stp mcheck
Syntax
stp mcheck
View
System view, Ethernet interface view, Layer 2 aggregate interface view
Default Level
2: System level
Parameters
None
Description
Use the stp mcheck command to carry out the mCheck operation globally or on the current port.
If a port on a device running MSTP (or RSTP) connects to a device running STP, this port will
automatically migrate to the STP-compatible mode. However, it will not be able to migrate
automatically back to the MSTP (or RSTP) mode, but will remain working in the STP-compatible mode
under the following circumstances:
z
The device running STP is shut down or removed.
z
The device running STP migrates to the MSTP (or RSTP) mode.
By then, you can perform an mCheck operation to force the port to migrate to the MSTP (or RSTP)
mode.
Note that:
z
The device works in STP-compatible mode, RSTP mode or MSTP mode depending on the MSTP
mode setting.
z
The stp mcheck command is meaningful only when the device works in RSTP or MSTP mode.
z
Configured in system view, the setting takes effect globally; configured in Ethernet interface view,
the setting takes effect on the current interface only; configured in port group view, the setting
takes effect on all member ports in the port group.
z
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 can take effect only
after the port leaves the aggregation group.
