350 Asanté IntraCore 36000 Series
Usage Guidelines
This command is used to enable/disable the fast spanning-tree mode for the selected port. In this mode,
ports skip the Discarding 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 a LAN segment
that is at the end of a bridged LAN or for an end-node device.)
This command is the same as spanning-tree edge-port, and is only included for backward compatibility with
earlier products. Note that this command may be removed for future software versions.
Example
The following is sample output from the spanning-tree portfast command.
Console(config)#interface ethernet 1/5
Console(config-if)#bridge-group 1 portfast
Console(config-if)#

Usage Guidelines
This command defines the priority for the use of a port in the Spanning Tree Algorithm. If the path cost for all
ports on a switch are the same, the port with the highest priority (that is, lowest value) will be configured as
an active link in the spanning tree.
Where more than one port is assigned the highest priority, the port with lowest numeric identifier will be
enabled.
