Model 2160 Series Getting Started Guide
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 dif-
ferent LAN segments. Because VLAN is based on logical instead of physical connections, it is extremely flexi-
ble.
You can setup the Virtual LAN (VLAN) parameters in VLAN command. The Model 2160 supports 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.
The vlan command menu lists commands for setting up the line port. Move the cursor " >>" to vlan in the
setup menu and press Enter. The following menu displays:

To activate the VLAN function, move the cursor " >> " to mode and press Enter. The products support two
types of VLAN: 802.1Q and Port-Based.
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 for-
warding decision is based on the destination MAC address and its associated port.
Mode
You can choose from two types of VLANs: 802.1Q Tag-Based VLAN or Port Based VLAN. If you are not
going to use the VLAN function, set this option to Disable.
