Description: Alcatel OmniSwitch MIB covering multi-chassis link aggregation, including MC-LAG peer, port, and synchronization state.

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-MULTI-CHASSIS-MIB?

ALCATEL-IND1-MULTI-CHASSIS-MIB is Alcatel's proprietary OmniSwitch MIB for Multi-Chassis Link Aggregation (MC-LAG), enabling two physical chassis to act as a single logical switch for uplink redundancy. It exposes configuration objects such as chassis ID, hello interval, inter-chassis-protocol VLAN, and chassis group, alongside operational-state mirrors reporting the actual running chassis ID, role (primary/secondary), operational status, and chassis type. This is a hardware/software-state MIB in the sense that it directly monitors the health and role of the multi-chassis peering relationship — whether the peer link (IPC VLAN) is up, which chassis is currently acting as primary, and whether a loop-detection condition has been triggered. It's used alongside ALCATEL-IND1-CHASSIS-MIB for chassis/CMM redundancy and ALCATEL-IND1-HA-VLAN-MIB for uplink redundancy, as part of a broader OmniSwitch high-availability MIB family. It's deployed in Alcatel/Alcatel-Lucent OmniSwitch pairs configured for MC-LAG to provide loop-free, dual-homed connectivity to downstream devices or servers, and network engineers can download the ALCATEL-IND1-MULTI-CHASSIS-MIB file to load into a MIB browser for reference during configuration.

IPNetwork Monitor allows you to monitor SNMP objects defined in ALCATEL-IND1-MULTI-CHASSIS-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

  • Alcatel/Alcatel-Lucent OmniSwitch pair configured for MC-LAG

Monitoring Examples

An operator would poll multiChassisOperStatus and multiChassisOperChassisRole to confirm both chassis in an MC-LAG pair see the peering session up and agree on which one is primary versus secondary. multiChassisOperHelloInterval and multiChassisOperIpcVlan are checked against their configured counterparts, multiChassisConfigHelloInterval and multiChassisConfigIpcVlan, to catch a misconfigured inter-chassis link that could cause a split-brain condition. The multiChassisLoopDetection object is monitored for a triggered loop condition, which typically indicates a cabling error created an unintended loop between the two chassis.

What Can Be Monitored

  • multi-chassis peering operational status
  • chassis role (primary/secondary)
  • inter-chassis hello interval
  • IPC VLAN configuration
  • loop detection status
