C - Check Migration To RSTP on Selected Ports (MCHECK)
This parameter resets a RSTP port, allowing it to send RSTP BPDUs.
When an RSTP bridge receives STP BPDUs on an RSTP port, the
port transmits STP BPDUs. The RSTP port continues to transmit
STP BPDUs indefinitely. Type C to reset the RSTP port to transmit
RSTP BPDUs.
Each time a RSTP port is reset by receiving STP BPDUs, you need
to type C to reset the RSTP port, allowing it to send RSTP BPDUs.
Note
MCHECK is only valid when the RSTP mode is enabled. This option
does not apply when the switch is in STP mode.
