8.3.5.6 MSTP Protocol
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.
Command Mode Description
stp clear-detected-protocol
PORTS
Bridge
Clears detected protocol and trys administrative proto-
col.
PORTS: select the port number.
8.3.5.7 Point-to-point MAC Parameters
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.
Command Mode Description
stp point-to-point-mac 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.
Command Mode Description
no stp point-to-point-mac PORT Bridge
Deletes point-to-point MAC configuration:
PORT: select the port number.
8.3.5.8 Edge Ports
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.
Command Mode Description
stp edge-port PORTS Bridge
Sets port edge mode:
PORTS: select the port number.
