SET RSTP PORT
Syntax
set rstp port=port [default]
[portcost=auto|portcost]
[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).
default Returns the port’s RSTP settings to their default values.
This parameter should not be used with any other
command parameter. RSTP must be disabled in order
for you to use this parameter. To disable RSTP, use the
DISABLE RSTP command.
portcost Specifies the port’s port 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, for Auto-Detect, which automatically
sets port cost according to the speed of the port. Table
2 lists the ports cost with Auto-Detect.
