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.
NOTE:
You need to create a VLAN with the
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
These frames leave the device untagged.
•
If Tagging Mode is set to
Frames that enter the switch without a VLAN tag are tagged with the VLAN ID of the port they
entered through.

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 his or her own VLAN for privacy. The whole building has a
shared high-speed connection to the ISP.
