Examples: Configuring PortFast Edge on a Specified Interface
This example shows how to enable edge behavior on GigabitEthernet interface 1/0/1:
Switch# configure terminal
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# spanning-tree portfast edge
Switch(config-if)# end
Switch#
This example shows how to verify the configuration:
Switch# show running-config interface gigabitethernet1/0/1
Building configuration...
Current configuration:
!
interface GigabitEthernet
1/0/1
no ip address
switchport
switchport access vlan 200
switchport mode access
spanning-tree portfast edge
end
This example shows how you can display that port GigabitEthernet 1/0/1 is currently in the edge state:
Switch# show spanning-tree vlan 200

Examples: Configuring a PortFast Network Port on a Specified Interface
This example shows how to configure GigabitEthernet interface 1/0/1 as a network port:
Switch# configure terminal
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)#
spanning-tree portfast network
Switch(config-if)# end
Switch#
This example shows how to verify the configuration:
Switch#
