Re: VLAN 1 on switches

In the real world, I would shut it down unless you are using VLAN 1 (which
is not recommended). In the lab, I would not do a thing to it unless it is
required. If you need to use VLAN 1 for layer 3 purposes then you need to
make sure the SVI is up. Otherwise, just leave it alone. Curiosity killed
the cat (well, and made a career out of networking for me lol)
