With current port policy functionality, 

VLAN

s

are not active, or “carried on” ports. Port 3-1
(slot 3 port 1) on switch 2, the backbone
port, is still a member of 

VLAN

s 2 and 3 on

switch 2, but 

VLAN

s 2 and 3 are not carried

over the 

FDDI

 backbone to switch 1. The

members of 

VLAN

s 2 and 3 on switch 2 do

not become members of all 

VLAN

s to which

the backbone port on switch 1 is assigned.
Rather, they become members of default

VLAN

 #1 on switch 1 if they do not match

any of switch 1’s existing 

VLAN

 policies and

if 

 is on for the switch.

If 

 is off, the traf-

fic is dropped.
