Re: VLAN 1 on switches

The interface is the SVI (a layer 3 virtual interface available if you
want to assign an IP address), and depending on the version/platform
it may be shut by default or not. If you aren't using it, best
practice is to keep it shut down. It will not affect your trunking at
all if it shutdown.
