Category: Device Management, Vendor: Extreme Networks

Description: Contains common system-level objects for Extreme Networks switches, including system identification, configuration save/restore status, and basic platform information.

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

What Is EXTREME-SYSTEM-MIB?

EXTREME-SYSTEM-MIB is an Extreme Networks proprietary MIB providing common system-level management objects shared across Extreme's switch product lines. It exposes platform-wide data such as system identification, image/firmware feature information, configuration save/restore status, and system-level trap definitions. It is directly useful for monitoring device software status: the extremeImageFeatureTable lets an operator confirm which firmware image and feature set is active, while system notification/trap objects report events like configuration changes or save failures that indicate operational health issues. This kind of EXTREME-SYSTEM-MIB SNMP monitoring is typically combined with the vendor's VLAN, chassis, and port-specific MIBs to build a complete operational picture of a given switch. It is a base/common MIB that other Extreme Networks product-specific MIBs (VLAN, chassis, port) build on top of. It is deployed across Extreme Networks Ethernet switch and routing platforms in enterprise and data-center networks.

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

Extreme Networks 5420 Series (current) — stackable edge switches, 24/48-port, up to 90W PoE
Extreme Networks 4000 Series (current) — Layer 2 campus/branch switches

Monitoring Examples

An administrator polls extremeImageFeatureTable to verify which software image and feature license is currently running on the switch, useful for confirming a firmware upgrade took effect. Traps generated under extremeSystemTrapsPrefix (rooted through extremeSystemNotifications) alert on events such as configuration-save failures or system state changes, which an NMS would correlate with unexpected reboots or config drift. Because this is a common/base MIB, its objects are typically polled alongside chassis- and port-specific Extreme MIBs for a full system health picture.

How to Use in IPNetwork Monitor

Example using extremeCpuAggregateUtilization OID:

Select an Extreme Networks switch or wireless controller 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 extremeCpuAggregateUtilization into the Find box to locate it in the OID tree, then select it and click OK. It reports the aggregate CPU utilization since the switch started executing. 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 CPU utilization exceeds 85%, a common warning threshold before sustained high load affects switching performance. Click Finish to create the monitor; you can adjust any parameter later.

FAQ

How can EXTREME-SYSTEM-MIB confirm which firmware is running on an Extreme switch?
Its extremeImageFeatureTable lets an operator check which firmware image and feature set is currently active on the device.

What does this MIB report when a configuration save fails on an Extreme switch?
It includes system-level trap and notification objects that report events such as configuration changes or save failures, which operators can use to flag operational health issues alongside the vendor's VLAN, chassis, and port-specific MIBs.
