VLAN Terms

13-6 VLAN Operation and Network Applications

Default VLAN The VLAN to which all ports are assigned upon initialization.

The Default VLAN has a VLAN ID of 1 and cannot be deleted or

renamed.

Forwarding List A list of the ports on a particular device that are eligible to

transmit frames for a selected VLAN.

Port VLAN List A per port list of all eligible VLANs whose frames can be

forwarded out one specific port and the frame format (tagged or

untagged) of transmissions for that port. The Port VLAN List

specifies what VLANs are associated with a single port for frame

transmission purposes.

Filtering Database A database structure within the switch that keeps track of the

associations between MAC addresses, VLANs, and interface

(port) numbers. The Filtering Database is referred to when a

switch makes a forwarding decision on a frame.

1Q Connection

(previously referred to as a

1Q Trunk)

A connection between 802.1Q switches that passes only traffic

with a VLAN Tag Header inserted in each frame. All VLANs in

the port’s Port VLAN List are configured to transmit all frames

as tagged frames. The port will drop all incoming frames that do

not have a VLAN tag.

1D Connection This is a reference to a connection from a switch that passes only

untagged traffic. By default, a port designated to pass only

untagged frames has all VLANs on its Port VLAN List and is

configured to transmit all frames as untagged frames.

NOTE: The user cannot configure an interface to

receive only untagged frames.

Per VLAN Spanning Tree

Protocol (PVSTP)

A protocol used to create a separate Spanning Tree topology for

each VLAN configured in a switch.

Quick Convergence STP

(QCSTP)

A protocol that is compatible with PVSTP and provides

automatic topology changes at 1/10th the speed of PVSTP.

QCSTP is also backwards compatible with IEEE 802.1D.
