MSTP protocol has a backward compatibility. MSTP is compatible with STP and RSTP. If 
some other bridge runs with STP mode and send BPDU version of STP or RSTP, MSTP 
automatically changes to STP mode. STP mode can not be changed to MSTP mode 
automatically. If administrator wants to change network topology to MSTP mode, adminis-
trator has to clear previous detected protocol manually. 

To configure the protocol, use the following command. 

 

 

Bridge 

Clears detected protocol and trys administrative proto-
col. 
PORTS: select the port number. 

 

The internal sub layer service makes available a pair of parameters that permit inspection 
of, and control over, the administrative and operational state of the point-to-point status of 
the MAC entity by the MAC relay entity. 

To configure the point-to-point status, use the following command. 

  PORTS 

{auto | force-true | force-false} 

Bridge 

Sets point-to-point MAC: 
PORTS: select the port number 
auto: auto detect 
force-true: force to point-to-point MAC 
force-false: force to shared MAC (not point-to point 
MAC) 

 

True means, the MAC is connected to a point-to-point LAN, i.e., there is at most one 
other system attached to the LAN. False means, the MAC is connected to a non point-to-
point LAN, i.e., there can be more than one other system attached to the LAN. 

To delete the point-to-point configuration, use the following command. 

 PORT

Bridge 

Deletes point-to-point MAC configuration: 

PORT: select the port number. 

 

Edge ports are used for connecting end devices. There are no switches or spanning-tree 
bridges after the edge port. 

To configure edge port mode, use the following command. 

 PORTS Bridge 

Sets port edge mode: 
PORTS: select the port number.
