It uses the current MAC that is plugged into interface

To configure a new VLAN:

Definition
Step 1.
To configure a new VLAN:

a. From configuration mode, use the vlan vlan-id global configuration command to create the VLAN and move the user into VLAN configuration mode.

b. (Optional) Use the name name VLAN subcommand to list a name for the VLAN. If not configured, the VLAN name is VLANZZZZ, where ZZZZ is the four-digit decimal VLAN ID.

Step 2.
To configure a VLAN for each access interface:

a. Use the interface command to move into interface configuration mode for each desired interface.

b. Use the switchport access vlan id-number interface subcommand to specify the VLAN number associated with that interface.

c. (Optional) To disable trunking so that the switch will not dynamically decide to use trunking on the interface, and it will remain an access interface, use the switchport mode access interface subcommand
