4 Spanning Tree Commands 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 Console(config-if)# Related Commands spanning-tree edge-port (4-156) spanning-tree link-type This command configures the link type for Rapid Spanning Tree and Multiple Spanning Tree. Use the no form to restore the default. Syntax spanning-tree link-type {auto | point-to-point | shared} no spanning-tree link-type • auto - Automatically derived from the duplex mode setting. • point-to-point - Point-to-point link. • shared - Shared medium. Default Setting auto Command Mode Interface Configuration (Ethernet, Port Channel) Command Usage • Specify a point-to-point link if the interface can only be connected to exactly one other bridge, or a shared link if it can be connected to two or more bridges. • When automatic detection is selected, the switch derives the link type from the duplex mode. A full-duplex interface is considered a point-to-point link, while a half-duplex interface is assumed to be on a shared link. 4-157
