Release Information

Statement introduced in Junos OS Release 9.0 for EX Series switches.

Statement updated with enhanced ? (CLI completion feature) functionality in Junos OS Release 9.5 for EX Series switches.

Description

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

Note: 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.

Tip: 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.

Default
