equivalent. If edgeport is set to yes and an MSTP BPDU is received on the port,
indicating that another bridge is connected to the LAN, then the port will no
longer be treated as an edge port. The default is no. Edge ports are permitted to
make rapid transitions to the forwarding state, because they are known not to
be connected to another bridge and therefore cannot form part of a network
loop. Edge ports that are not configured as such must make slow transitions to
the forwarding state. For optimal convergence all edge ports should be
identified and have edgeport set to yes. A port should be set to edge port only
when it connects to a single end station.
The pointtopoint parameter specifies whether or not the port has a point-to-
point connection to another bridge. If auto is specified, then the status of point-
to-point link is determined automatically by the switch. If yes is specified, then
the port will be treated as a point-to-point LAN segment. The values yes, on
and true are equivalent. If no is specified, then the port will not be treated as a
point-to-point LAN segment. The values no, off and false are equivalent. If the
port is considered as a point-to-point port, then it is permitted to make rapid
transitions to the forwarding state, providing it receives an agreement message
from the bridge at the other end of the segment. A port should be set to point-
to-point only when it connects exactly one other bridge. The default is auto.
Example To set port priority of 16 for port 2 in the CIST, use the command:
set mstp cist port=2 priority=16
To set external port path cost of 120 for port 2 in the CIST, use the command:
set mstp cist port=2 extpathcost=120
To set internal port path cost of 200 for port 2 in the CIST, use the command:
set mstp cist port=2 intpathcost=200
To set port 2 in the CIST as edge port, use the command:
set mstp cist port=2 edgeport=yes
To set port 2 in the CIST as point to point link, use the command:
set mstp cist port=2 pointtopoint=yes
