14. Check to see that the VLAN was created correctly and that it contains
the appropriate ports.
15. Press Esc or type R to return to the Virtual LAN Definitions menu.
You can repeat this procedure to create additional VLANs.
Note
When you create a new VLAN, ports designated as untagged ports
of the new VLAN are automatically removed from their current
VLAN assignment. For example, if you are creating a new VLAN on a
switch that contains only the Default VLAN, the ports that you
specify as untagged ports of the new VLAN are automatically
removed from the Default VLAN.
Tagged ports are not removed from any current VLAN assignments
because tagged ports can belong to more than one VLAN at a time.
