Is this creating an error? Because the delete call seems to be working just fine for switchport interfaces.

Ignore this commit for now, i am still investigating an issue that may have some relation to this. One thing that caught our attention is that we configure icmp settings on interfaces that have no addressing configured. I will probably change this and push into this PR.
