Description: Alcatel OmniSwitch stack manager MIB for managing stacking topology, element roles, and stack ring configuration.

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-STACK-MANAGER-MIB?

ALCATEL-IND1-STACK-MANAGER-MIB is an Alcatel (Birds of Prey OmniSwitch line) enterprise MIB for managing switch stacking, where multiple physical chassis operate as one logical switch. It exposes topology data such as chassis role assignment, per-slot NI/CMM numbering, and the state of the redundant stacking-ring links between chassis. Its primary monitoring value is hardware/topology health: the chassis role (master/standby/idle) and chassis operational state reveal if a unit has failed or dropped out of the stack, while the A/B stacking-ring link states expose a broken redundant link before it causes a stack split. It is an Alcatel-proprietary module that is typically used alongside standard chassis/entity information rather than replacing it. It is deployed on stacked OmniSwitch installations in campus and edge networks that need chassis-level redundancy. Network engineers evaluating or troubleshooting this functionality can download the ALCATEL-IND1-STACK-MANAGER-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ALCATEL-IND1-STACK-MANAGER-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 stackable switches

Monitoring Examples

alaStackMgrChassisTable/alaStackMgrChassisEntry rows show alaStackMgrChasRole and alaStackMgrChasState per chassis, letting an admin detect a unit that has dropped to an unexpected role or gone non-operational. alaStackMgrLocalLinkStateA/alaStackMgrLocalLinkStateB together with alaStackMgrRemoteNISlotA/B and alaStackMgrRemoteLinkA/B reveal whether both redundant ring links to neighboring chassis are up, so a down link on side B while side A is up would flag a stack ring at risk of splitting.

What Can Be Monitored

stack chassis role (master/standby/idle)
chassis operational state
stacking ring link A/B status
remote NI slot/link mapping
overall stack topology health

How to Use in IPNetwork Monitor

Example using alaStackMgrStatPktsRx OID:

Select an Alcatel-Lucent Enterprise OmniSwitch switch as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type alaStackMgrStatPktsRx into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The total number of packets recieved on this port. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
