Description: Manages Mobile IP home and foreign agent configuration and mobility binding statistics on Cisco routers.

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 CISCO-MOBILE-IP-MIB?

CISCO-MOBILE-IP-MIB is a Cisco extension of the IETF Mobile IP MIB (RFC 2006) for routers acting as Mobile IP Home Agents (HA) and Foreign Agents (FA). It exposes data about mobile node registrations, visitor lists, and mobility bindings - i.e. which mobile nodes are currently registered as visitors with a given FA, their home addresses and home agent addresses, and registration lifetimes. Administrators use this MIB primarily for monitoring the operational status of Mobile IP services on the router - tracking active visitor counts, registration time remaining, and registration flags to detect stale bindings, registration churn, or capacity/scaling issues on the mobility service. It builds directly on the standard Mobile IP MIB structure defined in RFC 2006, extending it with Cisco-specific FA/HA visitor-registration objects. It is deployed on Cisco routers providing Mobile IP mobility services in service-provider or enterprise mobile-access networks. Engineers can download the CISCO-MOBILE-IP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-MOBILE-IP-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

  • Cisco router acting as Mobile IP Home Agent/Foreign Agent

Monitoring Examples

An admin polling cmiFaRegVisitorTable (via cmiFaRegVisitorEntry) can see how many mobile nodes are currently registered as visitors on a foreign agent, using cmiFaRegVisitorHomeAddress and cmiFaRegVisitorHomeAgentAddress to correlate each visitor back to its home network. The counter cmiFaRegTotalVisitors gives a running total useful for capacity trending under cmiFa, while cmiFaRegVisitorTimeRemaining flags registrations nearing expiration - a sudden drop in remaining time across many entries could indicate a re-registration storm or HA reachability problem. cmiFaRegVisitorRegFlags exposes registration flags (e.g. simultaneous bindings) useful for diagnosing binding anomalies, and cmiFaRegVisitorRegIDLow/High let an admin match a specific registration request to its response.

What Can Be Monitored

  • total registered visitors
  • visitor home address bindings
  • registration time remaining
  • registration flags
  • home agent address mapping

How to Use in IPNetwork Monitor

Example using cmiFaInitRegRequestsReceived OID:

Select a Cisco router acting as Mobile IP Home Agent/Foreign Agent 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 cmiFaInitRegRequestsReceived into the Find box to locate it in the OID tree, then select it and click OK. It reports the total number of initial Registration Requests received by the foreign agent. 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.
