Category: Network Monitoring (RMON), Vendor: H3C/HH3C
Description: Extends RMON with H3C/3Com switch-level monitoring capabilities, providing enhanced statistics and history for switched LAN traffic analysis.
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-LswSMON-MIB?
A3COM-HUAWEI-LswSMON-MIB extends the standard RMON framework with H3C/3Com switch-specific "SMON" (Switch Monitor) capabilities, adding enhanced statistics and history collection for switched LAN and VLAN traffic beyond what base RMON provides. Its exposed objects, notably hwdot1qVlanStatNumber, indicate the number of VLAN-based statistics entries being tracked, alongside container objects (hwSmonExtend, smonExtendObject) that group the vendor's extended monitoring data. This supports monitoring of switch traffic-plane performance: per-VLAN traffic statistics let an operator see utilization and error trends on a per-VLAN basis, useful for spotting a misbehaving VLAN or an overloaded segment, rather than physical hardware faults. Dependency: it explicitly builds on and extends the IETF RMON MIB and its SMON extensions, adding vendor-specific VLAN statistics not present in the base standards. Deployment is on H3C/3Com LAN switches where per-VLAN traffic visibility is needed for capacity planning or troubleshooting, typically at the distribution or core layer, and administrators typically begin with an A3COM-HUAWEI-LswSMON-MIB download to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-LswSMON-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/3Com LAN switches
Monitoring Examples
An admin would poll hwdot1qVlanStatNumber to see how many VLAN statistics entries are currently being collected, then drill into the underlying per-VLAN counters referenced under smonExtendObject to compare traffic volume across VLANs sharing a trunk. A VLAN whose statistics show a disproportionate share of the trunk's total traffic or error count would point to a broadcast storm or a misconfigured device flooding that VLAN.
What Can Be Monitored
- number of VLAN statistics entries tracked
- per-VLAN traffic statistics
- extended switch-monitor (SMON) statistics
