Description: HP ServerNet (Foundry-heritage) SNMP MIB for IP layer management including routing tables and interface addresses on HP SN devices.

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-SN-IP-MIB?

HP-SN-IP-MIB is a Foundry-heritage SNMP MIB for managing the IP layer on HP ServerNet (SN) class routing devices, covering routing behavior, ARP handling, BOOTP relay, and various IP protocol feature toggles. It exposes configuration and operational objects such as route-only mode, ARP cache age timers, IRDP router discovery, IP load sharing, proxy ARP, RARP, and IP TTL settings, along with operational actions like clearing the ARP cache, IP cache, or IP route table. From a monitoring perspective it confirms the device's IP forwarding/software configuration state matches intended policy — for example whether proxy ARP or load sharing is enabled where it shouldn't be — and supports troubleshooting stale routing/ARP behavior by triggering cache clears. It builds on standard IP/ARP concepts found in IETF IP-MIB conventions, adapted into HP's proprietary Foundry-heritage numbering. It is deployed on HP SN-series routing switches in enterprise and service-provider network cores/edges, and administrators can download the HP-SN-IP-MIB file to load it into their MIB browser for IP layer monitoring.

IPNetwork Monitor allows you to monitor SNMP objects defined in HP-SN-IP-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 SN-series (Foundry-heritage) routing switch

Monitoring Examples

An admin troubleshooting stale routing behavior might set snRtClearIpRoute or snRtClearArpCache to force the device to rebuild its tables, then re-poll snRtIpProxyArp and snRtIpLoadShare to confirm whether proxy ARP or load-sharing settings — which could be causing asymmetric routing — are enabled as expected; snRtArpAge reveals whether ARP entries are timing out faster than intended, causing repeated ARP storms.

What Can Be Monitored

  • IP route-only mode
  • ARP cache age
  • proxy ARP / RARP status
  • IP load sharing
  • IRDP router discovery
  • BOOTP relay configuration
