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 SSG-5000-CHASSIS-MIB?

SSG-5000-CHASSIS-MIB is a vendor-specific MIB, originally from Shasta Networks and later Nortel (via the Shasta acquisition), for monitoring the hardware health of the SSG-5000 broadband service gateway chassis. It exposes system-wide health indicators covering fans, temperature, packet/cell forwarding fabric, and CPU load on the chassis management controller. It is explicitly a hardware/system-health MIB: ssg5000SysFanStatus and ssg5000SysTempStatus report cooling and thermal health, ssg5000SysStatus gives overall system status, and ssg5000CmcCPUIdleTics5Sec/ssg5000CmcCPUTotalTics5Sec (plus reboot-tracking counters) expose the chassis management CPU's load, together forming a solid picture of the box's physical and processing health. It is a self-contained enterprise MIB built around its own chassis/system-health object groups without heavy reliance on other MIBs. It is deployed by service providers operating SSG-5000 broadband gateways to watch for fan, thermal, fabric, or CPU-related faults that could threaten service continuity. Engineers can download the SSG-5000-CHASSIS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SSG-5000-CHASSIS-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

  • Nortel/Shasta Networks SSG-5000 broadband service gateway

Monitoring Examples

An admin would poll ssg5000SysFanStatus and ssg5000SysTempStatus to confirm cooling and temperature are within normal range, and ssg5000CmcCPUIdleTics5Sec versus ssg5000CmcCPUTotalTics5Sec to compute recent CPU utilization on the chassis management controller. Rising ssg5000SysFabricCellsDropped or ssg5000SysPacketsDropped/ssg5000SysCellsDropped alongside high ssg5000SysFabricMemUtilization would indicate the switching fabric is becoming congested or memory-constrained, a leading indicator of service degradation before ssg5000SysActiveAccessConn/ssg5000SysActiveTrunkConn connection counts start dropping.

What Can Be Monitored

  • fan status
  • temperature status
  • fabric cell/packet drops
  • fabric memory utilization
  • chassis management CPU utilization
  • active access/trunk connection counts

How to Use in IPNetwork Monitor

Example using ssg5000SysFabricCellsDropped OID:

Select a Nortel/Shasta Networks SSG-5000 broadband service gateway chassis 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 ssg5000SysFabricCellsDropped into the Find box to locate it in the OID tree, then select it and click OK. It reports the number of ATM cells dropped at system fabric. 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 between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
