Category: Device Management, Vendor: H3C/HH3C
Description: Provides H3C/3Com-specific extensions to the SNMP framework, including community configuration, target host management, and notification control objects.
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 A3COM-HUAWEI-SNMP-EXT-MIB?
A3COM-HUAWEI-SNMP-EXT-MIB is a joint 3Com/Huawei (H3C) vendor MIB that provides extensions to the standard SNMP management framework itself, adding objects for community string configuration, target host (trap/notification destination) management, and finer-grained notification control on H3C/3Com network devices. It exposes SNMP-agent configuration data -- community definitions, notification target hosts, and related control objects -- rather than device hardware or traffic telemetry; its three top-level groupings separate scalar configuration objects, tabular objects, and notifications. In monitoring terms it is used to confirm the SNMP management plane itself is correctly configured (e.g., which hosts receive traps, which communities are valid) rather than to report on CPU, memory, temperature, or fan status of the device. It directly extends and depends on the standard SNMPv2 framework MIBs (SNMP-COMMUNITY-MIB, SNMP-TARGET-MIB, SNMP-NOTIFICATION-MIB), adding vendor-specific objects alongside them. It is typically deployed on H3C and 3Com-heritage switches and routers where administrators need finer control over SNMP notification delivery than the standard framework MIBs alone provide, and they typically load the module into an A3COM-HUAWEI-SNMP-EXT-MIB MIB Browser to review these settings directly.
IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-SNMP-EXT-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
- H3C switch/router
- 3Com-heritage network switch
Monitoring Examples
An administrator would inspect the h3cSnmpExtTables entries (analogous to community and target-host tables) alongside h3cSnmpExtScalarObjects to confirm which management stations are configured to receive traps and with which community strings, and would monitor h3cSnmpExtNotifications definitions to know what notification types the extension can emit. Discovering that an expected target host is missing from the extended target table would explain why a management station stopped receiving traps from the device. Because detailed column names were not provided, this description stays at the table/object-group level shown in the sample objects.
What Can Be Monitored
- SNMP community configuration
- notification target host configuration
- SNMP extension notification settings
