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?
simply put 'no' in front of that command
no switchport port-security mac-address sticky [mac-address]
it will clear the captured mac
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.
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.
