Description: Enterasys Networks MIB for configuring firmware image validation and automatic recovery procedures on Enterasys devices.
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 ENTERASYS-IMAGE-VALIDATION-MIB?
ENTERASYS-IMAGE-VALIDATION-MIB is a proprietary Enterasys Networks MIB for configuring automatic validation of a newly loaded firmware image and triggering recovery if the new image fails to establish reachability. It exposes objects controlling whether validation is enabled, the validation time period, the specific validation operations (e.g., ICMP ping, SNMP reachability check) to run, and the target addresses used for those checks. Its monitoring relevance is around software/firmware reliability: it lets an administrator confirm that image-validation safeguards are active and correctly targeted before a firmware upgrade, reducing the risk of a device becoming unreachable after an update and requiring a truck roll, which is effectively a software-upgrade health-check configuration. It is a vendor-specific safeguard MIB with no stated dependency on a standard IETF MIB. It is deployed on Enterasys/Extreme Networks switches and routers during firmware upgrade operations, especially on remote or unattended sites. Network engineers evaluating or troubleshooting this functionality can download the ENTERASYS-IMAGE-VALIDATION-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in ENTERASYS-IMAGE-VALIDATION-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
- Enterasys/Extreme Networks switch or router
Monitoring Examples
Before pushing a firmware upgrade to a remote switch, an administrator would confirm etsysImageValidationEnable is set and etsysImageValidationPeriod gives enough time for the new image to boot and be tested, then verify etsysImageValidationIcmpAddress and etsysImageValidationSnmpAddress point to a reachable management station so the validation check can succeed. etsysImageValidationOperations would be checked to confirm which specific checks (ICMP, SNMP, or both) are configured to run, since a misconfigured target address here would cause the device to falsely conclude the new image failed and roll back unnecessarily. This is a pre/post-upgrade safeguard configuration MIB rather than a general runtime monitoring one.
What Can Be Monitored
- image validation enabled state
- validation time period
- validation check type (ICMP/SNMP)
- validation target addresses
