# VLAN Group Configure

You can logically divide a physical interface into several virtual subinterfaces, each of which borrows the bandwidth it needs from the physical interface from which it stems. A subinterface is an abstraction that functions identically to a physical interface and is distinguished by 802.1Q VLAN tagging. The Security device directs traffic to and from a zone with a subinterface via its IP address and VLAN tag.

VLAN ID: Displays the identification number of the VLAN.

Action: Allows you to Remove the corresponding VLAN.
