Description: HH3C MIB for PPPoE server configuration managing PPPoE session tables and subscriber access on H3C broadband 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 HH3C-PPPOE-SERVER-MIB?

HH3C-PPPOE-SERVER-MIB is a private H3C (Hewlett-Packard/Huawei-3Com joint venture) MIB for the PPPoE server feature on H3C broadband access devices, managing subscriber PPPoE session capacity and authentication. Its data covers session capacity and current usage, authentication statistics (requests, successes, failures), and configurable thresholds for abnormal subscriber offline rates. Its monitoring value is strongly software-service and capacity oriented: comparing current sessions to the maximum shows how close the device is to session-capacity exhaustion and rejecting new subscribers, while a rising ratio of authentication failures to requests flags a problem with subscriber credentials or the backend RADIUS/AAA server; the abnormal-offline thresholds support proactive alerting on subscriber churn anomalies that could indicate a link or software instability. It works alongside standard PPP and RADIUS MIBs for the underlying session and AAA mechanics, functioning as a vendor-specific summarization/threshold layer on top of them. It is deployed on H3C broadband access routers/BRAS equipment in service-provider or enterprise broadband access networks, where operators typically load the HH3C-PPPOE-SERVER-MIB MIB Browser definitions to review these session and threshold objects.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-PPPOE-SERVER-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

H3C broadband access routers / BRAS

Monitoring Examples

An operator compares hh3cPPPoEServerCurrSessions to hh3cPPPoEServerMaxSessions to catch a device nearing subscriber session capacity before new customers are rejected, and watches hh3cPPPoEServerAuthFailures against hh3cPPPoEServerAuthRequests/hh3cPPPoEServerAuthSuccesses to detect an authentication backend outage. Thresholds such as hh3cPPPoESAbnormOffsThreshold and hh3cPPPoESAbnormOffPerThreshold would trigger an alert if the percentage of abnormal subscriber disconnects spikes, indicating a link, hardware, or software instability affecting PPPoE sessions.

What Can Be Monitored

current vs maximum PPPoE sessions
authentication request/success/failure counts
abnormal offline threshold and percentage
normal offline percentage threshold

How to Use in IPNetwork Monitor

Example using hh3cPPPoEServerAuthRequests OID:

Select an H3C broadband access router/BRA (PPPoE server) 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 hh3cPPPoEServerAuthRequests into the Find box to locate it in the OID tree, then select it and click OK. The number of authentication requests. 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.
