Stp Mode - 3Com S7906E Command Reference Manual

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.
In a switched network, if a port on the device running MSTP (or RSTP) connects to a device running
STP, this port will automatically migrate to the STP-compatible mode. However, if the device running
STP is removed, the port will not be able to migrate automatically to the MSTP (or RSTP) mode, but will
remain working in the STP-compatible mode. In this case, you can perform an mCheck operation to
force the port to migrate to the MSTP (or RSTP) mode.
Note that:
The stp mcheck command is meaningful only when the device works in the MSTP (or
RSTP-compatible) mode, not in the STP-compatible mode.
Configured in system view, the setting takes effect globally; configured in port view, the setting
takes effect on the current port only.
Configured in Layer-2 aggregate port view, the setting takes effect only on the aggregate port.
Configured on the member port in an aggregation group, the setting can take effect only after the
port leaves the aggregation group. For detailed information about link aggregation, refer to Link
Aggregation Configuration in the Access Volume.
