Description: LeftHand Networks MIB for managing network interface settings on LeftHand NUS iSCSI SAN storage appliances.

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 LEFTHAND-NETWORKS-NUS-COMMON-NETWORK-MIB?

LEFTHAND-NETWORKS-NUS-COMMON-NETWORK-MIB is an HP (StorageWorks Division, LeftHand Networks heritage) proprietary MIB reporting network-interface configuration shared across HP StorageWorks (LeftHand) NSM (Network Storage Module) SAN storage nodes. Its device table, keyed by index, records device name, IP address, mask, default gateway, mode, and status, with an overall device count. As a configuration/status MIB it lets an administrator confirm a storage node's network interface addressing and operational mode. It is deployed on HP StorageWorks (LeftHand Networks) SAN storage nodes. Engineers can download the LEFTHAND-NETWORKS-NUS-COMMON-NETWORK-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in LEFTHAND-NETWORKS-NUS-COMMON-NETWORK-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 StorageWorks (LeftHand Networks) SAN storage nodes

Monitoring Examples

An administrator checks networkDeviceIpAddress and networkDeviceStatus to confirm a LeftHand SAN storage node's network interface is correctly addressed and up.

How to Use in IPNetwork Monitor

Example using networkDeviceCount OID:

Select an HP StorageWorks (LeftHand Networks) SAN storage node (network interfaces) 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 networkDeviceCount into the Find box to locate it in the OID tree, then select it and click OK. It reports number of network devices. 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 INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the count changes from its expected baseline, since that would indicate the underlying set of items changed unexpectedly. Click Finish to create the monitor; you can adjust any parameter later.
