MSTP Configuration

In this case, you can force the port to transit to the MSTP mode by performing the
mCheck operation on the port.
Similarly, a port on an RSTP-enabled switch operating as an upstream switch transits
to the STP-compatible mode when it has an STP-enabled switch connected to it. When
the STP-enabled downstream switch is then replaced by an MSTP-enabled switch, the
port cannot automatically transit to the MSTP operation mode. It remains in the
STP-compatible mode. In this case, you can force the port to transit to the MSTP mode
by performing the mCheck operation on the port.
1.4.1 Configuration Prerequisites
MSTP runs normally on the switch.
1.4.2 Configuration Procedure
You can perform the mCheck operation in the following two ways.
I. Performing the mCheck operation in system view
Follow these steps to perform the mCheck operation in system view:
To do ... Use the command ... Remarks
Enter system view
system-view
—
Perform the
mCheck operation
stp [ interface interface-list ] mcheck Required
II. Performing the mCheck operation in Ethernet port view
Follow these steps to perform the mCheck operation in Ethernet port view:
To do ... Use the command ... Remarks
Enter system view
system-view
—
Enter Ethernet port view
interface interface-type
interface-number
—
Perform the mCheck operation
stp mcheck
Required
1.4.3 Configuration Example
# Perform the mCheck operation on Ethernet2/0/1.
1) Configure in system view.
<H3C> system-view
[H3C] stp interface ethernet2/0/1 mcheck
2) Configure in Ethernet port view.
