Description: Monitors Cabletron SSR hardware components including line cards, power supplies, and fan tray status.

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 CTRON-SSR-HARDWARE-MIB?

CTRON-SSR-HARDWARE-MIB is a Cabletron (later Enterasys) enterprise MIB module written for the SmartSwitch Router (SSR) family of Layer 3 switching/routing chassis. It exposes hardware-inventory style data organized under a system hardware group, covering the physical components of the chassis such as line cards, power supplies, and fan trays. The module is explicitly aimed at monitoring the physical health of the device, letting a management station detect failed or missing power supplies, fan tray faults, or line-card presence/status changes that would otherwise go unnoticed until a service outage. Network engineers supporting legacy Cabletron/Enterasys SSR chassis often need a CTRON-SSR-HARDWARE-MIB download from vendor or community MIB archives, since the module is no longer distributed with current management software. It follows the standard SNMPv2 conformance pattern (object groups, compliance statements) layered on top of a vendor hardware group, and it depends on the base SNMPv2-SMI/SNMPv2-CONF framework for its group and compliance definitions rather than any other functional MIB. It is deployed on Cabletron/Enterasys SSR chassis-based routers in enterprise and carrier network closets where continuous hardware-fault polling is needed.

IPNetwork Monitor allows you to monitor SNMP objects defined in CTRON-SSR-HARDWARE-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.

Monitoring Examples

Using the sysHwGroup branch, an operator would poll per-slot power-supply and fan-tray status objects to confirm every field-replaceable unit in the SSR chassis is present and operating normally, alerting if a fan tray or power supply entry reports a failed state. The hwGroups/hwCompliances/hwConformance objects define which of these hardware objects an agent must implement, rather than exposing data themselves. A sudden absence of an expected line card or a change in reported hardware status would signal a card reseat, hot-swap event, or component failure worth investigating.

What Can Be Monitored

FAQ

How would CTRON-SSR-HARDWARE-MIB alert me to a failed power supply on a Cabletron/Enterasys SSR chassis?
It exposes power supply status under its system hardware group, letting a management station detect a failed or missing power supply that would otherwise go unnoticed until it caused an outage.

What other physical components does CTRON-SSR-HARDWARE-MIB track besides power supplies?
It also covers fan tray status and line-card presence/status, so continuous polling can flag fan tray faults or a line card going missing or changing state in the SSR chassis.
