Description: Raisecom SNMP keepalive MIB that periodically sends heartbeat traps with device identity and interface details to confirm reachability of Raisecom devices

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 RAISECOM-KEEPALIVE-MIB?

RAISECOM-KEEPALIVE-MIB is a private MIB from Raisecom that implements an SNMP keepalive mechanism, periodically sending heartbeat traps containing device identity and interface details to confirm a Raisecom device remains reachable and operational. Rather than exposing tables of polled data, it centers on trap-based fault/reachability notification, making it a monitoring MIB focused squarely on device availability. It directly supports monitoring of overall device operational status by proving the management agent and its network path are alive, which is a proxy for basic software/system health. It has no strong dependency on other MIBs beyond standard SNMP trap infrastructure. It is typically deployed on remote or unmanned Raisecom access devices where a network management system needs assurance of continued reachability between scheduled polls. Network engineers evaluating or troubleshooting this functionality can download the RAISECOM-KEEPALIVE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RAISECOM-KEEPALIVE-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

Raisecom access/transmission devices

Monitoring Examples

A network management system would configure trap reception for the periodic keepalive trap and watch for its expected arrival interval; a missed keepalive trap from a given device identity would indicate the device has gone unreachable, lost power, or suffered an agent/software failure. The trap's included interface details help the NMS correlate the alert with the specific device and uplink interface reporting in.

What Can Be Monitored

periodic keepalive/heartbeat trap arrival
device identity in trap payload
interface details in trap payload

How to Use in IPNetwork Monitor

Example using raisecomKeepaliveTrapCounter OID:

Select a Raisecom access/transmission device 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 raisecomKeepaliveTrapCounter into the Find box to locate it in the OID tree, then select it and click OK. The value of this object indicates number of keepalive trap have sent. 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.
