Current source routing protocols limit this value to the range: 0 through 4095. (The value 0 is used by some management applications for special test cases.)

A value of 65535 signifies that no target segment is assigned to this port." ::= { dot1dSrPortEntry 5 } -- It would be nice if we could use ifMtu as the size of the -- largest frame, but we can't because ifMtu is defined to be -- the size that the (inter-)network layer can use which can -- differ from the MAC layer (especially if several layers of -- encapsulation are used). dot1dSrPortLargestFrame OBJECT-TYPE SYNTAX INTEGER ACCESS read-write STATUS mandatory DESCRIPTION "The maximum size of the INFO field (LLC and above) that this port can send/receive. It does not include any MAC level (framing) octets. The value of this object is used by this bridge to determine whether a modification of the LargestFrame (LF, see [14]) field of the Routing Control field of the Routing Information Field is necessary. 64 valid values are defined by the IEEE 802.5M SRT Addendum: 516, 635, 754, 873, 993, 1112, 1231, 1350, 1470, 1542, 1615, 1688, 1761, 1833, 1906, 1979, 2052, 2345, 2638, 2932, 3225, 3518, 3812, 4105, 4399, 4865, 5331, 5798, 6264, 6730, 7197, 7663, 8130, 8539, 8949, 9358, 9768, 10178, 10587, 10997, 11407, 12199, 12992, 13785, 14578, 15370, 16163, 16956, 17749, 20730, 23711, 26693, 29674, 32655, 35637, 38618, 41600, 44591, 47583, 50575, 53567, 56559, 59551, and 65535. An illegal value will not be accepted by the bridge." ::= { dot1dSrPortEntry 6 } dot1dSrPortSTESpanMode OBJECT-TYPE SYNTAX INTEGER { auto-span(1), disabled(2), forced(3) } ACCESS read-write STATUS mandatory DESCRIPTION "Determines how this port behaves when presented with a Spanning Tree Explorer frame. The value 'disabled(2)' indicates that the port will not accept or send Spanning Tree Explorer packets; any STE packets received will be silently discarded. The value 'forced(3)' indicates the port will always accept and propagate Spanning Tree Explorer frames. This allows a manually configured Spanning Tree for this class of packet to be configured. Note that unlike transparent bridging, this is not catastrophic to the network if there are loops. The value 'auto-span(1)' can only be returned by a bridge that both implements the Spanning Tree Protocol and has use of the protocol enabled on this port. The behavior of the port for Spanning Tree Explorer frames is determined by the state of dot1dStpPortState. If the port is in the 'forwarding' state, the frame will be accepted or propagated. Otherwise, it will be silently discarded." ::= { dot1dSrPortEntry 7 } dot1dSrPortSpecInFrames OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory DESCRIPTION "The number of Specifically Routed frames, also referred to as Source Routed Frames, that have been received from this port's segment." ::= { dot1dSrPortEntry 8 } dot1dSrPortSpecOutFrames OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory DESCRIPTION "The number of Specifically Routed frames, also referred to as Source Routed Frames, that this port has transmitted on its segment." ::= { dot1dSrPortEntry 9 } dot1dSrPortApeInFrames OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory DESCRIPTION "The number of All Paths Explorer frames, also referred to as All Routes Explorer frames, that have been received by this port from its segment." ::= { dot1dSrPortEntry 10 } dot1dSrPortApeOutFrames OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory DESCRIPTION "The number of all Paths Explorer Frames, also referred to as All Routes Explorer frames, that have been transmitted by this port on its segment." ::= { dot1dSrPortEntry 11 } dot1dSrPortSteInFrames OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory DESCRIPTION "The number of spanning tree explorer frames that have been received by this port from its segment." ::= { dot1dSrPortEntry 12 } dot1dSrPortSteOutFrames OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory DESCRIPTION "The number of spanning tree explorer frames that have been transmitted by this port on its segment." ::= { dot1dSrPortEntry 13 } dot1dSrPortSegmentMismatchDiscards OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory DESCRIPTION "The number of explorer frames that have been discarded by this port because the routing descriptor field contained an invalid adjacent segment value." ::= { dot1dSrPortEntry 14 } dot1dSrPortDuplicateSegmentDiscards OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory DESCRIPTION "The number of frames that have been discarded by this port because the routing descriptor field contained a duplicate segment identifier." ::= { dot1dSrPortEntry 15 } dot1dSrPortHopCountExceededDiscards OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory DESCRIPTION "The number of explorer frames that have been discarded by this port because the Routing Information Field has exceeded the maximum route descriptor length." ::= { dot1dSrPortEntry 16 } dot1dSrPortDupLanIdOrTreeErrors OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory DESCRIPTION "The number of duplicate LAN IDs or Tree errors.

This error can occur in implementations which do only a LAN-in ID and Bridge Number check instead of a LAN-in ID, Bridge Number, and LAN-out ID check before they forward broadcast frames." ::= { dot1dSrPortEntry 18 } -- scalar object in dot1dSr dot1dSrBridgeLfMode OBJECT-TYPE SYNTAX INTEGER { mode3(1), mode6(2) } ACCESS read-write STATUS mandatory DESCRIPTION "Indicates whether the bridge operates using older 3 bit length negotiation fields or the newer 6 bit length field in its RIF." ::= { dot1dSr 2 } -- The Port-Pair Database -- Implementation of this group is optional. -- This group is implemented by those bridges that support -- the direct multiport model of the source route bridging -- mode as defined in the IEEE 802.5 SRT Addendum to -- 802.1d. -- Bridges implementing this group may report 65535 for -- dot1dSrPortBridgeNumber and dot1dSrPortTargetSegment, -- indicating that those objects are not applicable. dot1dPortPairTableSize OBJECT-TYPE SYNTAX Gauge ACCESS read-only STATUS mandatory DESCRIPTION "The total number of entries in the Bridge Port Pair Database." ::= { dot1dPortPair 1 } -- the Bridge Port-Pair table -- this table represents port pairs within a bridge forming -- a unique bridge path, as defined in the IEEE 802.5M SRT -- Addendum. dot1dPortPairTable OBJECT-TYPE SYNTAX SEQUENCE OF Dot1dPortPairEntry ACCESS not-accessible STATUS mandatory DESCRIPTION "A table that contains information about every port pair database entity associated with this source routing bridge." ::= { dot1dPortPair 2 } dot1dPortPairEntry OBJECT-TYPE SYNTAX Dot1dPortPairEntry ACCESS not-accessible STATUS mandatory DESCRIPTION "A list of information for each port pair entity of a bridge."

The purpose of bridge number is to disambiguate between multiple paths connecting the same two LANs." ::= { dot1dPortPairEntry 3 } dot1dPortPairBridgeState OBJECT-TYPE SYNTAX INTEGER { enabled(1), disabled(2), invalid(3) } ACCESS read-write STATUS mandatory DESCRIPTION "The state of dot1dPortPairBridgeNum.
