HUAWEI-PORTBLOCK-MIB

Description: Huawei port blocking MIB for managing port access restriction policies to limit unknown unicast and multicast flooding.

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.

HUAWEI-PORTBLOCK-MIB is a Huawei switch MIB implementing the port block feature, which restricts flooding of unknown unicast and multicast traffic out of specified switch ports to control broadcast/flood storms and limit information leakage. It exposes configuration objects that enable or disable blocking of unknown unicast/multicast flooding on a per-port basis. For monitoring, it is used to confirm the software/configuration state of this traffic-control feature per port, verifying that block settings match the intended security/traffic-isolation policy, rather than exposing hardware sensors or performance counters. It is a Huawei-proprietary feature MIB without a direct IETF standard equivalent, complementing standard bridge/storm-control mechanisms. It is deployed on Huawei LAN switches in environments where limiting unnecessary flooded traffic between ports is a security or performance requirement, and network engineers can download the HUAWEI-PORTBLOCK-MIB file directly to load it into their MIB browser.

No sample objects were provided, but a typical use would be polling the per-port block-enable objects to confirm unknown-unicast/multicast flooding is disabled on ports facing untrusted segments, catching any port where the block setting was inadvertently reverted.
