ACS 5.4 shared key issue

[Nursultan Bolatbayev]

Hello, guys.

I have ACS 5.4 and 2960 switch.

I have configured aaa with tacacs.

But every time I get error:

13017 Received TACACS+ packet from unknown Network Device or AAA Client

But I several times checked shared key on both sides and changed it, but no success.

There are my configs

aaa group server tacacs+ acs
 server 192.168.124.140
 ip tacacs source-interface Vlan2
aaa authentication login default group acs local
aaa authentication enable default group acs enable
aaa authorization exec default group acs if-authenticated 
aaa accounting update newinfo
aaa accounting exec default start-stop group acs
aaa accounting commands 0 default start-stop group acs
aaa accounting commands 1 default start-stop group acs
aaa accounting commands 15 default start-stop group acs

tacacs-server host 192.168.124.140
tacacs-server key hehe

Is your VLAN 2 interface the one with the IP address from the ACS.jpg screenshot?

Thank you for rating helpful posts!

Hello. 

Yes it is. If it wasnt, it would be another error

Sorry, actually this error

13011 Invalid TACACS+ request packet - possibly mismatched Shared Secrets that one was with another device, though everything is configured correct too, I think
