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 190.
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.
5. After making changes, type R until you return to the Main Menu. Then
type S to select Save Configuration Changes.
Displaying
MSTP Port
Settings and
Status
The MSTP Port Parameters menu, shown in Figure 86 on page 236, has
two selections for displaying a variety of MSTP port information. The two
menu selections are described below. (To display the menu, from the

This selection displays a menu that contains the current port settings for
the following MSTP parameters:
❑ Edge-Port
❑ Point-to-Point Port
❑ External or Internal Port Cost
❑ Port Priority
3 - Display MSTP Port State
This selection displays a menu that contains the following MSTP
operating status for a port:
❑ State - Identifies the MSTP state of the port. Possible states are:
discarding, learning, and forwarding. A state of disabled means
the port has not established a link with its end node.
❑ MSTI-ID - The MSTI ID of the VLAN containing the port. (The MSTI
ID for a regional boundary port is always 0, even if the VLAN
containing the port has been associated with a MSTI other than
CIST.)
