VLAN
Virtual LAN (VLAN) is defined as a group of devices on one or more LANs that are configured so
that they can communicate as if they were attached to the same wire, when in fact they are located
on a number of different LAN segments. Because VLAN is based on logical instead of physical
connections, it is extremely flexible.
You can setup the Virtual LAN (VLAN) parameters in vlan command. The router support the
implementation of VLAN-to-PVC only for bridge mode operation, i.e., the VLAN spreads over both
the COE and CPE sides, where there is no layer 3 routing involved. The unit supports up to 8
active VLANs with shared VLAN learning (SVL) bridge out of 4096 possible VLANs specified in
IEEE 802.1Q.

support two types of VLAN, 802.11q and Port-Based. The IEEE 802.1Q defines the operation of
VLAN bridges that permit the definition, operation, and administration of VLAN topologies within a
bridged LAN infrastructure. Port-Based VLANs are VLANs where the packet forwarding decision is
based on the destination MAC address and its associated port.
802.11Q VLAN
Follow the following steps to configure 802.11q VLAN.
