Description: Alcatel OmniSwitch dual-home link MIB for configuring active/standby uplink redundancy without STP.

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 ALCATEL-IND1-DHL-MIB?

ALCATEL-IND1-DHL-MIB is an Alcatel-Lucent OmniSwitch enterprise MIB for the Dual Homed Link (DHL) feature, which provides active/standby uplink redundancy by splitting a pool of VLANs across two links without relying on Spanning Tree Protocol. Because STP is implicitly disabled on DHL links, the exposed data centers on configuration of link pairing and VLAN-to-link assignment rather than generic interface counters. Its monitoring relevance is primarily software/protocol status: an operator would confirm which of the two redundant links is currently carrying a given VLAN's traffic and whether a failover has occurred, since DHL substitutes for STP's normal failure detection. No specific object names were extractable for this module, so its exact table structure cannot be detailed, but it conceptually depends on VLAN membership rather than an external standard. It would be deployed at the network edge of OmniSwitch installations requiring dual-homing to two upstream switches without running STP, where ALCATEL-IND1-DHL-MIB SNMP monitoring confirms which link is active and whether a failover has occurred.

IPNetwork Monitor allows you to monitor SNMP objects defined in ALCATEL-IND1-DHL-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.

Alcatel-Lucent OmniSwitch edge switches

Monitoring Examples

No sample objects were available for this module, so a concrete polling example naming real table or object identifiers cannot be given honestly. Conceptually, based on the module description, an operator would check per-link active/standby state and per-VLAN link assignment to confirm failover behavior, but the underlying object names are not confirmed here.

What Can Be Monitored

active/standby link state
VLAN-to-link assignment
failover occurrence

OIDs

OID symbolic	OID numeric	Type	Access	Description
alcatelIND1DHLMIB	1.3.6.1.4.1.6486.801.1.2.1.65.1			The Dual Homed Link uses two links with a number of VLANs split between them from the common pool of vlans, in such a way that any vlan is not associated with both of the redundant links at the same time to avoid formation of loops and also VLANs are still connected to the core when one link fails. STP is disabled on both the DHL links implicitly.
