LevelOne GSW-2600TXM manual Configuring Virtual LANs, Vlan Port Configuration

Forwarding*	Tree mode for the selected port. In this mode, ports skip the
	Blocked, Listening and Learning states and proceed straight to
	Forwarding.

*Since end-nodes cannot cause forwarding loops, they can be passed through the Spanning Tree state changes more quickly than allowed by standard convergence time. Fast Forwarding can achieve quicker convergence for end-node workstations and servers, and also overcome other STA related timeout problems. (Remember that Fast Forwarding should only be enabled for ports connected to an end-node device.)

2.5.4.Configuring Virtual LANs

You can use the VLAN configuration menu to assign any port on the switch to any of up to 256 Virtual LAN groups. In conventional networks with routers, broadcast traffic is split up into separate domains. Switches do not inherently support broadcast domains. This can lead to broadcast storms in large networks that handle traffic such as IPX or NetBEUI. By using IEEE 802.1Q-compliant VLANs, you can organize any group of network nodes into separate broadcast domains, thus confining broadcast traffic to the originating group. This also provides a more secure and cleaner network environment. For more information on how to use VLANs, see “Virtual LANs” on chapter 4. The VLAN configuration screens are described in the following sections.

2.5.4.1.VLAN Port Configuration

You can use the VLAN Port Configuration screen to configure GARP, the default VLAN identifier, default port priority, VLAN tagging on outgoing frames, GVRP and GMRP status, and filtering of incoming frames for VLAN groups to which this port does not belong.
