Section V: Virtual LANs 449
This highly segmented configuration is useful in situations where traffic
generated by each end node or network segment connected to a port
on the switch needs to be kept separate from all other network traffic,
while still allowing access to an uplink to a WAN. Unicast traffic received
by the uplink port is effectively directed to the appropriate port and end
node, and is not directed to any other port on the switch.
The 802.1Q Multiple VLAN configuration is appropriate when the device
connected to the uplink port is IEEE 802.1Q compatible, meaning that it
can handle tagged packets.
When you select the 802.1Q-compliant VLAN mode, you are asked to
specify the Uplink VLAN port. You can specify only one uplink port. The
switch automatically configures the ports into the separate VLANs.
Note
The uplink VLAN is the management VLAN. Any remote
management of the switch must be made through the uplink VLAN.
Non-802.1Q
Compliant
Multiple VLAN
Mode
Unlike the 802.1Q-compliant VLAN mode, which isolates port traffic by
placing each port in a separate VLAN, this mode forms one VLAN with a
VID of 1 that encompasses all ports. Traffic isolation is established
through port mapping. The result, however, is the same. Ports are
permitted to forward traffic only to the designated uplink port and to no
other port, even when they receive a broadcast packet.
