Avaya P334T-ML User’s Guide
In Figure 11.2, the switch has three separate VLANs: Sales, Engineering, and 
Marketing (Mktg). Each VLAN has several physical ports assigned to it with PC’s 
connected to those ports. When traffic flows from a PC on the Sales VLAN for 
example, that traffic is only forwarded out the other ports assigned to that VLAN. 
Thus, the Engineering and Mktg VLANs are not burdened with processing that 
traffic.

VLAN Switching and Bridging
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 multi-tenant networks, where each user has his a VLAN for
