It depends on the platform and IOS version. If it works, you'll be able to just use a 'switchport trunk allowed vlan 2,5,6-8' or similar. If that command fails, it will tell you to include VLAN 1 and 1002-1005. For example, this is on an a 2950-24 running 12.1(9)EA1. A more modern IOS would work as intended (only trunking VLAN 2, 3, 4, 5): switch-1(config)#int f0/1 switch-1(config-if)#switchport trunk allowed vlan 2-5 Command rejected: Bad VLAN allowed list. VLANs 1,1002-1005 are required. switch-1(config-if)# Rgds, - I. -- Ian Henderson, CCIE #14721 Senior Network Engineer, iiNet Limited _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
