What Is WAN-RESTORAL-REROUTE-MIB?

WAN-RESTORAL-REROUTE-MIB is an IBM-specific MIB (object prefix "ibm") for managing WAN link restoral and rerouting on IBM WAN access/routing equipment, tracking backup-link activation when a primary WAN circuit fails and the traffic rerouting that results. It exposes a primary-link restoral table with one row per monitored primary link, recording whether restoral is enabled, currently active, how long a restoral event lasted, and how many restoral attempts/successes have occurred, plus a companion table for rerouting events. From a monitoring standpoint it is squarely fault/failover oriented: an admin uses it to detect when a primary WAN link has failed and backup restoral kicked in, how many packets were forwarded during the outage, and whether restoral attempts are failing repeatedly, indicating a persistent link or hardware problem. It complements standard interface MIBs by referencing primary and secondary interface indexes, tying restoral state to specific network interfaces defined elsewhere (e.g., IF-MIB). It is deployed on IBM WAN routers/gateways in networks that use dual/backup WAN links for resiliency, such as branch routers with a primary leased line and a dial/backup circuit. Engineers can download the WAN-RESTORAL-REROUTE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in WAN-RESTORAL-REROUTE-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

Walking ibmWanRestoralTable (ibmWanRestoralEntry, indexed by ibmwrsPriNetifIndex/ibmwrsSecNetifIndex) and checking ibmwrsEnabled and ibmwrsActive tells an admin whether restoral is configured and currently engaged for a given primary/secondary link pair. ibmwrsDuration and ibmwrsAttempts/ibmwrsActuals reveal how long the current restoral event has lasted and how many restoral attempts have succeeded versus been tried, flagging a primary link that keeps failing to restore. ibmwrsFwdPkts shows how much traffic is being forwarded over the backup path, and the ibmWanRerouteTable (ibmWanRerouteEntry) tracks corresponding traffic-reroute events during the outage.

What Can Be Monitored

primary link restoral enabled/active state
restoral event duration
restoral attempt count and success count
packets forwarded during restoral
traffic reroute events
