NAC issue with DHCP

Unanswered Question
Nov 26th, 2008

There are a few computers in the building that when they start i have to do a repair in the connection. If i put those same computers in the admin Vlan(doesn't goes through NAC) i dont need to do the repair. I think something is blocking in the unauthenticated role. But the rare thing is that i'm allowing the DHCP and Active directory servers on the unauthenticated role.

I have this problem too.

The "Enable VLAN Pruning" option is enabled by default for CAS Virtual Gateways. Make sure that "Enable VLAN Pruning" is turned off when "VLAN Mapping" is disabled. Turning the "Enable VLAN Pruning" option on when the "VLAN Mapping" option is disabled can cause the CAS to discard all VLAN packets from passing through in either direction.
