bridge-group portfast

Use this command to set a port to fast forwarding. Use the 

no

 form to 

disable fast forwarding.

Syntax 

bridge-group

 

bridge-group

 

portfast

no bridge-group

 

bridge-group

 

portfast

bridge-group

 - Bridge group index (bridge 1.)

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 Blocked, Listening 
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 an 
end-node device.) 

Example

Console(config)#interface ethernet 1/5
Console(config-if)#bridge-group 1 portfast
Console(config-if)#
