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-MODEM-MGMT-MIB?
CISCO-MODEM-MGMT-MIB manages analog modem pools, call statistics, and line quality on Cisco access server (dial-up) platforms. It exposes system-wide modem inventory and status counters as well as per-group modem configuration, covering how many modems are installed, in use, available, unavailable, or dead. Its monitoring value is squarely hardware/resource status: tracking modem availability and failure counts (cmSystemModemsInUse, cmSystemModemsAvailable, cmSystemModemsUnavailable, cmSystemModemsDead) lets an operator detect capacity exhaustion or failing modem hardware in real time, alongside watchdog and poll timers that govern health-check behavior. It is a Cisco-proprietary MIB with no strong dependency on other standard MIBs beyond general SNMP framework conventions. It is deployed on legacy Cisco access servers (e.g., AS5x00 series) providing dial-in modem pooling for remote access services. Engineers can download the CISCO-MODEM-MGMT-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-MODEM-MGMT-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 access server (dial-up/modem pool platform, e.g. AS5x00 series)
Monitoring Examples
An operator would poll cmSystemModemsInUse against cmSystemModemsAvailable to determine modem pool utilization and detect capacity exhaustion during peak dial-in hours. A rising cmSystemModemsDead or cmSystemModemsUnavailable count would reveal failing modem hardware needing replacement. cmGroupTable entries let an admin break this down per configured modem group, while cmSystemWatchdogTime and cmSystemStatusPollTime show how frequently the agent refreshes this modem health data.
What Can Be Monitored
- modems in use count
- modems available count
- modems unavailable/dead count
- modem group configuration
- status poll interval
- watchdog timer

How to Use in IPNetwork Monitor
Example using cmNoCarriers OID:
Select a Cisco access server (dial-up/modem pool, e.g. AS5x00, legacy) 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 cmNoCarriers into the Find box to locate it in the OID tree, then select it and click OK. It reports a counter that indicates the number of times that the disconnect reason is no carrier. 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 (in calls), 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.

This object is valid only for modems which have cmManageable to be true. |
| T/F cmATModePermit | 1.3.6.1.4.1.9.9.47.1.3.2.1.1 | TruthValue | read-write | Direct Connect session is used for test and debugging purpose by using the modem AT commands through the out of band management port when cmManageable is true. This object specifies whether the Direct Connect session is permitted to be used at this modem. If cmManageable is true(1), Direct Connect session via the out of band port is allowed and false(2) indicates that it isn't allowed for the modem. |
| T/F cmBad | 1.3.6.1.4.1.9.9.47.1.3.2.1.6 | TruthValue | read-write | This object can hold modem out of service and marks the modem as suspected or proven to be bad. During the router start-up initialization sequence, modem back-to-back tests will test modems and mark those modems failing tests as bad modems. The management entity also can use this command to lock out the suspicious modem or unlock the modem to do further debugging or test. This command will be used accompanied with cmholdReset command to put modem out of service. This command doesn't do the reset. For a normally good modem, it can start handling calls after it exits from modem reset mode. For a bad modem, it cannot start handling calls after it exits from modem reset mode. The manager needs to take modem out of bad modem mode in order to handle calls. This object is only valid when cmState is onHook or busiedOut. The value of true(1) indicates the modem is suspected to be bad and its state is set to bad. The value of false(2) indicates the modem has not been suspected to be bad or has been re-marked as good. |

If the modem to be busyout is handling a call, the busyout action will be taken after the current call is disconnected. After modem is busyout, the following commands can be applied to those modems - reset, bad modem, download modem firmware, etc. This is called nice or graceful busyout. The value of true(1) indicates the busyOut request has been issued to the modem, but the busyout could be pending. The management entity needs to query the cmState to see if the modem is successfully busied out. The value of false(2) indicates the modem is not given the busyOut command. |
