Description: Provides textual description and identification objects for Accedian MetroNID device inventory and system information.

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-DESC-MIB?

ACD-DESC-MIB is a vendor-specific MIB from Accedian Networks for their MetroNID line of Ethernet demarcation/network interface devices, used to identify and describe the device and report basic operating health. It exposes inventory/identification data (commercial name, MAC address, identifier, serial number, firmware and hardware version) alongside live operational metrics, most notably CPU usage. It is explicitly useful for monitoring software and hardware status: acdDescCpuUsageCurrent and the 15/30/60/900-second averages let an operator track CPU load trends over time, while the firmware/hardware version and serial number fields support asset and software-version tracking, and acdDescConnectorTable plus acdDescNotifications provide connector-level status and fault traps. It is a relatively self-contained device-identity/health MIB with its own notification (trap) branch rather than relying heavily on other MIBs. It is typically deployed on Accedian MetroNID demarcation devices used by carriers and enterprises to monitor Ethernet service handoff points. Engineers can download the ACD-DESC-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ACD-DESC-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 network interface device

Monitoring Examples

An administrator would poll acdDescCpuUsageCurrent against acdDescCpuUsageAverage60 and acdDescCpuUsageAverage900 to detect a sustained CPU spike versus a brief transient, and check acdDescFirmwareVersion/acdDescHardwareVersion during an inventory audit or after a firmware upgrade to confirm the expected version is running. acdDescConnectorTable would be checked for connector-level status, and acdDescNotifications would fire traps on state changes such as a CPU threshold breach or connector fault. acdDescSerialNumber and acdDescMacBaseAddr are used to positively identify the specific unit in a fleet.

What Can Be Monitored

current CPU usage
15/30/60/900-second average CPU usage
firmware version
hardware version
serial number and MAC address
connector status

How to Use in IPNetwork Monitor

Example using acdDescCpuUsageCurrent 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 acdDescCpuUsageCurrent into the Find box to locate it in the OID tree, then select it and click OK. Indicates the current percentage of CPU usage. 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 Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if utilization exceeds 85%, a common warning threshold before sustained high load affects performance. Click Finish to create the monitor; you can adjust any parameter later.
