Description: Brocade/Foundry Networks agent MIB for managing and monitoring ServerIron and NetIron chassis devices, including hardware inventory, CPU/memory utilization, temperature, and system configuration.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring FOUNDRY-SN-AGENT-MIB with a free 30-day trial of IPNetwork Monitor.

What Is FOUNDRY-SN-AGENT-MIB?

FOUNDRY-SN-AGENT-MIB is a Brocade/Foundry Networks agent MIB used to manage and monitor ServerIron and NetIron chassis-based switching and load-balancing platforms. It exposes hardware-inventory data (chassis type, serial number, main/expansion board descriptions and port counts), environmental status (power supply and fan status), status/traffic/media LED indicators, and system configuration/trap-enable controls. Its monitoring emphasis is clearly on hardware health: administrators rely on it for power supply and fan status to catch cooling or power failures, chassis serial number and type for asset tracking, and port totals on main/expansion boards to verify hardware inventory matches expectations, with configurable traps (e.g., power-supply trap enable) tying these states into fault notifications. It works alongside Brocade/Foundry's broader agent and interface MIBs, and standard MIB-II, for a complete picture of device health. Any FOUNDRY-SN-AGENT-MIB OID under the chassis or environmental branches is worth including in fault-monitoring templates, since it directly reflects power, fan, or board-level hardware conditions. It is deployed on Brocade (formerly Foundry) ServerIron application-delivery switches and NetIron routing/switching chassis in data center and service-provider networks.

IPNetwork Monitor allows you to monitor SNMP objects defined in FOUNDRY-SN-AGENT-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

  • Brocade/Foundry ServerIron application-delivery switches
  • Brocade/Foundry NetIron routing/switching chassis

Monitoring Examples

An admin would poll snChasPwrSupplyStatus and snChasFanStatus to detect a failed power supply or stalled fan before it causes thermal shutdown, and snChasSerNum/snChasType to confirm chassis identity during an inventory audit. snChasMainBrdDescription and snChasMainPortTotal (plus the expansion-board equivalents) reveal whether an expected line card or expansion module is present and correctly recognized, while snChasEnablePwrSupplyTrap controls whether a power-supply fault actually generates an SNMP trap to the NMS.

What Can Be Monitored

  • power supply status
  • fan status
  • chassis type and serial number
  • main/expansion board port totals
  • status/traffic/media LED indicators
  • power-supply trap enablement

How to Use in IPNetwork Monitor

Example using snChasActualTemperature OID:

Select a Brocade/Foundry ServerIron/NetIron chassis platform 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 snChasActualTemperature into the Find box to locate it in the OID tree, then select it and click OK. It reports the chassis temperature, in units of 0.5°C, from the management module's temperature sensor. 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 an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the reported value exceeds the level expected for healthy operation, since sustained high chassis temperature often precedes thermal shutdown or hardware degradation. Click Finish to create the monitor; you can adjust any parameter later.
