Description: LeftHand Networks MIB for managing security and access control policies on LeftHand NUS iSCSI 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-SECURITY-MIB?

LEFTHAND-NETWORKS-NUS-COMMON-SECURITY-MIB is a LeftHand Networks vendor MIB for managing security and access control policies on LeftHand Network Unified Storage (NUS) iSCSI storage appliances. It exposes user and group account management tables, including counts, names, descriptions, and row-status controls for provisioning security principals on the storage system. Its role is primarily configuration/administrative status monitoring, tracking how many local users and groups exist and their provisioning state (via row status), rather than classic hardware telemetry, though it indirectly reflects the software-level access-control health of the storage appliance. No explicit dependency on other MIBs is evident from the available description, though the row-status pattern follows standard SNMPv2 SMI conventions. It is typically deployed by storage administrators managing local authentication and authorization on LeftHand NUS iSCSI SAN appliances. Engineers can download the LEFTHAND-NETWORKS-NUS-COMMON-SECURITY-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in LEFTHAND-NETWORKS-NUS-COMMON-SECURITY-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

LeftHand Networks NUS iSCSI storage appliance

Monitoring Examples

An administrator would poll secUserCount and walk secUserTable (via secUserEntry, indexed by secUserIndex) to check secUserName and secUserRowStatus, detecting whether a user account is active, being created, or has become inconsistent, which could indicate an access-control misconfiguration. Similarly, secGroupCount and secGroupTable/secGroupEntry (indexed by secGroupIndex) would be checked to confirm expected group memberships exist on the storage appliance, revealing unauthorized or missing security groups.

What Can Be Monitored

local user account count
user account name and description
user account provisioning status
security group count
group provisioning status

How to Use in IPNetwork Monitor

Example using secUserCount OID:

Select a LeftHand Networks NUS iSCSI storage appliance (users/groups) 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 secUserCount into the Find box to locate it in the OID tree, then select it and click OK. It reports the number of users in the NUS. 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.
