Description: Manages traffic shaping profiles and egress queuing parameters on Accedian MetroNID Ethernet performance 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-SHAPER-MIB?

ACD-SHAPER-MIB manages traffic shaping and egress queuing on Accedian MetroNID carrier Ethernet performance/demarcation devices, an area of Carrier Ethernet service assurance. It exposes per-code-point (CoS/color/PCP-based) statistics such as forwarded and delayed octet/packet counts and rates, in addition to shaper configuration. Monitoring with this MIB centers on performance data: tracking forwarded vs. delayed traffic per class of service reveals whether the shaper is enforcing bandwidth profiles correctly or whether a class is being excessively delayed, which is a software/configuration health indicator for the shaping function rather than a hardware sensor reading. It is closely tied to MEF (Metro Ethernet Forum) traffic-management concepts (color marking, CoS/PCP), reflecting its carrier-Ethernet lineage. It is deployed on Accedian MetroNID network interface devices used for Ethernet service demarcation and SLA assurance at customer or carrier handoff points. Network engineers evaluating or troubleshooting this functionality can download the ACD-SHAPER-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ACD-SHAPER-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 administrator would poll acdShaper1CodePointStatsTable, keyed by acdShaper1CodePointStatsDstID/SrcID/ColorID/PcpID, to read acdShaper1CodePointStatsFwdOctets, acdShaper1CodePointStatsFwdPkts, and acdShaper1CodePointStatsFwdRate alongside the delayed-traffic counters acdShaper1CodePointStatsDelayedOctets/DelayedPkts/DelayedRate. A sustained rise in the delayed counters relative to forwarded counters for a given color/PCP entry indicates that class of traffic is exceeding its shaped rate and is being held back, which would show up to the customer as added latency or jitter for that CoS.

What Can Be Monitored

forwarded octets/packets per class of service
forward rate per CoS
delayed octets/packets per class of service
delay rate per CoS/color/PCP

How to Use in IPNetwork Monitor

Example using acdShaper1CodePointStatsFwdOctets OID:

Select an Accedian MetroNID device as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type acdShaper1CodePointStatsFwdOctets into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the total number of octets forwarded without delay. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline (in Octets), since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
