HUAWEI-LAG-MIB

Description: Huawei Link Aggregation Group MIB for managing Ethernet trunk groups, member port assignments, load balancing, and aggregate interface statistics.

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-LAG-MIB is a Huawei-specific SNMP module, described internally as an "LACP extend MIB," for managing Ethernet Link Aggregation Groups (trunk groups) on Huawei switches and routers. It exposes objects covering trunk group membership, individual member port assignment, load-balancing algorithm configuration, and aggregate-interface traffic statistics. From a monitoring standpoint it lets an operator confirm the software/protocol state of LACP-negotiated trunks and the hardware-level up/down status of each member port, which is critical for detecting a failed or flapping physical link that has silently reduced trunk capacity. It extends the standard IEEE 802.3ad/802.1AX LACP model with Huawei-specific enhancements rather than replacing it. It is typically deployed on Huawei campus and data-center switches where multiple physical ports are bonded into a single logical high-bandwidth, redundant link, and administrators can download the HUAWEI-LAG-MIB file to load it into their MIB browser.

No sample objects were listed in the source, but a realistic scenario would involve polling the trunk group table to enumerate active member ports and comparing the configured count against the operationally up count. A mismatch would reveal a member port that has gone down or been administratively removed, silently degrading the aggregate bandwidth without taking the whole trunk offline.
