Description: H3C MIB for PPPoE server management tracking active PPPoE sessions, subscriber accounts, and bandwidth usage.

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 H3C-PPPOE-SERVER-MIB?

H3C-PPPOE-SERVER-MIB is an H3C-specific MIB for managing and monitoring the PPPoE (PPP over Ethernet) server feature on H3C broadband access devices, which terminates subscriber PPPoE sessions for internet access. It exposes session-capacity and current-session-count scalars along with authentication counters (requests, successes, failures) and threshold objects for abnormal or normal session-offline percentages/rates. As a service-health monitoring MIB it lets operators watch active subscriber session load against capacity, detect authentication problems (a rising h3cPPPoEServerAuthFailures count relative to h3cPPPoEServerAuthRequests suggests a credential or RADIUS backend issue), and flag mass session drop-offs via the abnormal-offline threshold objects, a strong signal of a server-side fault or upstream authentication outage. It has no explicit stated MIB dependency but works alongside RADIUS/AAA configuration elsewhere on the device for subscriber authentication. It is typically deployed on H3C broadband remote access servers (BRAS) or edge routers providing PPPoE-based subscriber access in ISP/carrier networks. Engineers can download the H3C-PPPOE-SERVER-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-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 remote access servers (BRAS)
H3C edge routers with PPPoE server role

Monitoring Examples

Comparing h3cPPPoEServerCurrSessions against h3cPPPoEServerMaxSessions shows how close the server is to its subscriber-session capacity. Watching h3cPPPoEServerAuthFailures relative to h3cPPPoEServerAuthRequests and h3cPPPoEServerAuthSuccesses reveals authentication problems, such as a RADIUS server outage causing failures to spike. If h3cPPPoESAbnormOffsThreshold or h3cPPPoESAbnormOffPerThreshold is exceeded, it indicates an unusually large or fast wave of subscriber sessions dropping, often pointing to an upstream network or server fault.

What Can Be Monitored

current vs. maximum PPPoE sessions
authentication request/success/failure counts
abnormal session offline thresholds
normal session offline rate threshold

How to Use in IPNetwork Monitor

Example using h3cPPPoEServerAuthRequests OID:

Select an H3C broadband remote access server (BRAS)/edge router (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 h3cPPPoEServerAuthRequests 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.
