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.
