Description: Alcatel OmniSwitch IPv6 management MIB for interface addresses, neighbor discovery, and IPv6 forwarding 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-IPV6-MIB?

ALCATEL-IND1-IPV6-MIB is Alcatel's proprietary OmniSwitch MIB for configuring and monitoring IPv6 functionality on the switch, including interface addressing, neighbor discovery, and tunneling. It exposes an interface table for IPv6-enabled VLANs/interfaces, global neighbor-discovery parameters such as stale lifetime and neighbor limits per system and per VRF, a Path MTU discovery control table, and tunnel configuration objects. Its monitoring role is chiefly software/configuration-state visibility for the IPv6 stack — confirming interfaces are correctly enabled and addressed, that neighbor caches haven't hit configured limits, and that PMTU entries are behaving as expected — rather than physical hardware status. It builds on IPv6 concepts defined by IETF standards, such as neighbor discovery and PMTU discovery, while implementing them as Alcatel-proprietary objects rather than depending on an IETF IPv6 MIB directly. It's deployed on Alcatel/Alcatel-Lucent OmniSwitch platforms wherever IPv6 routing or dual-stack VLAN interfaces are enabled. Engineers can download the ALCATEL-IND1-IPV6-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ALCATEL-IND1-IPV6-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 with IPv6 routing enabled

Monitoring Examples

An engineer would poll alaIPv6InterfaceTable and check alaIPv6InterfaceRowStatus to confirm a VLAN's IPv6 interface is active, then review alaIPv6NeighborLimit and alaIPv6NeighborVRFLimit against actual neighbor-cache usage to catch a system approaching its neighbor-discovery capacity. alaIPv6NeighborStaleLifetime and alaIPv6PMTUMinLifetime govern how long neighbor and PMTU cache entries persist before re-verification, which matters when diagnosing stale-neighbor connectivity issues. Administrative actions like alaIPv6ClearNeighbors or alaIPv6ClearTraffic are typically invoked to force a fresh neighbor discovery cycle when troubleshooting an IPv6 reachability problem.

What Can Be Monitored

  • IPv6 interface status
  • neighbor discovery cache limits/usage
  • PMTU cache lifetime/entries
  • IPv6 tunnel configuration
  • neighbor/traffic clear operations

How to Use in IPNetwork Monitor

Example using alaIPv6PMTUHits OID:

Select an Alcatel/Alcatel-Lucent OmniSwitch 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 alaIPv6PMTUHits 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 number of times the path MTU entry has been used. 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.
