any server).  My config for AAA on the C9500 mirrors all the other switches.  All the switches pass thru the C9500 and the AAA server is attached to  the C9500.  I can't send my config but what direction might I look to figure this out?

Can you post what code running on Cat 9500, also AAA config.

(No authoritative response from any server)

This is most probably config, issue, some time Cat 9500 use Manangement VRF, if you using source IP or interface in the config.

Hello,

can you ping the TACACS or RADIUS server from the 9500 ?
