Because 3-1 (slot 3 port 1)
on switch 1, the backbone port, is
a member of VLANs 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 VLANs 2 and 3 on
switch 1 become members of all VLANs to
which the backbone port on switch 2 is
assigned. Switch 1’s VLAN 2 (Device B) and
switch 1’s VLAN 3 (Device C) are active on slot
3 port 1, so Devices B and C become members
of VLANs 2 and 3 on switch 2 (the VLANs to
which the backbone port is assigned).
Because 3-1 (slot 3 port 1) on switch 2, the
backbone port, is a member of VLANs 2 and 3
on switch 2, VLANs 2 and 3 are active, or “car-
ried on” 3-1. They are carried over the FDDI
backbone to switch 1. The members of VLANs
2 and 3 on switch 2 become members of all
VLAN
s to which the backbone port on switch 1
is assigned. Switch 2’s VLAN 2 (Device A) and
switch 2’s VLAN 3 (Device D) are active on slot
3 port 1, so Devices A and D become members
of VLANs 2 and 3 on switch 1 (the VLANs to
which the backbone port
is assigned).
