Lucent Technologies P550 Configuring Fast Start Mode

	Configuring the Cajun P550 Switch (Layer 2 & Layer 3)
Table 3-12.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 VLAN	Disable - This parameter is ignored when using 3Com VLANs.
Creation
Table 3-13.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 VLAN	Enable - Causes the switch to learn new VLAN IDs that arrive
Creation	at the port, and then bind the port to these VLANs.

Configuring Fast Start Mode

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

To enable Fast Start for ports on a module associated with a selected bridge:

1.In the System Configuration section of the Web Agent window, click Modules & Ports. The Module Information dialog box opens.

2.In the Switch Ports column, click on the switch port number listed for the selected module. The Switch Ports dialog box opens.
