stp mcheck
Description
Use the stp mcheck command to perform the mCheck operation globally or on a port.
If a port on a device running MSTP, RSTP, or PVST mode connects to an STP device, the port will
automatically migrate to the STP-compatible mode. It will not be able to migrate automatically back to the
MSTP, RSTP, or PVST mode, so it will remain working in the STP-compatible mode until the STP switch is
shut down or removed, or migrated to the MSTP, RSTP, or PVST mode. Then, you can perform an mCheck
operation to force the port to migrate to the MSTP, RSTP, or PVST mode.
The device works in STP-compatible, RSTP, MSTP, or PVST mode depending on the spanning tree mode
setting.
The stp mcheck command is effective only when the device works in MSTP, RSTP, or PVST mode.
Configured in system view, the setting takes effect globally.
Configured in Ethernet interface view, the setting takes only effect on the interface.
Configured in Layer 2 aggregate interface view, the setting takes effect only on the aggregate interface.
Configured on a member port in an aggregation group, the setting takes effect only after the port leaves
the aggregation group.
