and cannot automatically transit back to MSTP mode. In this case, you can
perform mCheck operation to transit the port to MSTP mode by force.
Related command: stp mcheck, stp mode.
Example
Set mcheck parameter of Ethernet5/0/3 in system view.
[SW7700]stp interface Ethernet5/0/3 mcheck
stp interface
point-to-point
Syntax
stp interface interface-list point-to-point { force-true |
force-false | auto }
undo stp interface interface-list point-to-point
View
System view
Parameter
interface-list: Ethernet port list, containing multiple Ethernet ports and
expressed as
interface _list = { { interface_type interface_num |
interface_name } [ to { interface_type interface_num | interface_name } ]
}&<1-10>. For detail descriptions of
interface_type, interface_num and
interface_name parameters, refer to the corresponding descriptions in Port
Command Manual. &<1-10> means that the preceding parameters can be
entered up to 10 times.
force-true: Indicates the Ethernet port connected to a point-to-point link.
force-false: Indicates the Ethernet port not connected to a point-to-point link.
auto: Configure to automatically check if the link to the Ethernet port is a
point-to-point link.
Description
■ Use the stp interface point-to-point command to configure a port (not)
to be connected to a point-to-point link in system view.
■ Use the undo stp interface point-to-point command to restore the
default state of the link to the Ethernet port.
By default, the parameter defaults to auto, that is, MSTP checks if the link to the
Ethernet port is a point-to-point link.
The port not connected with the point-to-point link cannot transit fast.
The master ports of the link aggregation and the ports operating in full-duplex
mode are connected to the point-to-point link. You are recommended to keep the
default settings and let MSTP detect the link state automatically.
This configuration takes effect on the CIST and all the MSTIs. The settings of a port
whether to connect the point-to-point link will be applied to all the STIs where the
port belongs. Note that a temporary loop may be redistributed if you configure a
