Description: Monitors H3C firewall session tables, policy hit counters, and zone-based security statistics.

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-FIREWALL-MIB?

The A3COM-HUAWEI-FIREWALL-MIB is an H3C-specific MIB for managing firewall products, exposing session-table capacity and utilization, policy-hit statistics, and zone-based security counters. It provides both configuration data such as maximum connection capacity and firewall specifications, and real-time performance/fault data such as current active connections and global statistics. Its central monitoring use case is tracking software/hardware load on the firewall's session table, comparing h3cFWConnNumCurr against h3cFWMaxConnNum to reveal whether the device is approaching session-table exhaustion, effectively a capacity/health check on the firewall's inspection engine. As a firewall-specific MIB it has no strong formal dependency on other standard MIBs, though it complements standard interface/TCP counters. It is deployed on H3C security appliances and firewall modules protecting data-center or campus network perimeters, where A3COM-HUAWEI-FIREWALL-MIB SNMP monitoring provides an early warning of session-table exhaustion.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-FIREWALL-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 firewall appliance/security module

Monitoring Examples

Polling h3cFWConnNumCurr alongside h3cFWMaxConnNum lets an admin graph session-table utilization over time and alert before the firewall hits its connection ceiling, a condition that causes silent drops of new sessions during a traffic surge or SYN flood. h3cFirewallGlobalStats provides aggregate counters useful for confirming security policies are actively filtering traffic rather than passing it unfiltered.

What Can Be Monitored

  • current vs maximum concurrent sessions
  • global firewall statistics/policy hits
  • firewall hardware specifications
  • zone-based security counters

How to Use in IPNetwork Monitor

Example using h3cFWConnNumCurr OID:

Select an H3C firewall 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 h3cFWConnNumCurr into the Find box to locate it in the OID tree, then select it and click OK. The number of connections that currently exist. 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 Gauge32-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.
