Table 19 lists the RSTP port costs with Auto-Detect when the port
is part of a port trunk.
3- Port External Path Cost
The port cost of the port if the port is connected to a bridge which
is a member of another MSTP region or is running STP or RSTP. The
range is 0 to 200,000,000. The default setting is 200,000.
4 - Point-to-Point
This parameter defines whether the port is functioning as a point-
to-point port. The possible settings are Yes, No, and Auto-Detect.
For an explanation of this parameter, refer to ”Point-to-Point and
Edge Ports” on page 255.
5 - Edge Port
This parameter defines whether the port is functioning as an edge
port. The possible settings are Yes and No. For an explanation of
this parameter, refer to ”Point-to-Point and Edge Ports” on page
255.
C - Check Migration to MSTP on Selected Ports (MCHECK)
The MCHECK parameter is displayed only when MSTP is enabled.
This parameter resets an MSTP port, allowing it to send MSTP
BPDUs. When an MSTP bridge receives STP BPDUs on an MSTP
port, the port transmits STP BPDUs. The MSTP port continues to
transmit STP BPDUs indefinitely. Type C to reset the MSTP port to
transmit MSTP BPDUs.
Each time an MSTP 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.
