Everything else was "defaulted". Marko, I just tested default interface command on my 6500, and it *does* retain the shutdown/noshutdown state of the interface. Everything else was “defaulted”.

You can also use the range directive to reset configs on a whole mess of ports. Router(config)#default int range f0/0/0 - 4 Or something like that.

By default, switchports are not shutdown and defaulting will make them come up, possibly in the wrong VLAN. Of course, STP should not make this too dangerous, but it's a good thing to be aware of. What I usually do is: default interface X interface X shutdown ! whatever else I need to do Beware of it on production switches, though!
