5 - 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
Ports and Edge Ports on page 234.
C - Check Migration To RSTP on Selected Ports (MCHECK)
The MCHECK parameter appears only when MSTP is enabled. 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.
7. After making changes, type R until you return to the Main Menu. Then
type S to select Save Configuration Changes.
