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. Port numbers
must be specified in the following format:
module ID.port number
For instructions, refer to “Port Numbers in Commands”
on page 42.
pathcost or 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 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 11 lists the STP port costs with Auto-Detect.
Table 12 lists the STP port costs with Auto-Detect when
a port is part of a port trunk.
