Chapter 26: Multiple VLAN Modes
610 Section V: VLANs
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, but still
have access to an uplink port 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.
