Dell-rlNicRedundancy

Description: Configures and monitors NIC redundancy and failover for management interfaces on Dell 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.

This Dell private enterprise MIB configures and reports on NIC redundancy/failover for the management network interface on Dell managed switches, allowing a switch to fail over its management connectivity between redundant physical NICs. It exposes a single primary configuration object - an enable/disable flag for the redundancy feature - rather than a broad data model. Its relevance to device monitoring is software/configuration status: confirming whether management-plane NIC failover protection is currently active, which affects the switch's resilience to a failed out-of-band management link. It has no notable dependency on external standard MIBs. It is used on Dell PowerConnect/N-series switches equipped with dual management NICs, in environments where continuous out-of-band manageability is a requirement. Network engineers evaluating or troubleshooting this functionality can download the Dell-rlNicRedundancy file directly to load it into their MIB browser.

An admin polls rlNicRedundancyEnable to verify that management NIC failover is turned on for a switch with dual out-of-band management ports, before relying on redundant connectivity during a planned network change. If the object unexpectedly reports disabled, it flags a configuration drift that could leave the device unreachable if the primary management NIC fails.
