SET STP PORT
Syntax
set stp port=port
[pathcost|portcost=auto|portcost]
[portpriority=portpriority]
Parameters
port Specifies the port you want to configure. You can
configure more than one port at a time. You can
specify the ports individually (for example, 5, 7, 22), as
a range (for example, 18-23), or both (for example, 1, 5,
14-22).
pathcost Specifies the port’s cost. The parameters are
portcost equivalent. The spanning tree algorithm uses the cost
parameter to decide which port provides the lowest
cost to the root bridge for that LAN. This parameter
can take the range of 1 (Automatic Update) to 65,535,
or AUTO. The default setting is AUTO, for Automatic
Update, which automatically sets port cost according
to the speed of the port. Table 5 lists the STP port costs
with Auto-Detect.
Table 6 lists the STP port costs with Auto-Detect when
a port is part of a port trunk.
