Description: Manages error-disable recovery timers and automatic port re-enablement on Dell network switches.
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 Dell-ERRDISABLE-RECOVERY-MIB?
This Dell private MIB manages the err-disable recovery feature, which automatically re-enables switch ports that were administratively shut down due to a detected error condition such as a security violation, loop, or BPDU-guard trigger. It exposes a global recovery interval, per-cause enable flags, and a per-interface table showing the specific err-disable reason and whether auto-recovery is enabled for that port. It is directly a hardware/port-fault monitoring tool: the err-disable reason code on a given interface reveals exactly why that port was shut down, which is central to diagnosing physical or security-related port faults. It operates alongside the standard IF-MIB port status objects for the same interfaces. The Dell-ERRDISABLE-RECOVERY-MIB MIB is typically deployed on Dell access and aggregation switches that use automated port-protection mechanisms like BPDU guard or storm control.
IPNetwork Monitor allows you to monitor SNMP objects defined in Dell-ERRDISABLE-RECOVERY-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
- Dell network switch (PowerConnect/N-Series family)
Monitoring Examples
An administrator investigating a down port polls rlErrdisableRecoveryIfTable/rlErrdisableRecoveryIfEntry, checking rlErrdisableRecoveryIfReason to identify the triggering cause and rlErrdisableRecoveryIfEnable to see if auto-recovery is armed for that port. The rlErrdisableRecoveryCauseTable shows which causes are globally enabled for auto-recovery, and rlErrdisableRecoveryInterval indicates how long until the port will automatically attempt to come back up. Repeated recurrence of the same reason on a port would point to a persistent physical or configuration problem rather than a transient event.
What Can Be Monitored
- per-interface err-disable reason
- err-disable auto-recovery enable state
- global recovery interval
- per-cause recovery enable flags
