Description: HP ICF SNMP MIB for proprietary switch stacking configuration, member management, and stack topology on HP ProCurve 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 HP-ICF-STACK?

HP-ICF-STACK is a Hewlett-Packard proprietary SNMP module for managing switch stacking on ProCurve devices, covering how multiple physical switches are joined into a single logically-managed stack. It exposes configuration and status objects describing stack membership, each member's role (commander/member), and stack topology. Its monitoring value is centered on hardware/software status of the stack fabric — detecting when a stack member drops out, changes role, or the stack topology otherwise changes unexpectedly, which typically signals a cabling or power issue on one unit. It is a standalone HP proprietary MIB with no dependency on a standard stacking MIB, since IEEE/IETF have no common stacking standard. It is deployed in wiring closets or data centers where several HP ProCurve switches are physically stacked and managed as one logical unit, with HP-ICF-STACK SNMP monitoring confirming every member stays active in the stack ring.

IPNetwork Monitor allows you to monitor SNMP objects defined in HP-ICF-STACK. 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

No object names were provided in the sampled source for this module, so specifics are inferred from its description rather than confirmed. In practice, an administrator would poll per-member status and role objects in this module to confirm all expected units are still active members of the stack, and would be alerted if a member's status changed to indicate it dropped out of the stack ring — a sign of a failed stacking cable or a power-cycled unit.

How to Use in IPNetwork Monitor

Example using hpicfStackActiveAgent OID:

Select an HP ProCurve stackable 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 hpicfStackActiveAgent into the Find box to locate it in the OID tree, then select it and click OK. It reports the entPhysicalIndex of the stack member currently acting as the active management agent for this switch stack. 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 an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the value changes unexpectedly, since that indicates the active-agent role failed over to a different stack member. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
hpicfStackMib	1.3.6.1.4.1.11.2.14.10.2.6			This MIB module contains object definitions for managing HP stackable devices.
hpicfStackConformance	1.3.6.1.4.1.11.2.14.10.2.6.1
hpicfStackCompliances	1.3.6.1.4.1.11.2.14.10.2.6.1.1
hpicfStackCompliance	1.3.6.1.4.1.11.2.14.10.2.6.1.1.1			The compliance statement for agents managing a stack of HP boxes.
hpicfStackGroups	1.3.6.1.4.1.11.2.14.10.2.6.1.2
hpicfStackBasicGroup	1.3.6.1.4.1.11.2.14.10.2.6.1.2.1			A collection of objects for managing boxes in a stack.
hpicfStackMultiAgentGroup	1.3.6.1.4.1.11.2.14.10.2.6.1.2.2			A collection of objects for managing redundant agents in a stack of HP boxes.
hpicfStack	1.3.6.1.4.1.11.2.14.11.1.5
hpicfStackBoxTable	1.3.6.1.4.1.11.2.14.11.1.5.1		not-accessible	This table contains a list of physical boxes currently in the stack.
hpicfStackBoxEntry	1.3.6.1.4.1.11.2.14.11.1.5.1.1		not-accessible	An entry containing information about a physical box in the stack. This table is indexed by the value of entPhysicalIndex that corresponds to the row in the entPhysicalTable for this box.
OCT hpicfStackBoxId	1.3.6.1.4.1.11.2.14.11.1.5.1.1.1	OCTET STRING	read-only	The box identifier that uniquely identifies this physical box. The value of this object is the serial number of the box.
STR hpicfStackBoxName	1.3.6.1.4.1.11.2.14.11.1.5.1.1.2	DisplayString	read-write	A settable name for this box. This name defaults to an ASCII representation of the base MAC address of the box, but may be set to a user-friendly display string by a management application.
hpicfStackAgentTable	1.3.6.1.4.1.11.2.14.11.1.5.2		not-accessible	This table provides a list of SNMP agent cards in the stack that are capable of managing the stack. Note that this table is redundant, since this information is available in the Entity MIB, but is provided for the convenience of management applications, so that they are not required to scan the entire entPhysicalTable to determine what agent cards are present.
hpicfStackAgentEntry	1.3.6.1.4.1.11.2.14.11.1.5.2.1		not-accessible	An entry in the hpicfStackAgentTable representing a single agent card. This table is indexed by the value of entPhysicalIndex that corresponds to the row in the entPhysicalTable for this agent card.
OCT hpicfStackAgentBoxId	1.3.6.1.4.1.11.2.14.11.1.5.2.1.1	OCTET STRING	read-only	The value of hpicfStackBoxId for the box containing this agent card. Note that this object is redundant since containment information is available in the Entity MIB, but is provided for the convenience of management applications (and so that there would be at least one accessible column in this table).
I32 hpicfStackActiveAgentEx	1.3.6.1.4.1.11.2.14.11.1.5.3	Integer32	read-write	The value of entPhysicalIndex for the agent that is currently managing this stack. A set to this value will also set hpicfStackAgentForced to 'true'. Note that setting this object to a value different from the current value will cause this agent to reset. After reset, the current agent will no longer be active, because the new agent will take over.
T/F hpicfStackAgentForced	1.3.6.1.4.1.11.2.14.11.1.5.4	TruthValue	read-only	A value of 'true' indicates that the current active agent card has been chosen by a management action as the active agent. This management action may have been performed through a console user interface command, or by setting the hpicfStackActiveAgent object. The reason for this is to allow the network administrator to prevent an added redundant agent from taking over when there is a configured agent card in the stack.
