Parameters

vlan vlan-id-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN or a range of VLANs in the form of vlan-id1 [ to vlan-id2 ]. The value for vlan-id2 must be equal to or greater than the value for vlan-id1. The value range for the vlan-id argument is 1 to 4094. If you do not specify this option, the command globally enables or disables the spanning tree feature (VLANs are not included).

Usage guidelines

When you enable the spanning tree feature, the device operates in STP, RSTP, PVST, or MSTP mode, depending on the spanning tree mode setting.

When you enable the spanning tree feature, the device dynamically maintains the spanning tree status of VLANs, based on received configuration BPDUs. When you disable the spanning tree feature, the device stops maintaining the spanning tree status.

Examples

# In PVST mode, globally enable the spanning tree feature, and enable the spanning tree feature in VLAN 2.
