Port STP configuration groups
snIfStpPathCost
brcdIp.1.1.3.5.2.1.4
Syntax: Integer Read-write Shows the value of the dot1dStpPortPathCost, which is the port’s path
cost to reach the root bridge. When selecting among multiple links to
the root bridge, STP or RSTP chooses the link with the lowest path cost
and blocks the other paths.
IEEE 802.1D-1990 recommends that the default value of this
parameter be in inverse proportion to the speed of the attached LAN.
Writing a value of zero to this object sets the path cost to a default
value which automatically changes according to port speed.
Reading a value of zero indicates an unknown path cost because the
port speed cannot be determined due to the speed auto sense that is
currently in progress.
Each port type has its own default STP path cost.
