In the above example, there are three different VLANs and each
port can transmit packets on one of them according to their
Port VLAN ID (PVID). However, a port can receive packets on all
VLANs (VID) that it belongs to. The assignments are as follows:
Transmit on VLAN #
Member of VLAN #
Port
PVID
VID
Ports
Port 1
1
1 1,2,3,7
Port 2

Port 3

Port 7

Port 11

2 11,12,7
Port 12

Table 5-2. Example of possible VLAN assignments
The server attached to Port 7 is shared by VLAN 1 and VLAN 2
because Port 7 is a member of both VLANs (it is listed as a
member of VID 1 and 2). Since it can receive packets from both
VLANs, all ports can successfully send packets to it to be
printed. Ports 1, 2 and 3 send these packets on VLAN 1 (their
PVID=1), and Ports 11 and 11 send these packets on VLAN 2
(PVID=2). The third VLAN (PVID=3) is used by the server to
transmit files that had been requested on VLAN 1 or 2 back to
the computers. All computers that use the server will receive
transmissions from it since they are all located on ports which
are members of VLAN 3 (VID=3).
VLANs Spanning Multiple Switches
VLANs can span multiple switches as well as your entire
network. Two considerations to keep in mind while building
VLANs of this sort are whether the switches are IEEE 802.1Q-
