Source Route GroupFast Network 10 MIB Reference GuidePage 4-9dot1dSrPortLocalSegment {dot1dSrPortEntry 3}Integer Read-WriteThe segment number that uniquely identifies the segment to which this port isconnected. Current source routing protocols limit this value to the range 0through 4095. A value of 65535 signifies that no segment number is assigned tothis port.dot1dSrPortBridgeNum {dot1dSrPortEntry 4}Integer Read-WriteA bridge number uniquely identifies a bridge when more than one bridge is usedto span the same two segments. Current source routing protocols limit this valueto the range 0 through 15. A value of 65535 signifies that no bridge number isassigned to this bridge.dot1dSrPortTargetSegment {dot1dSrPortEntry 5}Integer Read-WriteThe segment number that corresponds to the target segment this port isconsidered to be connected to by the bridge. Current source routing protocolslimit this value to the range 0 through 4095. A value of 65535 signifies that notarget segment is assigned to this port.dot1dSrPortLargestFrame {dot1dSrPortEntry 6}Integer Read-WriteThe 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 thisobject is used by this bridge to determine whether a modification of theLargestFrame field of the Routing Control field of the Routing Information Fieldis necessary. Valid values as defined by the 802.5 source routing bridgingspecification are 516, 1500, 2052, 4472, 8144, 11407, 17800, and 65535 octets.Behavior of the port when an illegal value is written is implementation specific. Itis recommended that a reasonable legal value be chosen.
