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

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 Creation

Enable - Causes the switch to learn new VLAN
IDs that arrive at the port, and then bind the
port to these VLANs.
