Description: Monitors DHCP relay agent configuration and forwarded-packet statistics on H3C network 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-DHCPR-MIB?
A3COM-HUAWEI-DHCPR-MIB is an H3C/3Com proprietary SNMP module for managing the DHCP Relay Agent feature on H3C switches and routers, complementing IETF DHCP-related work rather than replacing it. It is expected to expose relay-agent configuration, such as which interfaces relay DHCP requests and configured server addresses, along with counters for forwarded and dropped DHCP packets. As a configuration/statistics MIB it supports monitoring of the DHCP relay software function's operational health, since forwarded/dropped packet counts serve as a proxy for whether the relay service itself is functioning correctly, distinct from monitoring underlying router hardware. It would typically be used alongside interface MIBs and the vendor's IP-address MIBs since DHCP relay operates on a per-interface basis. Typical deployment is on H3C access or aggregation switches and routers acting as DHCP relay agents between client VLANs and centralized DHCP servers, where A3COM-HUAWEI-DHCPR-MIB SNMP monitoring helps confirm the relay service remains operational.
IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-DHCPR-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 switches and routers
Monitoring Examples
No specific object or table names were available in the sampled source for this module, so a concrete OID-level polling scenario is not given here to avoid inventing identifiers. In practice an admin would look for relay-agent enable/disable status per interface and forwarded/dropped packet counters, and a spike in dropped DHCP requests would typically indicate a relay misconfiguration or an unreachable DHCP server.
What Can Be Monitored
- DHCP relay agent enable status per interface
- forwarded DHCP packet counts
- dropped DHCP packet counts
