4.4.3 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 EFM modem
support the implementation of VLAN-to-PVC only for bridge mode operation, i.e., the VLAN
spreads over both the CO 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.

To active the VLAN function, move the cursor “ >> “ to mode and press enter. The products
support two types of VLAN, 802.1Q and Port-Based.
The 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.
4.4.3.1 Mode
User can choose two types of VLAN: 802.1Q Tag-Based VLAN or Port Based VLAN. When you
don’t use VLAN, set to Disable.
