I have an issue with telnet connection on switches in a cisco nac en vironment. I have deployed nac in inband virtual gateway mode:
I have a 3560 switch (configured as L2) aggregating several trunks from other L2 switches This switch is trunked to the nac server and the nac server is trunked to a layer 3 switch in which there is intervlan routing and svi from all vlans.
The issue is that i can not telnet to the L2 switches in the intrusted side of the network when i am in one of the untrusted side vlans. It says connection refused.I tried to clear the lines configured the vty lines for telnet access and required login but still telnets to the switches in the untrusted side does not work. A telnet from the untrusted side to the trusted side works fine. I authorized telnet traffic port 23 in both directions but it does not work please help
