Description: Manages directed IP broadcast forwarding policies and helper-address configuration 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-IP-BROADCAST-MIB?
The A3COM-HUAWEI-IP-BROADCAST-MIB is an H3C-specific configuration MIB describing directed IP broadcast forwarding policy and UDP helper-address settings, which control whether and where broadcast packets such as DHCP or NetBIOS requests are relayed across router interfaces. It is primarily a configuration-oriented module rather than a counters module, exposing per-interface broadcast-forwarding enable/disable state and configured helper (relay) addresses. Its monitoring value lies in confirming the software/configuration status of broadcast relay behavior, verifying that helper addresses are correctly configured on interfaces expected to forward DHCP or other broadcast-based service requests, which if misconfigured causes client provisioning failures. Vendor documentation notes some objects apply only to specific H3C product lines, implying dependency on base IP-MIB concepts rather than a formal external MIB. It is deployed on H3C routers acting as DHCP relay/helper points at the edge of routed IP subnets. Engineers can download the A3COM-HUAWEI-IP-BROADCAST-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-IP-BROADCAST-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 (Layer 3 edge device)
Monitoring Examples
Since no specific object names are exposed in the sample set, an admin would typically poll the module's per-interface broadcast-forwarding table to confirm directed-broadcast forwarding is disabled on internet-facing interfaces (a common security hardening check) while enabled with the correct helper address on interfaces serving DHCP clients. A subnet where clients cannot obtain DHCP leases would prompt a check of the helper-address entry for that interface.
What Can Be Monitored
- directed broadcast forwarding enable/disable per interface
- configured helper/relay addresses
- broadcast forwarding policy
