DES-7200 Configuration Guide Chapter 10 MSTP Configuration
10-23
10.3.2 Enabling and
Disabling the
Spanning Tree
Protocol
By default, DES-7200 series runs the MSTP protocol.
The spanning tree protocol is disabled on the device by default.
To enable the spanning tree protocol, execute the following command in the
privileged mode:
Command Function
DES-7200# configure terminal
Enter the global configuration mode.
DES-7200(config)# spanning-tree
Enable the spanning tree protocol.
DES-7200(config)# end
Return to the privileged EXEC mode.
DES-7200# show spanning-tree
Verify the configuration.
DES-7200# copy running-config
startup-config
Save the configuration.
To disable the spanning tree protocol, use the no spanning-tree command in
the global configuration mode.
10.3.3 Configuring the
Spanning Tree
Mode
According to the 802.1-related protocols, it is not necessary for administrators
to set much for three versions of the spanning tree protocols such as the STP,
RSTP and MSTP. These versions are compatible with one another naturally.
However, given that some manufacturers will not develop the spanning tree
protocol by standards, it may cause some compatibility problem. Hence, we
provide a command to facilitate administrators to switch to the lower version of
the spanning tree protocol for compatibility when they detect that this device is
not compatible with that of other manufacturers.
Note: When you switch to the RSTP or STP version from the MSTP version, all
information about MSTP Region will be cleared.
The default mode of the device is MSTP.
To enable the spanning tree protocol, execute the following command in the
privileged mode:
Command Function
DES-7200# configure terminal
Enter the global configuration mode.
