- [Instructor] Cisco switches have one VLAN by default
which is VLAN one.
All of the ports on the switch
are assigned to VLAN one also by default.
I'm going to show you how the VLAN one is displayed
on the Cisco switch.
I'm going to go ahead and click on the west switch,
click on the CLI, hit enter on the keyboard.
I'm going to go ahead and expand the window.
I type console, C O N S O L E zero, E N A for enable.
S E C R E T one, that's the enable password.
And then I go ahead, issue the command show vlan brief.
The output of the show vlan brief displays my VLAN,
that default VLAN one.
It is active and you can see that all of the ports
on the switch have been assigned to this VLAN.
I cannot change the name of this VLAN, I'll show you.
If I go config t, I go into VLAN one,
and I try to change its name.
Let's say I want to call it wireless.
Notice it says that the default VLAN
may not have its name changed.
So Cisco switches will always have the one VLAN by default
with a name of default.
