If you have your vtp domain set to NULL
and have all the switches in the switch fabric/enterprise
configured for transparent mode.
This takes care of really worrying about vtp prunage/pruning
right or wrong?
But with dot1q encap you will still have the vlan 1 traffic
traversing the trunks......
switchport mode trunk remove vlan1
Is this correct???
Or all wrong?
Additionally lets say you have created an configured
a vlan and it's respective SVI as opposed to using
vlan 1 for MGT.
You have also gone out of your way to ensure that
interface Vlan1 on all switch SVIs do not have ip addresses
configured and they are shut down.
If you have physical switchports/ports on these switches
that DO NOT have a specific vlan MEMBERSHIP via the
"switchport access vlan" command then they default to
Same goes for trunk ports if you DO NOT specific the
I am just trying to keep this all straight.
The one thing I have never had conclusive answers for is
can you somehow change the DEFAULT VLAN to something
other than Vlan 1 in global config or something?
You can obviously take care of Vlan 1 at layer 3
on devices by disabling/de-configuring it if you will but
can you really do anything about it at Layer 2?
Thats all I got.
