Description: NETGEAR-CAPTIVE-PORTAL-MIB module

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 NETGEAR-CAPTIVE-PORTAL-MIB?

This is a Netgear-proprietary MIB that manages the Captive Portal feature on Netgear network devices, the mechanism that redirects unauthenticated wireless or wired clients to a login/acceptance web page before granting network access. As no sample objects were captured for this module, and given the terse module description ("The NETGEAR Private MIB for Captive Portal"), it can only be characterized generally as covering captive-portal configuration (e.g., enable/disable, portal group assignment, and possibly session/client status) rather than confirmed against concrete object names. Its role in device monitoring would typically be confirming whether the captive portal feature is enabled/active and tracking authenticated client sessions passing through it, functioning as a software-feature/service status indicator on the device. It likely depends on underlying interface/VLAN MIBs to associate captive portal instances with specific network segments. Typical deployment context is a Netgear wireless access point, router, or managed switch used to provide guest or public Wi-Fi access requiring a web-based login/acceptance step. Network engineers evaluating or troubleshooting this functionality can download the NETGEAR-CAPTIVE-PORTAL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NETGEAR-CAPTIVE-PORTAL-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

  • Netgear wireless access points/routers
  • Netgear managed switches

Monitoring Examples

No sample objects were provided for this MIB, so a concrete monitoring scenario referencing real object names cannot be given honestly; based on the module description alone, this MIB would be expected to expose captive-portal enable/disable state and possibly per-portal or per-client session status, but the specific table/object names are not confirmed here.

How to Use in IPNetwork Monitor

Example using cpCaptivePortalClientBytesReceived OID:

Select a Netgear wireless access point/router or managed switch (Captive Portal) 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 cpCaptivePortalClientBytesReceived 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 number of bytes received by this client. 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.
