Operation Manual – MSTP
Quidway S3100 Series Ethernet Switches
A lower port priority value indicates a higher port priority. If all the ports of a switch have
the same port priority value, the port priorities are determined by the port indexes.
Changing the priority of a port will cause spanning tree regeneration.
You can configure port priorities according to actual networking requirements.
III. Configuration example
# Configure the port priority of Ethernet1/0/1 port in spanning tree instance 1 to be 16.
Configure in system view.
<Quidway> system-view
System View: return to User View with Ctrl+Z.
[Quidway] stp interface ethernet1/0/1 instance 1 port priority 16
Configure in Ethernet port view.
<Quidway> system-view
System View: return to User View with Ctrl+Z.
[Quidway] interface ethernet1/0/1
[Quidway-Ethernet1/0/1] stp instance 1 port priority 16

1.3.9 Point-to-point Link-Related Configuration

Refer to section 1.2.12 "Point-to-point Link-Related Configuration".

1.3.10 MSTP Configuration

Refer to section 1.2.13 "MSTP Configuration".

1.4 The mCheck Configuration

As mentioned previously, ports on an MSTP-enabled switch can operate in three
modes: STP, RSTP, and MSTP. A port on an MSTP-enabled switch automatically
toggles to the STP/RSTP mode when an STP-/RSTP-enabled switch is connected to it.
But when the STP-/RSTP-enabled switch is disconnected from the port, the port cannot
automatically toggle back to the MSTP mode and still remains in the STP/RSTP mode.
In this case, you can force the port to toggle to the MSTP mode by performing the
mCheck operation on the port.

1.4.1 Prerequisites

MSTP runs normally on the switch.
1.4.2 Configuration Procedure
You can perform the mCheck operation in the following two ways.
