I am working a lab that asks you to configure your 3550 port FE 0/12 as
a trunk w/ISL & allow only vlan1 & vlan BB2 across here is what I have
so far -

interface FastEthernet0/12
description BB_2
switchport trunk encapsulation isl
switchport mode trunk
switchport protected
duplex full
speed 100
end

there is no way to put an argument after "switchport protected" what do
I need to do to allow only those two vlan's ?

Thanks,

Richard
