Description: HP ICF SNMP MIB for UDP broadcast forwarding (IP helper) configuration directing broadcast packets to servers 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-UDP-FORWARD?

This MIB is part of HP's Industry-standard Command-line Framework (ICF) for HP ProCurve/Aruba networking switches. It exposes configuration data for UDP broadcast forwarding (IP helper), a feature that relays DHCP and other broadcast requests from one VLAN to servers on another subnet. Its categories of data include forwarding server configuration (per-VLAN server address/port entries), admin status, and fault-related counters for DHCP relay activity, letting administrators monitor the software health of the relay feature by watching discard versus forward counts. It fits alongside HP's broader ICF MIB family and standard VLAN/IP addressing conventions rather than depending on any single external MIB. It is typically deployed in enterprise or campus networks, where administrators can download the HP-ICF-UDP-FORWARD MIB to monitor DHCP relay across multiple VLANs on HP ProCurve/Aruba switches.

IPNetwork Monitor allows you to monitor SNMP objects defined in HP-ICF-UDP-FORWARD. 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 networking switch

Monitoring Examples

An admin polls hpicfUdpFwdServersTable / hpicfUdpFwdServersEntry to see configured forwarding server addresses (hpicfUdpFwdServerAddress, hpicfUdpFwdPortNumber) per hpicfUdpFwdVlanId, and checks hpicfUdpBcastFwdAdminStatus to confirm forwarding is enabled. Rising hpicfUdpFwdDhcpRelayClientDiscards or hpicfUdpFwdDhcpRelayServerDiscards signals DHCP relay failures such as a misconfigured or unreachable server, while hpicfUdpFwdDhcpRelayClientForwards trending toward zero suggests broadcast forwarding has stopped working.

What Can Be Monitored

UDP broadcast forwarding admin status
configured forwarding servers per VLAN
DHCP relay client discards
DHCP relay client forwards
DHCP relay server discards

How to Use in IPNetwork Monitor

Example using hpicfUdpFwdDhcpRelayClientDiscards OID:

Select an HP ProCurve/Aruba switch (UDP broadcast/DHCP relay forwarding) 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 hpicfUdpFwdDhcpRelayClientDiscards into the Find box to locate it in the OID tree, then select it and click OK. The number of DHCP client packets discarded by the relay agent for any reason. 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.
