Description: Manages syslog configuration on H3C/3Com devices, providing log source definitions, severity filter settings, and remote syslog server configuration.

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-SYSLOG-MIB?

A3COM-HUAWEI-SYSLOG-MIB is a vendor-specific MIB used on H3C and 3Com network switches and routers (products of the joint 3Com-Huawei H3C venture) to manage the device's system logging subsystem. It exposes configuration data covering log channels (console, monitor, SNMP, log buffer), severity filtering, the number of configured log hosts, and buffer sizing for stored log and trap messages. Because syslog is the primary mechanism for surfacing software and hardware fault events, this MIB is directly useful for monitoring device health: administrators can check whether logging is enabled, how full the internal log buffer is, and inspect buffered log entries for hardware faults, link flaps, or configuration errors without console access. It is a standalone vendor MIB with no strong dependency on other IETF standards beyond the general SNMP/SMIv2 framework. Typical deployment context is centralized network monitoring of H3C/3Com campus or data-center switches, where an NMS polls or configures remote syslog forwarding for compliance and troubleshooting. Engineers can download the A3COM-HUAWEI-SYSLOG-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-SYSLOG-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 switch/router

Monitoring Examples

An administrator would poll h3cSyslogState to confirm logging is active and compare h3cSyslogLogbufferSize against h3cSyslogMaxLogbufferSize to see how close the in-memory log buffer is to overflowing. Walking h3cSyslogLogbufferTable (h3cSyslogLogbufferEntry) retrieves the actual buffered log messages, useful for spotting repeated hardware error entries such as power or interface faults. Setting h3cSyslogSnmpChannel or h3cSyslogConsoleChannel lets an operator control which log severities are forwarded to a monitoring station.

What Can Be Monitored

syslog service state
log buffer utilization
buffered log entries
configured log host count
channel severity filtering
trap buffer size

How to Use in IPNetwork Monitor

Example using h3cLogbufferOverwrittenMessages OID:

Select an H3C/3Com switch and router 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 h3cLogbufferOverwrittenMessages into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of log messages overwritten in logbuffer. 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 a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
