Category: Protocol: DHCP, Vendor: H3C/HH3C

Description: Manages DHCPv4 server address pools, leases, and statistics on H3C routing platforms.

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 HH3C-DHCP-SERVER-MIB?

This MIB manages the DHCPv4 server function on H3C (Hangzhou Huawei-3Com/New H3C) routing and switching platforms, part of H3C's private enterprise MIB tree for its IP services feature set. It exposes DHCP address pool configuration, active lease information, and server-level statistics. Its monitoring emphasis is on software/service status: whether the DHCP server process is enabled and functioning, how much of each address pool is currently leased out, and whether lease allocation is succeeding, which is the practical health signal for a device providing DHCP to a LAN. It functions as a private extension alongside the standard DHCP protocol (RFC 2131) rather than depending on another SNMP MIB. It is deployed on H3C routers and switches acting as the DHCP server for one or more LAN segments in enterprise or campus networks, making HH3C-DHCP-SERVER-MIB SNMP monitoring a practical way to track pool utilization and lease health on those platforms.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-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 router
H3C Layer 3 switch

Monitoring Examples

No specific object or table names were provided in the sample for this MIB, so exact identifiers can't be cited here. Conceptually, an admin would poll DHCP address pool utilization and active lease counts to detect a pool nearing exhaustion, and check the DHCP server's enable/service status to confirm it is actively responding to client requests. A pool showing consistently high utilization with rising allocation failures would reveal that the configured address range is too small for the client population.

What Can Be Monitored

DHCP address pool utilization
active lease count
DHCP server enable/service status
lease allocation failures

How to Use in IPNetwork Monitor

Example using hh3cDHCPServerReqTimes OID:

Select an H3C router/Layer 3 switch (DHCPv4 server) 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 hh3cDHCPServerReqTimes 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.
