vlan (MSTP)


EX Series

Hierarchy Level


Configure the VLANs for a Multiple Spanning Tree Instance (MSTI) or VSTP instance.


When you configure VSTP with the set prototocol vstp vlan all command, vlan-id 1 is excluded to be compatible with Cisco PVST+. If you want vlan-id 1 to be included in VSTP, you must set it separately with the set protocol vstp vlan 1 command.


To display a list of all configured VLANs on the system, including VLANs that are configured but not committed, type ? after vlan or vlans in your configuration mode command line. Note that only one VLAN is displayed for a VLAN range.


vlan-name—Name of the VLAN.

vlan-id—The VLAN identifier associated with the MSTI.

vlan-id-range—Range of VLAN identifiers associated with the MSTI in the form minimum-vlan-id-maximum-vlan-id. VLAN identifier ranges are not supported for VSTP.

  • Range: 1 through 4096
