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
