Re: Removing sub interfaces

you can do a no interface sx.x

this will remove the interface although it takes a reload to fully remove it. If you do a sh ip int brief it still will show the subinterface, you must reload the box to get rid of this.

Re: Removing sub interfaces

Just use the no form of the command, to remove any commands in the running config. The same is the case with the sub interface. Because its a software created interface, you just need to use "no int sX.Y" to remove it.

When you give a show ip interface brief, you will still see all the deleted sub interfaces, but once you give a reload, of the router, this should clear up.

Hope that helps
