Chapter 44: STP Commands

SPANNING-TREE PORTFAST
Syntax
spanning-tree portfast
Parameters
None
Mode
Port Interface mode
Description
Use this command to designate an edge port 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 to be an
edge port.
This command is used in conjunction with the SPANNING-TREE
PORTFAST BPDU-GUARD command.
Confirmation Command
“SHOW SPANNING-TREE” on page 666
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
