H3C-IP-BROADCAST-MIB

Description: H3C MIB for IP directed broadcast management controlling forwarding of subnet-directed broadcast packets.

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.

H3C-IP-BROADCAST-MIB is a vendor-specific MIB from H3C (Hewlett-Packard/New H3C's networking division, a Cisco-comparable enterprise switch/router vendor) for controlling IP directed-broadcast forwarding behavior, i.e. whether packets addressed to a subnet's broadcast address are relayed onto that subnet. Without captured sample objects, its scope per the module description is configuration of this broadcast-forwarding feature, which may vary by product line. Its monitoring relevance is centered on software configuration state -- confirming directed-broadcast forwarding is enabled or disabled as intended on a given interface, since misconfiguration here has both operational (smurf-attack amplification) and security implications. It is a small, self-contained feature MIB likely layered on top of H3C's IP interface configuration framework rather than any IETF standard. It would be deployed on H3C (H3C/HP Comware) routers and switches in enterprise and carrier networks. Engineers can download the H3C-IP-BROADCAST-MIB file directly to load it into their MIB browser.

No sample objects were captured for this MIB; based on the module description, an administrator would poll a per-interface object indicating whether IP directed-broadcast forwarding is enabled, to confirm the security posture of an interface and catch a device where the feature was inadvertently left on, which could allow it to participate in broadcast-based amplification traffic.
