What Is CADANT-CMTS-LAYER2CMTS-MIB?

CADANT-CMTS-LAYER2CMTS-MIB is an ARRIS/Cadant enterprise MIB for cable network equipment that manages Layer 2 CMTS (L2CM) bridging features on Cadant Cable Modem Termination System platforms. It exposes bridge-group and bridge-port configuration, the policy for assigning ISP subnet addresses per bridge group, and per-bridge-group spanning tree support, effectively modeling how cable modem traffic is segmented and bridged upstream. Its monitoring value centers on configuration/operational status rather than hardware sensors: bridge group row status (active/creating/destroying), bridge group naming, MAC address assignment, and per-bridge-group traffic statistics reveal whether Layer 2 segmentation for a given ISP or service group is correctly provisioned and passing traffic. It builds on and complements DOCSIS/CMTS-specific MIBs and standard BRIDGE-MIB/dot3ad conventions referenced for spanning tree and link aggregation, and MSO engineers configuring a new bridge group frequently open a CADANT-CMTS-LAYER2CMTS-MIB MIB Browser session to check the cadBridgeGroupTable column definitions beforehand. It is deployed by cable MSOs managing Cadant/ARRIS CMTS chassis providing broadband cable modem service.

IPNetwork Monitor allows you to monitor SNMP objects defined in CADANT-CMTS-LAYER2CMTS-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

  • bridge group configuration status
  • bridge group name
  • bridge port assignment
  • bridge group MAC address
  • spanning tree participation
  • bridge group traffic statistics

Supported Devices

  • ARRIS/Cadant Cable Modem Termination System (CMTS)

Monitoring Examples

An operator would poll cadBridgeGroupTable/cadBridgeGroupEntry, keyed by cadBgIndex, to check cadBgName and cadBgRowStatus for each configured bridge group, confirming a group is active rather than stuck in a notInService state. cadBridgeGroupStatsTable/cadBridgeGroupStatsEntry provides per-bridge-group statistics such as cadBgLeaderBgpId and cadBgMacAddress useful for verifying bridging topology, while cadBridgePortTable shows which physical/logical ports belong to each bridge group. A bridge group with an unexpected row status or missing ports would indicate a misconfigured cable modem termination segment.

cadLayer2Mib1.3.6.1.4.1.4998.1.1.20.1This MIB module contains the following information: 1) The concept of bridge groups and bridge ports 2) The policy governed the assigment of Internet Service Provider's subnet addresses per bridge group 3) Support for per bridge group spanning tree

cadBridgeGroupTable1.3.6.1.4.1.4998.1.1.20.1.1.2not-accessibleA table (and along with other supported tables) contains bridge group information. A bridge group is actually a Port-Vlan concept which consists of one or more E-ports and one or more D-ports. Each D-port includes its associated U-ports and is further subdivided into 3 sub-ports associated with different types of traffic. The CM sub-port carries traffic for the cable-modem itself. The CPEAUTH sub-port carries traffic for an authorized CPE behind a cable-modem. The CPEUNAUTH sub-port carries traffic for an unauthorized CPE behind a cable-modem. Initially, all ports belong to the OAM&P bridge group when a card is first provisioned. Bridge ports can only exist in one bridge group at a time and can be moved between them. Generally, the CPEAUTH sub-port on the D card would be in a bridge group with an E port that had access to the internet and the DHCP servers for the ISP used by the subscriber. The CM sub-port would be in a bridge group with an E port that had access to the DHCP servers and administrative controls for the MSO. The CPEUNAUTH sub-port would be in a bridge group that included access to a sign-on server.
