I'm trying to add tacacs info to a switch. However, I'm unable to use the new tacacs commands, even though the switch tells me to.

WS-C2960-24PC-L - Version 15.0(2)SE5

switch(config)#tacacs-server host
Warning: The cli will be deprecated soon
'tacacs-server host'
Please move to 'tacacs server <name>' CLI

Ok, so I'll use it that way...

wtc2b1asw01(config)#tacacs server ABC
% Invalid input detected at '^' marker.

Guess I can't.

Any ideas on what I'm missing?

sw-R2-3#show ver | i Software
Cisco IOS Software, C2960S Software (C2960S-UNIVERSALK9-M), Version 15.0(2)SE3, RELEASE SOFTWARE (fc1)
sw-R2-3#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
tacacs  tacacs-server  

sw-R2-3(config)#tacacs ?
  server  Server configuration

sw-R2-3(config)#tacacs server ?
  WORD  Name for the tacacs server configuration

sw-R2-3(config)#tacacs server foo 

aaa new-model maybe?

[back story]
This is one of many of my Cisco peavs... When I was first starting out with IOS (back when IOS 10 was new), I sat down with the ~1000 page documentation on authentication configuration. After a day of "why the f*** doesn't any of this work", I got to page 958-ish, where, as a complete after thought, the authors finally mention, "and you have to enter aaa new-model to turn any of this on." I think I actually burned that handbook. (and was never allowed to go to NANOG, because I might "do something" to that author.) F'ing CCIEs!

  • wow, I knew it was something simple. Thanks for pointing that out.
