Description: Monitors Carrier-Grade NAT (CGNAT) translation statistics on Benu Networks broadband gateway platforms.

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 BENU-CGNAT-STATS-MIB?

BENU-CGNAT-STATS-MIB is a Benu Networks, Inc. proprietary MIB reporting CGNAT (Carrier-Grade NAT) statistics for the Benu Wireless Access Gateway. Its authentication statistics table, keyed by index, records profile name, public-IP-zero and no-free-port counts, flow add/delete success/failure counts, timer-allocation failures, unsupported-Layer-4-drop count, NAT-flow sync-failure count, and ICMP-ID/TCP-port/UDP-port allocation and release success/failure counts. As a performance MIB it lets an administrator watch CGNAT port/flow allocation failures indicating address-pool exhaustion on a Benu WAG. It is deployed on Benu Networks Wireless Access Gateway platforms. Engineers can download the BENU-CGNAT-STATS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in BENU-CGNAT-STATS-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

  • Benu Networks Wireless Access Gateway platforms

Monitoring Examples

An administrator monitors bCgnatAuthDomainNoFreePortCount to catch CGNAT port-pool exhaustion on a Benu Wireless Access Gateway.

What Can Be Monitored

  • CGNAT flow/port allocation success and failure statistics

How to Use in IPNetwork Monitor

Example using bCgnatAuthDomainPublicIpZeroCount OID:

Select a Benu Networks (Ciena) broadband/WiFi Access Gateway (WAG) platform 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 bCgnatAuthDomainPublicIpZeroCount 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 domain Public IP as zero count. 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, 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.
