VLAN

The following sections describe how to configure and query VLANs, hybrid interfaces, access interfaces, trunk interfaces, and VLANIF interfaces.

A local area network (LAN) can be divided into several logical LANs. Each logical LAN is a broadcast domain, which is called a virtual LAN (VLAN). To put it simply, devices on a LAN are logically grouped into different LAN segments, regardless of their physical locations. VLANs isolate broadcast domains on a LAN.

• VLAN
  You can create, query, modify, and delete VLANs. In addition, you can create VLANs in a batch.
• Hybrid Interface
  You can query, modify, or delete the configuration of a hybrid interface.
• Access Interface
  You can query, modify, or delete the configuration of an access interface.
• Trunk Interface
  You can query, modify, or delete the configuration of a trunk interface.
• VLANIF Interface
  When a switch needs to communicate with the devices at the network layer, you can create a logical interface based on a VLAN on the switch, namely, a VLANIF interface. The VLANIF interface is a configured interface and does not exist physically.
