CISCOSB-WBA-MIB

Description: Manages web-based authentication (WBA) portal settings and client sessions on Cisco Small Business switches.

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.

CISCOSB-WBA-MIB is a Cisco Small Business private MIB for Web-Based Authentication (WBA), a captive-portal style mechanism that requires clients to authenticate via a web login page before gaining network access. It exposes an auxiliary table tracking each client's IP address, authentication status, failure reason, retry flag, and the username/password used during the login attempt. Its monitoring value is authentication/session status—identifying clients currently pending or failing web authentication and diagnosing why (via the failure reason code), which is a fault/access-control monitoring function rather than a performance metric. It complements 802.1X-based access control (CISCOSB-DOT1X-MIB) as an alternative authentication method and has no strong external MIB dependency. It is deployed on Cisco Small Business switches providing guest or BYOD network access via a browser-based login portal. Engineers can download the CISCOSB-WBA-MIB file directly to load it into their MIB browser.

An administrator would poll rlWBAAuxiliaryTable/rlWBAAuxiliaryEntry, checking rlWBAStatus for each client identified by rlWBAIp to see if authentication succeeded, and rlAuxFailReason to diagnose why a login attempt failed (e.g. bad credentials). A high rate of entries with rlIsRetryFlag set and a consistent rlAuxFailReason would indicate a systemic issue such as an expired shared credential or portal misconfiguration rather than isolated user error.
