Spanning-Tree Link-Type - Planet SGSD-1022 User Manual

Default Setting
Disabled
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
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
Console(config)#interface ethernet 1/5
Console(config-if)#bridge-group 1 portfast
