Description: HP ICF SNMP MIB for managing the DHCP client configuration and lease status on HP ProCurve switch management interfaces.

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-DHCPCLIENT-MIB?

HP-ICF-DHCPCLIENT-MIB is an HP proprietary MIB for managing the DHCP client on an HP ICF device's management interface, covering configuration of DHCP-based IP address acquisition and the resulting lease status. It is expected to expose objects for enabling or disabling DHCP client mode and for viewing the obtained IP address, lease time, and related client state - primarily configuration and software status data. Its monitoring value lies in confirming that the device successfully obtained or renewed its management IP address via DHCP, and in detecting lease expiration or DHCP failures that could cause loss of management connectivity. It relates to the general DHCP concepts of RFC 2131 though implemented as an HP-proprietary client-status module. It is deployed on HP ProCurve/Aruba switches whose management interface is configured for DHCP rather than a static address. Engineers can download the HP-ICF-DHCPCLIENT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HP-ICF-DHCPCLIENT-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 switch
HP Aruba (ICF-based) switch

Monitoring Examples

No specific object or table names were captured in the sampled data for this module, so a concrete OID-level example cannot be given; based on its purpose, an administrator would poll the DHCP client's lease and address status to confirm the switch's management IP address is current, with an unexpectedly expired or failed lease explaining a sudden loss of SNMP/management reachability to the device.

What Can Be Monitored

DHCP client enable/disable state
assigned management IP address
lease time/status
DHCP client operational state

How to Use in IPNetwork Monitor

Example using hpicfDhcpClientPktTx OID:

Select an HP ProCurve/Aruba switch (management-interface DHCP client) 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 hpicfDhcpClientPktTx 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. It reports the number of DHCP packets transmitted. 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.

OIDs

OID symbolic	OID numeric	Type	Access	Description
hpicfDhcpClient	1.3.6.1.4.1.11.2.14.11.5.1.57			This MIB module contains HP proprietary objects for managing the DHCP Client.
hpicfDhcpClientOptions	1.3.6.1.4.1.11.2.14.11.5.1.57.1
INT hpicfDhcpClientVendorSpecOptionStatus	1.3.6.1.4.1.11.2.14.11.5.1.57.1.1	INTEGER	read-write	This flag indicates whether DHCP vendor specific configurations are enabled for this interface or not. Setting this flag to 'enabled' (the default) results in sending 'Vendor Class Identifier'(VCI) to DHCP server and requesting vendor specific configurations from DHCP servers for this interface. Refer to RFC 2132 for more details. Setting this flag to 'disabled' results in not sending VCI to DHCP server and not requesting vendor specific configurations from DHCP servers.
INT hpicfDhcpClientHostNameOption	1.3.6.1.4.1.11.2.14.11.5.1.57.1.2	INTEGER	read-write	This object enables/disables DHCP option 12 that allows for sending the system's hostname in DHCP packets. By default this object is set to be disabled. Setting this flag to 'enabled' results in the inclusion of system hostname in DHCP packets.
INT hpicfDhcpClientImageFileUpdate	1.3.6.1.4.1.11.2.14.11.5.1.57.1.3	INTEGER	read-write	This object facilitates enabling or disabling of the image file update feature through DHCP. Setting this object to 1 enables this feature and setting it to 2 disables this feature. This MIB object can be set to 1 only if hpicfDhcpClientVendorSpecOptionStatus has already been set to 1. By default, hpicfDhcpClientImageFileUpdate is set to 1. When this feature is enabled, the Auto-TFTP settings will be disabled.
hpicfDhcpClientintfTable	1.3.6.1.4.1.11.2.14.11.5.1.57.1.4		not-accessible	DHCP client's interface level configuration table. Common to both v4 and v6 DHCP clients.
hpicfDhcpClientintfEntry	1.3.6.1.4.1.11.2.14.11.5.1.57.1.4.1		not-accessible	A row in hpicfDhcpClientintfTable.
INT hpicfDhcpClientAuthType	1.3.6.1.4.1.11.2.14.11.5.1.57.1.4.1.1	INTEGER	read-write	The authentication type specified for an interface.
STR hpicfDhcpClientKeyChain	1.3.6.1.4.1.11.2.14.11.5.1.57.1.4.1.2	DisplayString	read-write	KMS chain name specified for an interface.
hpicfDhcpClientStatisticsTable	1.3.6.1.4.1.11.2.14.11.5.1.57.1.5		not-accessible	DHCP client's interface level statistics.
