General VLAN operation

  • A VLAN is composed of multiple ports operating as members of the same subnet or broadcast domain.

  • Ports on multiple devices can belong to the same VLAN.

  • Traffic moving between ports in the same VLAN is bridged (or switched).

  • Traffic moving between different VLANs must be routed.

  • A static VLAN is an 802.1Q-compliant VLAN, configured with one or more ports that remain members regardless of traffic usage.

  • A dynamic VLAN is an 802.1Q-compliant VLAN membership that the switch temporarily creates on a port to provide a link to another port either in the same VLAN on another device.
