19.2.3.2 Enabling and Disabling MSTP
The STP protocol can be started in PVST or SSTP mode by default. You can stop it running when the
spanning-tree is not required.
Run the following command to set the STP to the MSTP mode:
Command Purpose
spanning-tree Enables STP in default mode.
spanning-tree mode mstp Enables MSTP.
Run the following command to disable STP:
Command Purpose
no spanning-tree Disables the STP.
19.2.3.3 Configuring MST Area
The MST area where the switch resides is decided by three attributes: configuration name, edit number, the
mapping relation between VLAN and MSTI. You can configure them through area configuration commands.
Note that the change of any of the three attributes will cause the change of the area where the switch resides.
In original state, the MST configuration name is the character string of the MAC address of the switch. The
edit number is 0 and all VLANs are mapped in the CIST (MST00). Because different switch has different MAC
address, switches that run MSTP are in different areas in original state. You can run spanning-tree mstp
instance instance-id vlan vlan-list to create a new MSTI and map the designated VLAN to it. If the MSTI is
deleted, all these VLANs are mapped to the CIST again.
Run the following command to set the MST area information:
Command Purpose
spanning-tree mstp namestring
Configures the MST configuration name.
string means the character string of the
configuration name. It contains up to 32
characters, capital sensitive. The default value is
the character string of the MAC address.
no spanning-tree mstp name Sets the MST configuration name to the default
value.
spanning-tree mstp revisionvalue
Sets the MST edit number.
value represents the edit number, ranging from 0 to
65535. The default value is 0.
no spanning-tree mstp revision Sets the MST edit number to the default value.
