Description: Defines managed objects for Dynamic Host Configuration Protocol (DHCP) server software, providing SNMP access to DHCP server configuration and lease information.
IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring DHCP-MIB with a free 30-day trial of IPNetwork Monitor.
What Is DHCP-MIB?
This module defines managed objects for DHCP (Dynamic Host Configuration Protocol) server software, providing SNMP access to DHCP server configuration and lease information; it follows the common industry pattern for DHCP server MIBs rather than being tied to one specific hardware vendor. It exposes two broad categories of data: server-side configuration parameters (scopes, options, policy settings) and dynamic operational state such as active address leases. As a monitoring module its central use is verifying the software/service health of the DHCP server process itself -- confirming it is issuing and renewing leases correctly and has not exhausted its address pool -- rather than reporting physical hardware sensors. It is typically layered on top of standard IP addressing concepts (e.g. IP-MIB) since lease data is fundamentally about IP address assignment. It is deployed on routers, firewalls, or dedicated appliances/servers that provide DHCP service to a LAN or branch network, monitored via an SNMP-based NMS that polls this DHCP MIB to track lease and scope health across the network.
IPNetwork Monitor allows you to monitor SNMP objects defined in DHCP-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
- router, firewall, or server running DHCP server software (vendor-neutral MIB pattern)
Monitoring Examples
No specific object or table names were included in the source excerpt for this module; based on its description, an administrator would typically poll DHCP server configuration objects to confirm scope/pool settings are as expected, and lease-information objects to check how many addresses are currently leased out -- a pool nearing exhaustion (few free addresses remaining) would be a clear signal to expand the scope before new clients start failing to obtain an address.
What Can Be Monitored
- DHCP server configuration / scope settings
- active DHCP lease information
- address pool utilization
