Hi, I have an a switch C2924-XL with software installed 12(05)WC8.

I have configured port fastethernet 0/22

on trunk mode 802.1q and I need to cross

traffic here only at six Vlan (10,11,12,13,14 and 15) but not to Vlan 1.

I have tryed to do native Vlan on this

port from Vlan 1 to Vlan 10 but when I enter "switchport trunk allowed Vlan 10,11 etc" after I see ever Vlan 1 appear also.

How can I block Vlan 1 from this port ?

best regards

Lorenzo
