You want 802.1Q tunnelling, frequently referred to as Q-in-Q. Basically: int gig 9/9 switchport switchport access vlan 9 switchport mode dot1q-tunnel As a "TLS" product offering there are related commands for STP, CDP, VTP treatment but for your application the above should see you through. http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/dot1qtnl.html Cheers Ross _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
