VLANs
Remember that a created VLAN is unused until it is mapped to a switch port
or ports and that all ports are always in VLAN 1 unless set otherwise.
After you create the VLANs that you want, you use the show vlan com-
mand to see the configured VLANs. However, notice that, by default, all
ports on the switch are in VLAN 1. To change that, you need to go to each
interface and tell it what VLAN to be a part of:
