Unable to clear port-security sticky

Hi all,

I am using the command:

switchport port-security mac-address sticky to set port security.

On one of my IOS switch I am unable to clear the sticky MAC address using the command:

clear port-security sticky int fa 0/1.

Is there another way to achieve without having to upgrade IOS?

Thanks.

Yopu can do a show run for the port. The mac address show show up on the port. It should look like this: switchport port-security mac-address 0000.0000.0003. Just run a no switchport port-security mac-address 0000.0000.0003. That should do the trick.

The command given by Earnest basically removes the previously set/seen mac-add in that switch port.

Your port security is still enabled though provided that you've this command "switchport port-security" in place.

The port security sticky option is still enabled if you have this command "switchport port-security mac-address sticky" in the switch port.

simply put 'no' in front of that command

no switchport port-security mac-address sticky [mac-address]

it will clear the captured mac

Thanks Ernest.

What exactly will that command do? I dont want to shut off port security, just wanted to clear the MAC address so the port does not shutdown when the next machine is plugged in.
