Description: Manages DHCP server address pools, lease bindings, and allocation statistics on H3C devices.

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-DHCP-SERVER-MIB?

A3COM-HUAWEI-DHCP-SERVER-MIB is an H3C (Hangzhou H3C Tech. Co., Ltd.) proprietary MIB managing the built-in DHCP server on H3C routers/switches. Its objects cover per-pool IP-usage percentage, request/successful-request counts, average/max IP-use warning thresholds, an allocate threshold, pool name, a global-pool table (name, row status), a pool-configuration table (type, network/mask, host IP/mask/hardware address, undo-config flag, address range start/end), and a lease-parameter table (lease day). As a configuration/performance MIB it lets an administrator confirm DHCP pool address-range utilization and get alerted before a pool runs out of addresses. It is deployed on H3C (3Com-Huawei) routers/switches. Engineers can download the A3COM-HUAWEI-DHCP-SERVER-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-DHCP-SERVER-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-Huawei) routers/switches

Monitoring Examples

An administrator monitors h3cDHCPServerIPPoolUsage against h3cDHCPServerMaxIpUseThreshold to catch a DHCP pool approaching exhaustion on an H3C router.

What Can Be Monitored

DHCP pool address-range utilization

How to Use in IPNetwork Monitor

Example using h3cDHCPServerReqTimes OID:

Select an H3C router or switch 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 h3cDHCPServerReqTimes into the Find box to locate it in the OID tree, then select it and click OK. It reports the number of requests received by the DHCP server. 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.
