Description: Manages Layer 2 switching features on Compaq/HP ProCurve network 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 COMPAQ-L2MGMT-MIB?

COMPAQ-L2MGMT-MIB is a vendor MIB for Compaq (later HP ProCurve) network switches that manages Layer 2 switching features, specifically port trunking/link aggregation and IGMP-related multicast functions. It is primarily a configuration MIB, exposing objects that let an administrator define and query trunk group membership and IGMP snooping/multicast behavior on the switch. For status monitoring, the trunk and IGMP state it exposes is useful for confirming that link aggregation groups are correctly formed and that multicast traffic is being managed as expected, which speaks to the switch's Layer 2 forwarding software health rather than physical hardware sensors. It is a Compaq-specific structure of management information, predating full alignment with later IETF standards like the Bridge MIB or IGMP-STD-MIB. It is deployed on Compaq/HP ProCurve switches in networks that rely on trunked uplinks and IGMP snooping for multicast efficiency, making COMPAQ-L2MGMT-MIB SNMP monitoring useful for confirming trunk formation and multicast forwarding behavior.

IPNetwork Monitor allows you to monitor SNMP objects defined in COMPAQ-L2MGMT-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.

Compaq/HP ProCurve network switches

Monitoring Examples

An administrator would check the trunk configuration objects to confirm that member ports are correctly grouped into a link-aggregation trunk and that the trunk is passing traffic as expected, since a misconfigured or partially-formed trunk can cause asymmetric or dropped traffic. The IGMP-related objects would be checked when multicast video or similar traffic isn't reaching expected ports, to confirm IGMP snooping is enabled and functioning on the relevant VLAN.
