Description: Extreme Networks MIB for virtual machine awareness, tracking VM-to-port associations for network edge virtualization.

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-VM-MIB?

This Extreme Networks MIB provides virtual machine awareness on Extreme switches, tracking which virtual machines are associated with which physical switch ports to support network edge virtualization and VM mobility visibility. It exposes VM-to-port association data, letting the switch's management plane report which VMs are currently connected at the network edge. For monitoring purposes it supports detecting VM migration events (an association moving from one port to another) and identifying orphaned or unexpected VM-to-port bindings — a software/inventory-status use case rather than classical hardware health monitoring. It likely depends on IEEE 802.1Qbg/VDP-style discovery mechanisms and standard ENTITY/IF-MIB port indexing for the physical port references. Typically deployed on Extreme Networks switches in virtualized data center environments where server virtualization requires network-edge VM visibility, and administrators can download the EXTREME-VM-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EXTREME-VM-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 data center switches

Monitoring Examples

No sample_objects were extracted for this module, so specific table names cannot be cited, but based on the description an administrator would poll the VM-to-port association data to see which VM identifiers are currently mapped to which switch port, and would notice a VM's entry disappear from one port and appear on another as evidence of a live migration event, or an unexpected mapping indicating a rogue VM.

What Can Be Monitored

VM-to-switch-port association
VM migration/mobility events
virtual machine identity at network edge

How to Use in IPNetwork Monitor

Example using extremeVMDetectedNumber OID:

Select an Extreme Networks data center switch (VM-to-port association tracking) 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 extremeVMDetectedNumber into the Find box to locate it in the OID tree, then select it and click OK. The number of virtual machines detected on this switch. 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 Gauge32-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.
