Each time an RSTP port is reset by receiving STP BPDUs, you need
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.
Point-to-Point
This parameter defines whether the port is functioning as a point-
to-point port. The default setting is Auto Detect, which sets port
cost depending on the speed of the port. Default values are 100
for a 10 Mbps port, 10 for a 100 Mbps port, and 4 for a 1 Gbps port.
For an explanation of this parameter, refer to Point-to-Point Ports
and Edge Ports on page 234.
Edge Port
This parameter defines whether the port is functioning as an edge
port. For an explanation of this parameter, refer to Point-to-Point
