Description: Manages Layer 3 switching and routing configuration including IP forwarding tables and route policy on Prominet-based platforms.

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 PROM-LAYER3-MIB?

PROM-LAYER3-MIB is a vendor MIB for Prominet-based Layer 3 switching platforms, covering Layer 3 switching and routing configuration including IP forwarding tables and route policy on the switch. Based on its short description, it is oriented toward the control-plane state of IP routing — forwarding table entries and route policy enforcement — used to manage inter-VLAN and IP routing rather than physical/environmental sensors. Functionally this supports software/routing status monitoring: verifying forwarding-table consistency and route-policy configuration helps detect misrouted traffic or forwarding errors. The available source excerpt for this MIB reveals only its IMPORTS clause with no concrete object or table names, so its full object structure could not be verified beyond the general description. It would typically be deployed on legacy Prominet-based Layer 3 switching hardware in enterprise campus networks. Engineers can download the PROM-LAYER3-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PROM-LAYER3-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

Prominet/Lucent Cajun Layer 3 switches

Monitoring Examples

The source excerpt for this MIB shows only an IMPORTS clause with no concrete object or table names (module_desc is empty), so a specific polling scenario cannot be described without inventing implausible identifiers. Based only on its short description, a Layer 3 MIB of this kind would typically expose an IP forwarding table and route-policy configuration objects that an operator would check to confirm routing decisions match expectations.
