Description: HP ICF SNMP MIB for daisy-chain stacking management of HP ProCurve devices connected in a physical chain topology.

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 HP-ICF-CHAIN?

HP-ICF-CHAIN is an HP (Hewlett-Packard Networking) vendor-specific MIB under the HP-ICF-OID hpicfCommon tree that models HP's Distributed Management Chain - a daisy-chained physical stacking topology used on HP AdvanceStack-era devices - rather than exclusively modern ProCurve hardware as the hint suggests, given its earliest revisions date to 1994. Scalars hpicfChainMaxMembers, hpicfChainCurMembers, hpicfChainLastChange, and hpicfChainChanges summarize how many boxes are on the chain and when membership last changed, while hpicfChainTable (indexed by hpicfChainId, typically a serial number or MAC address) lists every box on the chain with its hpicfChainObjectId (device type), hpicfChainTimestamp, hpicfChainHasAgent flag, hpicfChainThisBox flag, and an operator-assignable hpicfChainLocation ordering value. A companion hpicfChainViewTable lists the boxes a given agent can proxy SNMP requests to on behalf of agent-less chain members. The single current notification, hpicfChainRemoval, reports when a box leaves the chain (the original hpicfChainAddition trap is deprecated in favor of relying on Cold Start). It is deployed on HP AdvanceStack/ProCurve devices connected in a physical management chain, and administrators download the HP-ICF-CHAIN file to track chain membership and proxy topology.

IPNetwork Monitor allows you to monitor SNMP objects defined in HP-ICF-CHAIN. 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 AdvanceStack/ProCurve devices in a Distributed Management Chain stack

Monitoring Examples

An operator polls hpicfChainCurMembers against hpicfChainMaxMembers and walks hpicfChainTable for hpicfChainHasAgent flags, and an unexpected drop in hpicfChainCurMembers paired with an hpicfChainRemoval trap would indicate a box was physically disconnected from the management chain.

What Can Be Monitored

chain member count and maximum capacity
per-box chain membership table (ID, object ID, timestamp)
agent presence and proxy view table
chain location ordering
chain removal notifications

T/F hpicfChainHasAgent	1.3.6.1.4.1.11.2.14.11.1.1.5.1.4	TruthValue	read-only	This object will contain the value 'true' if this box contains at least one network management agent capable of responding to SNMP requests, and will contain the value 'false' otherwise.
OCT hpicfChainId	1.3.6.1.4.1.11.2.14.11.1.1.5.1.1	OCTET STRING	read-only	An identifier which uniquely identifies this particular box. In practice, this will be a box serial number or MAC address.
hpicfChainingCompliance	1.3.6.1.4.1.11.2.14.10.2.2.1.1.1			The compliance statement for HP ICF devices with a Distributed Management Chain connection.
hpicfChainingCompliance2	1.3.6.1.4.1.11.2.14.10.2.2.1.1.2			The compliance statement for HP ICF devices with a Distributed Management Chain connection.

The intent is that a management station can use it to assign an ordering to boxes on the chain that can later be used when displaying the chain.
I32 hpicfChainMaxMembers	1.3.6.1.4.1.11.2.14.11.1.1.1	Integer32	read-only	The maximum number of devices that can be supported on the Distributed Management Chain from this agent.

TIM hpicfChainTimestamp	1.3.6.1.4.1.11.2.14.11.1.1.5.1.3	TimeStamp	read-only	The value of the agent's sysUpTime at which this box was last initialized. If the box has not been initialized since the last reinitialization of the agent, then this object has a zero value.
hpicfChainTrapGroup	1.3.6.1.4.1.11.2.14.10.2.2.1.2.2			******* THIS GROUP IS OBSOLETE ******* A collection of notifications used to indicate a changes in membership on a Distributed Management Chain.

OCT hpicfChainViewId	1.3.6.1.4.1.11.2.14.11.1.1.6.1.1	OCTET STRING	read-only	An identifier which uniquely identifies this particular box. In practice, this will be a box serial number or MAC address.
STR hpicfChainViewName	1.3.6.1.4.1.11.2.14.11.1.1.6.1.2	DisplayString	read-only	The local name of this box. This is used by the proxy agent for the box to determine which box on the Distributed Management Chain is being addressed. If an agent does not use this method to distinguish proxy destinations, it should return a zero length octet string for this object. For SNMPv1, the destination box is specified by appending this name to the proxy agent's community name. For example, if this agent has a community with a community name of 'public', and the value of this object is 'repeater1', the community 'public/repeater1' will specify that the agent should proxy to the public community of the 'repeater1' box. The default value for this object for box-level repeaters is an ASCII hex representation of the low-order three bytes of the device MAC address.
hpicfChainViewTable	1.3.6.1.4.1.11.2.14.11.1.1.6		not-accessible	This table contains one entry for each box on the Distributed Management Chain for which this agent is able to act as a proxy.
