Configure The Mcheck Variable Of A Port - Huawei Quidway S3500 Series Operation Manual

Operation Manual - STP
Quidway S3500 Series Ethernet Switches
Note:
For a link aggregation, only the master port can be configured to connect with the
point-to-point link. If a port in auto-negotiation mode operates in full-duplex mode upon
negotiation, it can be configured to connect with the point-to-point link.
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 to which the port
belongs. Note that a temporary loop may be redistributed if you configure a port not
physically connected with the point-to-point link as connected to such a link by force.
By default, the parameter is configured as auto.

1.2.13 Configure the mCheck Variable of a Port

The port of an MSTP switch operates in either STP-compatible or MSTP mode.
Suppose a port of an MSTP switch on a switching network is connected to an STP
switch, the port will automatically transit to operate in STP-compatible mode. However,
the port stays in STP-compatible mode and cannot automatically transit back to MSTP
mode when the STP switch is removed. In this case, you can perform mCheck
operation to transit the port to MSTP mode by force.
You can use the following measure to perform mCheck operation on a port.
I. Configure in system view
Perform the following configuration in system view.
Table 1-20 Configure the mCheck variable of a port
Perform mCheck operation on a port.
II. Configure in Ethernet port view
Perform the following configuration in Ethernet port view.
Table 1-21 Configure the mCheck variable of a port
Perform mCheck operation on a port.
You can configure mCheck variable on a port with either of the above-mentioned
measures. For more about the commands, refer to the Command Manual.
