SET RSTP PORT
Syntax
set rstp port=port|all [default]
[portcost=portcost|auto]
[portpriority=portpriority][edgeport=yes|no]
[pointtopoint=yes|no|autoupdate]
[migrationcheck=yes|no]
Parameters
port Specifies the port (that is, slot.port) you want to
configure. You can specify more than one port at a
time. To configure all ports, enter ALL. (For
information on how to enter ports, refer to Specifying
Ports on page 17.)
default Returns the port’s RSTP settings to their default values.
This parameter performs the same function as the
RESET RSTP command.
portcost Specifies the port’s cost. The spanning tree algorithm
uses the cost parameter to decide which port provides
the lowest cost to the root bridge for that LAN. The
range is 0 to 200,000,000. The default setting is Auto-
Detect, which automatically sets port cost according
to the speed of the port. Table 6 lists the port cost with
Auto-Detect.
