What Is USB-MIB?
USB-MIB is a 3Com proprietary MIB describing USB interfaces and attached devices on 3Com network equipment. Its port table, keyed by index, records port type and rate, a device table records power draw, vendor/product ID, configuration count, active USB class, status, enumeration counter, and remote-wakeup support/current state, and a CDC (Communications Device Class) table records subclass, version, and data-transfer type for USB modem/networking devices. As a hardware-inventory MIB it lets an administrator confirm which USB device (by vendor/product ID) is attached to a given port and its enumeration status. It is deployed on 3Com network equipment with USB ports (e.g., for USB modem failover). Engineers can download the USB-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in USB-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.
What Can Be Monitored
- attached USB device identity and enumeration status
Supported Devices
- 3Com network equipment (USB ports)
Monitoring Examples
An administrator checks usbDeviceVendorID and usbDeviceStatus to confirm a USB backup modem is correctly recognized and enumerated on a 3Com device's USB port.
