Description: Provides extensions to standard Ethernet OAM (802.3ah) management on OneAccess CPE routers.

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 ONEACCESS-ETHOAM-EXT-MIB?

ONEACCESS-ETHOAM-EXT-MIB is a OneAccess proprietary MIB extending IEEE 802.1ag Connectivity Fault Management (Ethernet OAM) with OneAccess-specific detail. Its global enable flag governs the extension, while a MIP (Maintenance Intermediate Point) table records the interface, maintenance-domain (MEG) level, VLAN index, and mode for each configured MIP, alongside a related MEP (Maintenance End Point) table. As a configuration/protocol-status MIB it lets an administrator confirm CFM MIPs/MEPs are correctly provisioned at the intended maintenance-domain level for carrier Ethernet OAM. It is deployed on OneAccess CPE routers providing carrier Ethernet OAM. Engineers can download the ONEACCESS-ETHOAM-EXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ONEACCESS-ETHOAM-EXT-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

  • OneAccess CPE routers (carrier Ethernet OAM)

Monitoring Examples

An administrator checks oacEthOamMipMegLevel for a MIP reporting unexpected CFM behavior, confirming it's configured at the correct maintenance-domain level to interoperate with the carrier's OAM hierarchy.

What Can Be Monitored

  • CFM MIP/MEP configuration (maintenance level, VLAN, mode)

How to Use in IPNetwork Monitor

Example using oacEthOamMepLossNbrOfTxFrames OID:

Select an OneAccess CPE router (carrier Ethernet OAM, 802.1ag CFM extension) 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 oacEthOamMepLossNbrOfTxFrames 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. The number of sent LMM frames. 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 Counter32-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, 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.
