Configuring Fast Start Mode

Table 17. Example 2. Trunk to 3Com SuperStackTM

	Parameter		Recommended Setting
	Port VLAN		Default - This parameter is ignored when
			using 3Com VLANs.
	Trunk Mode		3Com - Allows the switch to read the
			incoming VLAN tags.
	VLAN Binding		Static - This parameter is ignored when
			using 3Com VLANs.
	Automatic		Disable - This parameter is ignored when
	VLAN Creation		using 3Com VLANs.
	Table 18. Example 3. Trunk to Bay Networks System 5000TM
Parameter		Recommended Setting
Port VLAN		Default - Causes untagged packets to be
		assigned to the default VLAN.
Trunk Mode		IEEE-802.1Q- Causes the port to send frames
		using the IEEE-802.1Q format. This assumes
		that you have configured the Bay Networks
		switch to use IEEE-802.1Q VLAN tagging as
		well.
VLAN Binding		Bind to All - Binds the port to all VLANs
		known to the switch.
Automatic		Enable - Causes the switch to learn new VLAN
VLAN Creation		IDs that arrive at the port, and then bind the
		port to these VLANs.

Fast Start mode causes ports to begin forwarding traffic without waiting for the spanning tree negotiation to complete. Examples of situations where you may want to set a port to Fast Start mode are:

■End-station ports that do not need to participate in the full spanning tree negotiation

■Loop-free topologies that do not need spanning tree protocol to resolve redundant connections
