on switch 1, the backbone port, is
a member of
VLAN
s 2 and 3 on switch 1,
VLAN
s 2 and 3 are active, or “carried on” 3-1.
They are carried over the
FDDI
backbone to
switch 2. The members of
VLAN
s 2 and 3 on
switch 1 become members of all
VLAN
s to
which the backbone port on switch 2 is
assigned. Switch 1’s
assigned. Switch 1’s
VLAN

Because 3-1 (slot 3 port 1) on switch 2, the

VLAN
s 2 and 3
on switch 2,
VLAN
s 2 and 3 are active, or “car-

backbone to switch 1. The members of
VLAN
s

s to which the backbone port on switch 1
is assigned. Switch 2’s
VLAN
