Chapter 3 Configuring and graphing ports 81Reference for the BayStack 380-24F Gigabit Switch Management SoftwareTable 30 describes the STG tab items.Table 30 STG tab items for a single portItem DescriptionStgId The number of times this port has transitioned from the Learningstate to the Forwarding state.Priority The value of the priority field that is contained in the first(in network byte order) octet of the (2-octet long) Port ID.The other octet of the Port ID is derived from the value ofdot1dStpPort.State The port’s current state as defined by application of theSpanning Tree Protocol. This state controls the action a porttakes when it receives a frame. If the bridge detects a port that ismalfunctioning, it places that port into the broken state. For portsthat are disabled (see EnableStp), this object has a value ofdisabled.EnableStp Allows you to select true or false to enable or disable STP.FastStart Allows you to select true or false to enable or disable FastStart.PathCost The contribution of this port to the cost of paths toward thespanning tree root, which include this port. The IEEE802.1D-1990 standard recommends that the default value of thisparameter be in inverse proportion to the speed of the attachedLAN.DesignatedRoot The unique Bridge Identifier of the bridge recorded as the Rootin the Configuration BPDUs transmitted by the DesignatedBridge for the segment to which the port is attached.DesignatedCost The path cost of the Designated Port of the segment connectedto this port. This value is compared to the Root Path Cost field inreceived bridge PDUs.DesignatedBridge The Bridge Identifier of the bridge that this port considers to bethe Designated Bridge for this port’s segment.DesignatedPort The Port Identifier of the port on the Designated Bridge for thisport’s segment.ForwardTransitions The number of times this port has transitioned from the Learningstate to the Forwarding state.
