Description: Ubiquiti EdgeSwitch captive portal MIB for configuring and monitoring web-based network access control for guest users.

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 EdgeSwitch-CAPTIVE-PORTAL-MIB?

EdgeSwitch-CAPTIVE-PORTAL-MIB is a Ubiquiti Networks private MIB for the EdgeSwitch line, providing configuration and monitoring objects for the switch's captive-portal feature, which redirects guest users to a web-based authentication page before granting network access. It exposes configuration data such as portal definitions, authentication settings, and associated interfaces, along with status information about active captive-portal sessions. Its monitoring relevance is software/service oriented: an administrator can check whether the captive portal service is enabled and functioning and track client authentication/session status, rather than physical hardware sensors. It is a Ubiquiti-specific private MIB rather than one built on an external IETF captive-portal standard, deployed alongside other EdgeSwitch private MIBs on the same platform. It is typically used in guest Wi-Fi/wired access deployments such as hotels, offices, or campuses using Ubiquiti EdgeSwitch hardware. Engineers can download the EdgeSwitch-CAPTIVE-PORTAL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EdgeSwitch-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

  • Ubiquiti EdgeSwitch managed Ethernet switch

Monitoring Examples

No specific object/table names were provided in the source extract for this MIB, so specific objects cannot be cited without invention. In general use, an administrator would check captive-portal enablement and session-count style objects to confirm the guest-access web-redirect feature is active and to see how many guest clients are currently in an authenticated or pending state.

What Can Be Monitored

  • captive portal enable/status
  • guest session count
  • authentication policy configuration

How to Use in IPNetwork Monitor

Example using cpCaptivePortalClientBytesReceived OID:

Select an Ubiquiti EdgeSwitch managed Ethernet 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.
