SET RSTP PORT
Syntax
set rstp port=port|all [default]
[pathcost=pathcost]
[portpriority=portpriority][edgeport=yes|no]
[pointtopoint=yes|no|autoupdate]
[migrationcheck=yes|no]
Parameters
port Specifies the port you want to configure. You can
specify more than one port at a time. The ports can be
specified individually (e.g., 1,2,5,8), as a range (e.g., 2-
5), or both (e.g., 11-13,18). To configure all ports,
specify ALL.
default Returns the port’s RSTP settings to their default values.
This parameter performs the same function as the
RESET RSTP command.
pathcost Specifies the port’s path cost. The spanning tree
algorithm uses the cost parameter to decide which
port provides the lowest cost path to the root bridge
for that LAN. The range is 0 to 20 000 000. The default
setting is Auto-Detect, which automatically sets port
cost according to the speed of the port Table 2 lists
the ports cost with Auto-Detect.

100 Mbps 200 000
1000 Mbps 20 000
