Configuration Procedure - H3C S7500 Series Operation Manual

Operation Manual – MSTP
H3C S7500 Series Ethernet Switches
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 ...
Enter system view
Perform the
mCheck operation
II. Performing the mCheck operation in Ethernet port view
Follow these steps to perform the mCheck operation in Ethernet port view:
Enter system view
Enter Ethernet port view
Perform the mCheck operation
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.
Use the command ...
system-view
stp [ interface interface-list ] mcheck
To do ...
