Description: HP ICF SNMP MIB for high availability management including redundant supervisor failover and HA state on HP ProCurve chassis switches.

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 HPICFHIGHAVAILABILITY-MIB?

HPICFHIGHAVAILABILITY-MIB is an HP proprietary SNMP module for managing high-availability redundant management modules on HP ProCurve modular chassis switches. It exposes failover state and history, along with per-management-module hardware state, covering the switch's dual-supervisor/redundant-controller subsystem. This MIB is squarely a hardware/software status monitoring module: hpicfHAFailOverState, hpicfHAFailOverTime, and hpicfHAFailOverReason report whether and why a failover occurred, while hpicfHAMgmtModuleTable's hpicfHAMgmtModuleState, hpicfHAMgmtModuleCardUpSince, hpicfHAMgmtModuleStateSince, and hpicfHAMgmtModuleRedundancyState/BackUpState report uptime and current role of each management module, directly reflecting device uptime and hardware redundancy health. It complements general chassis/entity MIBs (such as ENTITY-MIB) that would identify the physical modules this MIB reports state for. It is typically deployed on modular, dual-supervisor HP ProCurve chassis switches used in core/distribution roles where continuous uptime is critical. Engineers can download the HPICFHIGHAVAILABILITY-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HPICFHIGHAVAILABILITY-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

HP ProCurve modular chassis switch (dual-supervisor)

Monitoring Examples

An administrator would poll hpicfHAMgmtModuleTable, checking hpicfHAMgmtModuleState and hpicfHAMgmtModuleRedundancyState/BackUpState for each management module to confirm one is active and the other is a healthy standby, and hpicfHAMgmtModuleCardUpSince to see how long each module has been running. If hpicfHAFailOverState shows a recent failover, hpicfHAFailOverReason and hpicfHAFailOverTime would be checked to determine the cause (e.g., active module failure or manual switchover) and when it happened, which is critical for post-incident review of a chassis outage. A management module stuck in a non-standby, non-active state would indicate a hardware problem preventing proper redundancy.

What Can Be Monitored

failover state, time, and reason
management module operational state
module uptime (up-since)
redundancy/backup role of each module

How to Use in IPNetwork Monitor

Example using hpicfHAMgmtFailovers OID:

Select an HP ProCurve modular chassis switch (dual-supervisor high availability) 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 hpicfHAMgmtFailovers into the Find box to locate it in the OID tree, then select it and click OK. Specifies the number of management module failovers since last chassis boot. 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 between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
hpicfHighAvailability	1.3.6.1.4.1.11.2.14.11.1.11			Management information for configuring Redundant Management module on Hewlett-Packard network devices.
hpicfHAConfigObjects	1.3.6.1.4.1.11.2.14.11.1.11.1
INT hpicfHARedundancyManagementModuleMode	1.3.6.1.4.1.11.2.14.11.1.11.1.1	INTEGER	read-write	Specify to enable/disable this feature. Enabling allows for management module redundancy when there are two management modules in the switch and does a hitless failover. Disabling prevents redundancy except due to fatal hardware errors on one management module. warmStandby option does a non-hitless failover.
U32 hpicfHAContinuousFwdingTime	1.3.6.1.4.1.11.2.14.11.1.11.1.2	Unsigned32	read-write	This is a configurable timer. After the failover, on the new AMM, the route and neighbor table entries are marked as stale in the FIB. As routing protocols begin to re-add routes, this stale flag will be reset. When this timer expires, all route and neighbor table entries still marked stale [not yet re-added] will be removed. A value of 0 means that no layer 3 hitless behavior is desired, and in this configuration, upon failover all FIB entries are flushed and corresponding hardware entries are removed. A default value of 5 minutes is chosen with the assumption that the routing protocols can finish re-adding the routes to the equivalent state within this time.
hpicfHAStatusObjects	1.3.6.1.4.1.11.2.14.11.1.11.2
INT hpicfHAMgmtRedundancyFailureReason	1.3.6.1.4.1.11.2.14.11.1.11.2.1	INTEGER	read-only	Specifies the reason a redundant management module failed to become a standby module.

'unknown' indicates the state of the management module is undefined and this resource is unable to report standby state. 'active' indicates the state of the management module as active module and it means the resource is providing service. 'standby' indicates that the management module is not providing service, but it will be immediately able to take over the role of the resource to be backed up, without the need for initialization activity, and will contain the same information as the resource to be backed up.
I32 hpicfHAFailOverTime	1.3.6.1.4.1.11.2.14.11.1.11.2.4.1.4	Integer32	read-only	This object indicates the failover time in seconds since 1/1/1990 0:0:0.
INT hpicfHAFailOverReason	1.3.6.1.4.1.11.2.14.11.1.11.2.4.1.5	INTEGER	read-only	This object define the reason for failover. 'switchoverReq' indicates failover as a result of switchover command issued by the user. 'buttonReq' indicates failover as a result of manual boot done by the user via reboot button. 'crashReq' indicates failover as a result of crash that happened to the active module. 'activeReset' indicates failover as a result of reset command issued by the user at active module.

I32 hpicfHAMgmtModuleStateSince	1.3.6.1.4.1.11.2.14.11.1.11.2.5.1.3	Integer32	read-only	This object displays time in seconds from which the current state is valid.

'disabled' indicates the redundancy module is disabled. 'syncing' indicates the redundancy module is in syncing state and after successful syncing it will enter active state else it will report error.
