MSTP Configuration Commands
1-9
The MSTP revision level, along with the MST region name and the VLAN mapping
table, determines the MST region a switch belongs to.
Related commands: instance, region-name, check region-configuration,
vlan-mapping modulo, active region-configuration.
Examples
# Set the MSTP revision level of the MST region to 5.

1.1.9 stp
Syntax
stp { enable | disable }
undo stp
View
System view, Ethernet port view
Parameters
enable: Enables MSTP globally or on a port.
disable: Disables MSTP globally or on a port.
Description
Use the stp command to enable/disable MSTP globally or on a port.
Use the undo stp command to revert to the default MSTP state globally or on a port.
By default, MSTP is disabled globally and on a port.
By default, once MSTP is enabled globally, it is enabled on a port.
After MSTP is enabled, the actual operation mode, which can be STP-compatible mode,
RSTP-compatible mode, or MSTP mode, is determined by the protocol mode
configured by users. A switch becomes a transparent bridge if MSTP is disabled.
After being enabled, MSTP maintains spanning trees by processing configuration
BPDUs of different VLANs. After being disabled, it stops maintaining spanning trees.
Related commands: stp mode, stp interface.
Examples
# Enable MSTP globally.
