Hi,

Please review my TACACS, it's working successfully with vrf.

1) Please advise that groups are created are correct or these can be better configured.

2) I am getting message after 2 minutes of success aaa authentication "Line timeout expired". and the  switch disconnect, while I am configuring the switch. I have used the line vty 'exec 20 0' but that doesn't make any difference. I am using ACS V5.

Thanks.
