Slot 2 Port 2Slot 3 Port 1 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.
With current port poli-
cy functionality, VLANs
are not active, or “carried
on” ports. Port 3-1 (slot 3 port 1) on
switch 1, the backbone port, is still a mem-
ber of VLANs 2 and 3 on switch 1, but VLANs
2 and 3 are not carried over the FDDI back-
bone to switch 2. The members of VLANs 2
and 3 on switch 1 do not become members
of all VLANs to which the backbone port on
switch 2 is assigned. Rather, they become
members of default VLAN #1 on switch 2 if
they do not match any of switch 2’s existing
VLAN policies and if defvl is on for the
switch. If defvl is off, the traffic is dropped.
