With current port policy functionality, VLANs
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 VLANs 2 and 3 on
switch 2, but VLANs 2 and 3 are not carried
over the FDDI backbone to switch 1. The
members of VLANs 2 and 3 on switch 2 do
not become members of all VLANs 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
defvl
is on for the switch.
If
defvl
is off, the traf-
fic is dropped.
