Description: Provides management objects for Extreme Networks network processor (NP) card information, covering hardware status and statistics of switching ASICs.

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 EXTREME-NP-MIB?

EXTREME-NP-MIB is an Extreme Networks proprietary MIB reporting Network Processor (NP) card status on modular Extreme switch chassis. Its module table, keyed by slot, records description, current/primary/secondary software version, boot-ROM version, and processor state, while an SMA (Switch Management Agent) table reports protocol/service version, uptime, CPU/memory utilization, and broadcast/listener packet and byte counters, alongside an ATM-cell-PDU table for ATM-capable modules. As a hardware/performance-status MIB it lets an administrator watch an NP card's CPU/memory utilization and confirm its processor state before a firmware upgrade. It is deployed on modular Extreme Networks switch chassis with NP line cards. Engineers can download the EXTREME-NP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EXTREME-NP-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

  • Modular Extreme Networks switch chassis (NP line cards)

Monitoring Examples

An administrator monitors extremeSMACpuUtilization and extremeSMAMemUtilization per slot to catch an NP line card approaching a resource limit on a modular Extreme Networks chassis.

What Can Be Monitored

  • NP card CPU/memory utilization and processor state

How to Use in IPNetwork Monitor

Example using extremeSMABytesBroadcaster OID:

Select a Modular Extreme Networks switch chassis, Network Processor line card 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 extremeSMABytesBroadcaster into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The total number of media bytes received from the broadcasters. 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 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.
