NameData TypeValue
BridgeForwardDelayuint32
DescriptionstringThe ForwardDelay parameter to be used by all switches in the network if this switch becomes the root.
MappingStringsstringMIB.IETF|BRIDGE-MIB.dot1dStpBridgeForwardDelay
PUnitstringsecond * 10^-2
UnitsstringHundredths of Seconds
BridgeHelloTimeuint32
DescriptionstringThe HelloTime parameter to be used by all switches in the network if this switch becomes the root.
MappingStringsstringMIB.IETF|BRIDGE-MIB.dot1dStpBridgeHelloTime
PUnitstringsecond * 10^-2
UnitsstringHundredths of Seconds
BridgeMaxAgeuint32
DescriptionstringThe MaxAge parameter to be used by all switches in the network if this switch becomes the root.
MappingStringsstringMIB.IETF|BRIDGE-MIB.dot1dStpBridgeMaxAge
PUnitstringsecond * 10^-2
UnitsstringHundredths of Seconds
DesignatedRootstring
DescriptionstringThe complete Bridge ID (Priority + MAC Address) of the root bridge. The format of the priority bits are the first two octets of the 8-octet long Bridge ID. Note that the MAC address is formatted as twelve hexadecimal digits (e.g., "010203040506"), with each pair representing one of the six octets of the MAC address in "canonical" bit order according to RFC 2469.

ForwardDelayuint32
DescriptionstringThe time spent by a port in the listening state before transitioning to the learning state, and in the learning state before transitioning to the forwarding state, as learned from the network. This value is also used during the period of a topology change as the maximum age of Spanning Tree information before discard.
MappingStringsstringMIB.IETF|BRIDGE-MIB.dot1dStpForwardDelay
PUnitstringsecond * 10^-2
UnitsstringHundredths of Seconds
HelloTimeuint32
DescriptionstringThe current value of the interval between transmission of bridge PDUs by the switch, on any port for which it is the spanning tree root or trying to become so, as learned from the network.
MappingStringsstringMIB.IETF|BRIDGE-MIB.dot1dStpHelloTime
PUnitstringsecond * 10^-2
UnitsstringHundredths of Seconds
HoldTimeuint32
DescriptionstringThe minimum interval between transmission of bridge PDUs through a given port, as learned from the network.
MappingStringsstringMIB.IETF|BRIDGE-MIB.dot1dStpHoldTime
PUnitstringsecond * 10^-2
UnitsstringHundredths of Seconds
MaxAgeuint32
DescriptionstringThe current value for the maximum age of Spanning Tree information before discard, as learned from the network.
MappingStringsstringMIB.IETF|BRIDGE-MIB.dot1dStpMaxAge
PUnitstringsecond * 10^-2
UnitsstringHundredths of Seconds
Priorityuint16
DescriptionstringThe format of the priority bits are the first two octets of the 8-octet long Bridge ID. The other (last) 6 octets of the Bridge ID are given by the value of the Bridge Address. A priority that can be assigned to the switch for use in constructing the spanning tree. The unique identifier for a switch is constructed by concatenating the MAC address associated with the switch for spanning tree operations to the two-byte priority. Choice of the priority value influences election of the root bridge.
MappingStringsstringMIB.IETF|BRIDGE-MIB.dot1dStpPriority
ProtocolSpecuint16
DescriptionstringThe version of the spanning tree protocol used by the switch.
MappingStringsstringMIB.IETF|BRIDGE-MIB.dot1dStpProtocolSpecification
ValueMapstring1, 2, 3
ValuesstringUnknown, DEC LB100, IEEE 802d
RootCostuint16
DescriptionstringThe cost of the path from the switch to the root.
MappingStringsstringMIB.IETF|BRIDGE-MIB.dot1dStpRootCost
RootPortuint16
DescriptionstringThe port number of the port having the lowest cost path to the root bridge.
MappingStringsstringMIB.IETF|BRIDGE-MIB.dot1dStpRootPort
SpanningTreeBridgeAddressstring
DescriptionstringMAC address used by the spanning tree service when it must be uniquely identified. When concatenated with a SpanningTreeService Priority, a unique bridge identifier results. This property is defined for use of switches supporting multiple spanning tree services. Note that the MAC address is formatted as twelve hexadecimal digits (e.g., "010203040506"), with each pair representing one of the six octets of the MAC address in "canonical" bit order according to RFC 2469.
