I was wondering if there is a single command to clear a single network port's configuration? (wipe switchport, portsecurity,...)
1 Answer
In global configuration mode, typing default interface [the interface]
will clear the interface's configuration in the running-config.

Whenever you repurpose an interace, the safest action is to reset it to default. That way you can be sure to only have the settings you want.– JelmerSMay 23, 2013 at 12:17

11Beware, if you have commands on an interface that effect a port group (such as vlan maps on a 6500) the default command will remove those from the entire port group. May 23, 2013 at 12:21

3Yep, this is the easiest way. Additionally you might want to shutdown the port, 'default interface' doesn't do that for you.– Teun Vink ♦May 23, 2013 at 13:35

2@TeunVink, actually that depends if the interface is shutdown by default or not and this will vary depending on platform/version of IOS.– YLearnMay 23, 2013 at 18:38
