Verifying the PortFast Configuration | Cisco Systems RJ-45-to-AUX

Disabling PortFast on a CLI−Based IOS Switch

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

no spantree start−forwarding

Verifying the PortFast Configuration

To verify the PortFast configuration on a Set/Clear command−based switch, enter the following Privileged mode command:

show spantree <module/port>

To verify module 3 and port 8, do the following:

show spantree 3/8

Enabling UplinkFast on a Set/Clear Command−Based Switch

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

catalyst5000> (enable) set spantree uplinkfast ?

disable	Disable spanning tree uplink fast
enable	Enable spanning tree uplink fast

catalyst5000> (enable) set spantree uplinkfast enable ?

all−protocols	Enable uplink fast for all protocols
rate	Specify uplink fast rate
<cr>

catalyst5000> (enable) set spantree uplinkfast enable all−protocols ?

off	All	protocols	off
on	All	protocols	on

catalyst5000> (enable) set spantree uplinkfast enable all−protocols on VLANs 1−1005 bridge priority set to 49152.

The port cost and portvlancost of all ports set to above 3000. Station update rate set to 15 packets/100ms.

uplinkfast update packets enabled for all protocols. uplinkfast enabled for bridge.

Tip	The set spantree uplinkfast command has other options, such as adding a station update rate or
	adding the on or off syntax for all protocols. The station update rate value is the number of
	multicast packets transmitted per 100 milliseconds (by default, it is set to 15 packets per
	millisecond). For more information on how to execute a change in the station update rate, use the
	Help command on the console.

Disabling UplinkFast on a Set/Clear Command−Based Switch

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

catalyst5000> (enable) set spantree uplinkfast disable uplinkfast disabled for bridge.

Use clear spantree uplinkfast to return stp parameters to default.
