mstp sets the switch in IEEE802.1s MSTP mode; stp sets the switch in IEEE802.1D STP mode;
rstp sets the switch in IEEE802.1D RSTP mode.
Command mode:
Global Mode
Default:
The switch is in the MSTP mode by default.
Usage Guide:
When the switch is in IEEE802.1D STP mode, it only sends standard IEEE802.1D BPDU and TCN
BPDU. It drops any MSTP BPDUs.
Example:
Set the switch in the STP mode.
Switch(config)#spanning-tree mode stp

spanning-tree mst configuration” restores the attributes of the MSTP to their default values.
Command mode:
Global Mode
Default:
The default values of the attributes of the MSTP region are listed as below:
Attribute of MSTP
Default Value
Instance

Revision

Usage Guide:
Whether the switch is in the MSTP region mode or not, users can enter the MSTP mode, configure
the attributes, and save the configuration. When the switch is running in the MSTP mode, the
system will generate the MST configuration identifier according to the MSTP configuration. Only if
the switches with the same MST configuration identifier are considered as in the same MSTP
region.
Example:
Enter MSTP region mode.
