What Is RC-MLT-MIB?

RC-MLT-MIB is a Bay Networks/Nortel Accelar enterprise MIB for managing Multi-Link Trunking (MLT), Nortel's link-aggregation technology, on Rapid-City series switches. It exposes per-MLT-group extended interface statistics, unicast, multicast, and broadcast packet counters plus high-capacity octet/packet counters, alongside multicast traffic distribution and notification configuration objects. This supports traffic/performance monitoring of aggregated links: an administrator can see whether traffic is balanced across member ports and detect abnormal packet-type distributions that might indicate a failing link or loop. It extends standard IF-MIB-style high-capacity counters with MLT-group-specific extensions in the vendor's Rapid-City tree. It is deployed on Bay Networks/Nortel Accelar/Rapid-City switches wherever multiple physical links are trunked together for bandwidth and redundancy, and the RC-MLT-MIB MIB is what NMS platforms poll to track that trunked-link performance.

IPNetwork Monitor allows you to monitor SNMP objects defined in RC-MLT-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

What Can Be Monitored

  • MLT unicast/multicast/broadcast packet counts
  • high-capacity in/out octets per trunk
  • multicast traffic distribution
  • trunk state-change notifications

Supported Devices

  • Bay Networks/Nortel Accelar (Rapid-City) routing switch

Monitoring Examples

An operator polls rcStatMltIfExtnTable/rcStatMltIfExtnEntry keyed by rcStatMltIfExtnMltId to compare rcStatMltIfExtnIfHCInOctets/rcStatMltIfExtnIfHCOutOctets against rcStatMltIfExtnIfInBroadcastPkts/rcStatMltIfExtnIfOutBroadcastPkts, watching for broadcast storms on a trunked group. rcMltMcastDistribution is checked to confirm multicast traffic is being load-shared as expected across MLT member links, and rcMltNotificationObjects govern which trunk state-change traps (e.g., member port up/down) are sent to the NMS.

Five hundred and twelve bit-times corresponds to 51.2 microseconds on a 10 mb/s system. A (late) collision included in a count represented by an instance of this object is also considered as a (generic) collision for purposes of other collision-related statistics.
C32 rcStatMltEtherExcessiveCollis1.3.6.1.4.1.2272.1.12.6.2.1.9Counter32read-onlyA count of frames for which transmission on a particular MLT fails due to excessive collisions.

A frame is only counted by an instance of this object if it is not counted by the corresponding instance of either the LateCollisions object, the ExcessiveCollisions object, or the CarrierSenseError object.
C32 rcStatMltEtherCarrierSenseError1.3.6.1.4.1.2272.1.12.6.2.1.11Counter32read-onlyThe number of times that the carrier sense condition was lost or never asserted when attempting to transmit a frame on a particular MLT.

The count represented by an instance os this object is incremented when the frame TooLong status is returned by the MAC service to the LLC (or other MAC user).

C32 rcStatMltEtherIMacReceiveError1.3.6.1.4.1.2272.1.12.6.2.1.13Counter32read-onlyA count of frames for which reception on a particular MLT fails due to an internal MAC sublayer receive error. A frame is only counted by an instance of this object if it is not counted by the corresponding instance of either the FrameTooLongs object, the AlignmentErrors object, of the FCSErrors objects. The precise meaning of the count represented by an instance of this object is implementation specific. In particular, an instance of this object may represent a count of receive errors on a particular interface that are not otherwise counted.
