Set Mcheck Of The Specified Port - Huawei Quidway S3000 Series Operation Manual

Operation Manual - STP
Quidway S3000 Series Ethernet Switches
You can use the following command to configure a specified port to be connected to a
point-to-point link.
Perform the following configurations in Ethernet port view.
Table1-14 Configure a specified port to be connected to a point-to-point link
Configure a specified port to be connected to a point-to-point link
Configure a specified port not to be connected to a point-to-point
link
Configure RSTP to automatically detect if the port is connected to a
point-to-point link.
Configure the port to be automatically detected if it is connected to
a point-to-point link, as defaulted.
The two ports connected via the Point-to-Point link can enter the forwarding state
rapidly by transmitting synchronous packets, so that the unnecessary forwarding delay
can be reduced. If this parameter is configured to be auto mode, RSTP can
automatically detect if the current Ethernet port is connected to a Point-to-Point link.
Note that, for an aggregated port, only the master port can be configured to connect
with the point-to-point link. After auto-negotiation, the port working in full duplex can
also be configured to connect with such link.
You can manually configure the active Ethernet port to connect with the Point-to-Point
link. However, if the link is not a point-to-point link, the command may cause a system
problem, and therefore it is recommended to set it as auto mode.
By default, this parameter is configured to auto, namely in auto mode.

1.2.15 Set mCheck of the Specified Port

Suppose there are some switches running STP and some other switches running
RSTP on a switching network. RSTP is STP-compatible. In a relatively stable network,
though the bridge running STP has been removed, the port of the switch running RSTP
is still working in STP-compatible mode. You can use the following command to
manually command the port to work in RSTP mode. This command can only be issued
if the bridge runs RSTP in RSTP mode and has no effect in the STP-compatible mode.
You can use the following command to configure mCheck of a specified port.
Perform the following configurations in Ethernet port view.
