Description
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.
Options
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
Required Privilege Level
routing—To view this statement in the configuration.
routing-control—To add this statement to the configuration.
