VLAN Tagging
VLAN Tagging is a method of controlling the distribution of information on the network. The
ports on devices supporting VLAN Tagging are configured with the following parameters:
● Port VLAN ID
● Tagging Mode
The Port VLAN ID is the number of the VLAN to which the port is assigned. Untagged frames
(and frames tagged with VLAN 0) entering the port are assigned the port's VLAN ID. Tagged
frames are unaffected by the port's VLAN ID.
The Tagging Mode determines the behavior of the port that processes outgoing frames:
● If Tagging Mode is set to "Clear", the port transmits frames that belong to the port's VLAN
table. These frames leave the device untagged.
● If Tagging Mode is set to "IEEE-802.1Q", all frames keep their tags when they leave the
device. Frames that enter the switch without a VLAN tag will be tagged with the VLAN ID
of the port they entered through.
Multi VLAN Binding
Multi VLAN binding (Multiple VLANs per port) allows access to shared resources by stations
that belong to different VLANs through the same port. This is useful in applications such as
