I am just banging my head on the wall and I can seem to figure it out. I am trying to configure my 3750G stack to authenticate to my ACS 4.2 server. The configuration is fine and when I look at the debugs I am getting from the switch that it selected the default profile and that is the extent of the log. On the server I am getting a failed authentication of invalid secret key. I have a multiple times changed the secret key to match and still getting the same issue. I thought that it was because the source interface being a L3 port-channel and changed it to a vlan interface with the same issue.
aaa authentication login default group tacacs+ local
aaa authentication login noauth local
aaa authorization exec default group tacacs+ local
aaa authorization exec noauth local
aaa authorization console
ip tacacs source interface port-channel 1
tacacs-server timeout 5
tacacs-server host 10.224.1.181
tacacs-server key itsasecret
tacacs-server directed-request **must be a default command**
line con 0
login authentication noauth
line vty 0 15
login authentication default
Any help would be appreciated as I don't know if I am hitting a bug or not and searches have turned up nothing.
