VLAN This section is available in this screen only when you select Bridge in
the Mode field.
VLAN Active Select this option to enable VLAN multiplexing of multiple protocols
over a single virtual circuit. You need to assign a VLAN ID and priority
level to traffic through each WAN connection. All WAN connections
share one MAC address. This allows the backbone switch to classify
and service traffic based on the VLAN tag, instead of the MAC address.
Otherwise, disable VLAN multiplexing and each WAN connection has
its own MAC address.
Note: This field is only configurable for the first WAN connection.
When you change the setting here, all existing WAN
connections will be removed except for the first WAN
connection.
VLAN ID Enter a VLAN ID number for traffic that goes through this connection.
Priority Enter a priority level for traffic that goes through this connection.
Apply Click this to save the changes.
Reset Click this to begin configuring this screen afresh.
