Port STP configuration groups
snPortStpPathCost
brcdIp.1.1.3.5.1.1.4
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 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:
•
10 Mbps – 100
•
100 Mbps – 19
•
Gigabit – 4
Valid values: 0 – 65535
NOTE: Over the value of 65535, this MIB stays at the upper value
and the user should access which has a bigger upper range
value.
snPortStpOperState
brcdIp.1.1.3.5.1.1.5
Syntax: Integer Read-only Indicates if the port STP entry is activated and is in running mode:
•
notActivated(0)
•
activated(1)
Default: notActivated(0)
snPortStpPortEnable
brcdIp.1.1.3.5.1.1.6
Syntax: Integer None Indicates whether or not the port is enabled:
•
disabled(0)
•
enabled(1)
snPortStpPortForwardTransi
tions
brcdIp.1.1.3.5.1.1.7
Syntax: Integer32 None Shows the number of times this port has transitioned from the
Learning state to the Forwarding state.
