Enabling PortFast on a Set/Clear Command−Based Switch

To enable PortFast on a Set/Clear command−based switch port, use the following Privileged mode command:

set spantree portfast <module/port> enable

In this example, 2 is the module number and 1 is the port number:

catalyst5000> (enable) set spantree portfast ?

<trcrf>	Token Ring	TRCRF vlan number
<mod/port>	Module number and Port number(s)
bpdu−guard	Portfast	BPDU guard

catalyst5000> (enable) set spantree portfast 2/1 ?

disable	Disable port fast start
enable	Enable port fast start

catalyst5000> (enable) set spantree portfast 2/1 enable

Warning: Spantree port fast start should only be enabled on ports connected to a single host. Connecting hubs, concentrators, switches, bridges, etc. to a fast start port can cause temporary spanning tree loops. Use with caution.

Spantree port 2/1 fast start enabled.

Disabling PortFast on a Set/Clear Command−Based Switch

To disable PortFast on a Set/Clear command−based switch port, use the following Privileged mode command:

set spantree portfast <module/port> disable

In this example, 3 is the module number and 8 is the port number:

set spantree portfast 3/8 disable

Enabling PortFast on a CLI−Based IOS Switch

To enable PortFast on a Cisco IOS command−based switch, use this Interface Configuration mode command:

spantree start−forwarding
