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 Port VLAN ID and Tagging
Mode parameters.
The Port VLAN ID is the number of the VLAN to which the port is assigned.
Note:
You need to create a VLAN with the set vlan command before you can assign it to a port.
You can also create a VLAN by using the interface vlan command, followed by the
number of the VLAN (in other words., enter interface vlan 2 to create VLAN 2).
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 are tagged with the VLAN ID of
the port through which they entered.
Multi VLAN binding
Multi VLAN binding, also known as 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 multi-tenant networks, where each user has a personal VLAN for privacy. The whole
building has a shared high-speed connection to the ISP.
In order to accomplish this, the Branch Gateway enables multiple VLANs per port. The
available Port Multi-VLAN binding modes are:
Bound to Configured: The port supports all the VLANs configured in the switch
Statically Bound: The port supports VLANs manually configured on the port
The figure

on page 329 shows these binding modes.
