Item Description
ID
An identifier used to identify a STG in the device.
BridgeAddress
MAC address used by a bridge when it is referred to in a unique fashion. It is recommended that the number be the smallest MAC address of all ports belonging to the bridge. However, it is only required to be unique. When concatenated with Priority, a unique bridge identifier is formed that is used in the spanning tree protocol.
NumPorts
Number of ports controlled by this bridging entity.
ProtocolSpecification
Version of the spanning tree protocol being run. Values include:
  • decLb100: Indicates the DEC LANbridge 100 spanning tree protocol.
  • ieee8021d: IEEE 802.1d implementations will return this entry. When future versions of the IEEE spanning tree protocol are released that are incompatible with the current version, a new value will be defined.
Priority
Value of the writable portion of the bridge ID. That is, the first two octets of the (8-octet long) bridge ID. The last six octets of the bridge ID are given by the value of BridgeAddress.
BridgeMaxAge
Value that all bridges use for the maximum age of a bridge when it is acting as the root.
Note: 802.1D-1990 specifies that the range is related to the value of BridgeHelloTime. The granularity of this timer is specified by 802.1D-1990 to be 1 second. A badValue error may be returned if the value set is not a whole number.
BridgeHelloTime
Value that all bridges use for HelloTime when a bridge is acting as the root.
Note: The granularity of this timer is specified by 802.1D-1990 to be 1 second. A badValue error may be returned if the value set is not a whole number.
BridgeForwardDelay
Value that all bridges use for ForwardDelay when this bridge is acting as the root.
Note: 802.1D-1990 specifies that the range is related to the value of BridgeHelloTime. The granularity of this timer is specified by 802.1D-1990 to be 1 second. A badValue error may be returned if the value set is not a whole number.
PortMembers
Bit-field used to identify the ports in the system that are members this STG. The bit-field is 32 octets long representing ports 0 to 255 (inclusive).
