Description: H3C MIB for DHCPv4 server and relay management including address pools, leases, and 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 H3C-DHCP4-MIB?

H3C-DHCP4-MIB is an H3C-specific MIB for managing and monitoring the DHCPv4 server and relay features on H3C network devices. It exposes server-side configuration flags (broadcast behavior, BOOTP compatibility, option-82 support, ping-before-offer settings) alongside operational counters for DHCP message activity, and separate relay configuration/statistics groups. This is primarily a software-service monitoring MIB: it lets an operator confirm the DHCP server process is enabled and behaving as configured, and watch counters such as bad-packet counts, BOOTP request counts, and DHCPDISCOVER/REQUEST/DECLINE counts to spot address-pool exhaustion, misbehaving clients, or a failing server process. It has no stated formal dependency on other MIBs, being a self-contained H3C proprietary module for this feature. It is typically deployed on H3C routers/switches acting as DHCP servers or relay agents in enterprise or service-provider access networks. Engineers can download the H3C-DHCP4-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-DHCP4-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 routers and switches (DHCPv4 server/relay role)

Monitoring Examples

An admin polls h3cDhcpServer2Enabled to confirm the DHCPv4 server is active, then watches h3cDhcpServer2DiscoverNum, h3cDhcpServer2RequestNum, and h3cDhcpServer2DeclineNum to gauge lease-negotiation volume and detect clients repeatedly declining offered addresses (often an address-pool conflict). A rising h3cDhcpServer2BadNum alongside h3cDhcpServer2BootpRequestNum can indicate malformed or unexpected BOOTP traffic hitting the server. Checking h3cDhcpServer2PingNumber/PingTimeout settings helps confirm the server's duplicate-address-detection ping behavior before lease assignment.

What Can Be Monitored

  • DHCP server enabled/config state
  • DHCP discover/request/decline counts
  • bad/malformed packet counts
  • BOOTP request handling
  • ping-before-offer configuration
  • relay configuration and statistics
