Description: Manages IEEE 802.1ag Connectivity Fault Management (CFM) configuration and statistics on Accedian MetroNID devices.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ACD-CFM-MIB?

ACD-CFM-MIB is an Accedian Networks proprietary MIB module that extends IEEE 802.1ag Ethernet Connectivity Fault Management (CFM) functionality on Accedian MetroNID carrier Ethernet demarcation devices. It exposes configuration and results data for delay-measurement (DM) sessions and packet-loss measurement between maintenance endpoints (MEPs), including measurement intervals, reference periods, and one-way delay thresholds. The module is focused on monitoring network performance and service-level health rather than internal device hardware, letting operators track round-trip and one-way delay and packet loss across a carrier Ethernet path to detect service degradation. It explicitly complements the standard IEEE P802.1ag CFM MIB, relying on that standard's MEP/MEG object model for endpoint identification. It is typically deployed on carrier-grade Ethernet demarcation ("NID") devices at customer or network edge sites, making ACD-CFM-MIB SNMP monitoring a standard part of SLA verification and troubleshooting for Carrier Ethernet services.

IPNetwork Monitor allows you to monitor SNMP objects defined in ACD-CFM-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.

Supported Devices

  • Accedian MetroNID Carrier Ethernet demarcation device

Monitoring Examples

An operator would poll acdCfmDmCfgTable/acdCfmDmCfgEntry entries indexed by acdCfmDmCfgID to see delay-measurement sessions configured between a local acdCfmDmCfgMepIdx and a remote acdCfmDmCfgRemoteMepId, checking acdCfmDmCfgEnable and acdCfmDmCfgInterval to confirm a session is active and its polling cadence. Rising values against the acdCfmDmCfgOneWayDelayMax threshold, combined with acdCfmDmCfgOneWayDelayEnable, would signal that one-way latency between MEPs has exceeded SLA limits. acdCfmDmCfgRowStatus would be checked when provisioning or removing a monitoring session via SNMP SET. Traps under acdCfmNotifications would alert operators in real time when thresholds are breached.

What Can Be Monitored

  • one-way and round-trip delay measurement sessions
  • packet loss configuration and results
  • delay measurement interval and reference period
  • remote MEP delay measurement peers
  • delay threshold breach status
