spanning-tree
Use the spanning-tree global configuration command to enable Spanning Tree
Protocol (STP) on a VLAN. Use the no form of the command to disable STP on
a VLAN.
Syntax
spanning-tree [vlan stp-list]
no spanning-tree [vlan stp-list]
Syntax Description
vlan stp-list
(Optional) List of spanning-tree instances. Each spanning-tree instance is
associated with a VLAN ID. Valid IDs are from 1 to 1005. Enter each VLAN ID
separated by a space. Do not enter leading zeroes. Ranges are not supported.
Defaults
STP is enabled.
Command Modes
Global configuration.
Usage Guidelines
Disabling STP causes the VLAN or list of VLANs to stop participating in STP.
Ports that are administratively down remain down. Received Bridge Protocol
Data Units (BPDUs) are forwarded like other multicast frames. The VLAN does
not detect and prevent loops when STP is disabled.
