Chapter 40: RSTP Commands
546 Section VI: Spanning Tree Protocols
SPANNING-TREE PORTFAST
Syntax
spanning-tree portfast
Parameters
None.
Mode
Port Interface mode
Description
Use this command to designate edge ports on the switch. Edge ports are
not connected to spanning tree devices or to LANs that have spanning
tree devices. As a consequence, edge ports do not receive BPDUs. If an
edge port starts to receive BPDUs, it is no longer considered an edge port
by the switch.
Confirmation Command
“SHOW RUNNING-CONFIG” on page 129
Example
This example configures port 17 as an edge port:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.17
awplus(config-if)# spanning-tree portfast
