1.5 Performing mCheck Operation

Ports on an MSTP-enabled switch can operate in three modes: STP-compatible,
RSTP-compatible, and MSTP.
A port on an MSTP-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 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.
Similarly, a port on an RSTP-enabled switch operating as an upstream switch turns 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-compatible mode. It remains in the
STP-compatible mode. In this case, you can force the port to transit to the
MSTP-compatible mode by performing the mCheck operation on the port.

1.5.1 Configuration Prerequisites

MSTP runs normally on the switch.

1.5.2 Configuration Procedure

You can perform the mCheck operation in the following two ways.
