MARVELL-ERRDISABLE-RECOVERY-MIB

Description: Marvell Semiconductor MIB defining error-disable recovery configuration objects for automatically re-enabling switch ports after error conditions.

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.

MARVELL-ERRDISABLE-RECOVERY-MIB is a Marvell Semiconductor private MIB implemented on switches built around Marvell switching silicon, used to configure and monitor the "errdisable recovery" feature that automatically re-enables switch ports that were administratively shut down due to error conditions. It exposes a global rlErrdisableRecoveryInterval and rlErrdisableRecoveryEnable setting, a rlErrdisableRecoveryCauseTable listing which error causes (e.g., BPDU guard, loopback detection) are eligible for auto-recovery, and a rlErrdisableRecoveryIfTable tracking per-interface recovery reason and enable state. For status monitoring it is directly useful for port/hardware-fault visibility: rlErrdisableRecoveryIfReason reveals why a specific port was error-disabled, letting an operator diagnose recurring link faults, while the recovery-interval setting governs how quickly the switch attempts self-healing. It builds on the broader "errdisable" concept common across enterprise switch MIBs (paralleling IF-MIB ifOperStatus semantics for the disabled state) rather than a specific IETF standard. It is deployed on switches using Marvell chipsets (common in white-box and vendor OEM switch platforms) in campus/data-center access-layer environments. Network engineers evaluating or troubleshooting this functionality can download the MARVELL-ERRDISABLE-RECOVERY-MIB file directly to load it into their MIB browser.

An administrator would poll rlErrdisableRecoveryIfTable to see rlErrdisableRecoveryIfReason and rlErrdisableRecoveryIfEnable for each interface, cross-checked against rlErrdisableRecoveryCauseTable to know which causes are configured for auto-recovery, and rlErrdisableRecoveryInterval for the recovery timer. A port repeatedly showing an errdisable reason like "loopback" every rlErrdisableRecoveryInterval seconds would indicate a persistent physical loop or misbehaving connected device rather than a one-off fault.
