Description: Tracks error-disabled port states and recovery settings on D-Link 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 DLINKSW-ERROR-DISABLE-MIB?

This is a D-Link proprietary MIB tracking error-disabled port states and their recovery settings on D-Link switches, the mechanism by which a switch automatically shuts down a port after detecting a fault condition (such as a loop, security violation, or storm) and optionally auto-recovers it after a timeout. It exposes status showing which ports are currently error-disabled and why, plus configuration for auto-recovery enable/disable and recovery interval per cause. For monitoring hardware/software status, this MIB is directly about fault detection; polling the error-disabled port list and its cause reveals ports taken down due to loops, BPDU guard violations, or other faults, and confirming auto-recovery settings ensures a transient fault doesn't leave a port permanently down. It is a vendor-private feature that parallels error-disable/recovery concepts common across switch vendors, without a direct single IETF MIB dependency. It is deployed on D-Link switches to help operators quickly identify and, where appropriate, automatically remediate faulted ports. Engineers can download the DLINKSW-ERROR-DISABLE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DLINKSW-ERROR-DISABLE-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.

Monitoring Examples

No sample object names were provided for this module, so specific OIDs cannot be cited here. Based on its description, a realistic scenario is polling the list of currently error-disabled ports along with the triggering cause (e.g., loop detection, BPDU guard, storm control) and checking whether auto-recovery is enabled and its timer, to catch a port that has been down for an unexpectedly long time due to a disabled auto-recovery setting.

What Can Be Monitored

error-disabled port list
error-disable cause per port
auto-recovery enable state and interval

OIDs

OID symbolic	OID numeric	Type	Access	Description
dlinkSwErrDisableMIB	1.3.6.1.4.1.171.26.45			This MIB module defines objects for error disabled.
dErrDisableMIBNotifications	1.3.6.1.4.1.171.26.45.0
NTF dErrDisNotifyPortDisabledAssert	1.3.6.1.4.1.171.26.45.0.1			The trap is sent when a port enters into error disabled state.
NTF dErrDisNotifyPortDisabledClear	1.3.6.1.4.1.171.26.45.0.2			The trap is sent when a port loop restarts after the interval time.
NTF dErrDisNotifyVlanDisabledAssert	1.3.6.1.4.1.171.26.45.0.3			The trap is sent when a Port with a VID loop occurs.
NTF dErrDisNotifyVlanDisabledClear	1.3.6.1.4.1.171.26.45.0.4			The trap is sent when a Port with a VID restarts after the interval time.
dErrDisableMIBObjects	1.3.6.1.4.1.171.26.45.1
dErrDisRecoveryTable	1.3.6.1.4.1.171.26.45.1.1		not-accessible	This table contains the recovery mechanism for the features with error-disable functionality. Transceiver monitoring module (the DErrDisReasonID is 'ddm') can also put a SFP port which is in abnormal status in error disabled state. This error disable cannot be auto recovered but can only be manually recovered. As a result, there is no entry for error cause is 'ddm' in this table.
dErrDisRecoveryEntry	1.3.6.1.4.1.171.26.45.1.1.1		not-accessible	An entry is created for each feature which has error-disable functionality.
DER dErrDisRecoveryIndex	1.3.6.1.4.1.171.26.45.1.1.1.1	DErrDisReasonID	not-accessible	This object indicates the cause of error-disable.
T/F dErrDisRecoveryEnable	1.3.6.1.4.1.171.26.45.1.1.1.2	TruthValue	read-write	This object specifies whether the system can automatically recover a system entity that has been disabled by the cause.
I32 dErrDisRecoveryInterval	1.3.6.1.4.1.171.26.45.1.1.1.3	Integer32	read-write	Specifies the error-recovery time interval on specific cause to recover the port/interface from the error disabled situation.
U32 dErrDisIfStatusTableNum	1.3.6.1.4.1.171.26.45.1.2	Unsigned32	read-only	Indicates the number of entries present in the dErrDisIfStatusTable.
dErrDisIfStatusTable	1.3.6.1.4.1.171.26.45.1.3		not-accessible	This table provides next recovery timeout information about an interface disabled by a feature.
dErrDisIfStatusEntry	1.3.6.1.4.1.171.26.45.1.3.1		not-accessible	An entry indicates next recovery timeout information about an interface or (interface, vlan) disabled by a feature.

VLA dErrDisIfStatusVlanIndex	1.3.6.1.4.1.171.26.45.1.3.1.2	VlanIdOrNone	not-accessible	This object indicates the VLAN in the given interface that has been error-disabled. If the physical interface is error-disabled then the value of this object is 0.
DER dErrDisIfStatusDisReasonIndex	1.3.6.1.4.1.171.26.45.1.3.1.3	DErrDisReasonID	not-accessible	This object indicates the reason which cause the interface disabled.
