HUAWEI-LswMix-MIB

Description: Huawei MIB covering a mix of LAN switch features, including port security, storm control, and general system configuration objects.

HUAWEI-LswMix-MIB is a Huawei LAN switch MIB that bundles miscellaneous, chassis-level management objects for Huawei switches that don't fit into a single dedicated feature MIB, including main processing unit (MPU) switchover tracking, slot/board inventory, and crossbar fabric status. Its objects span hardware inventory and status, board presence and status per slot, crossbar switch fabric health, as well as system-level events like MPU active/standby switchovers. This module is explicitly hardware-status oriented: it reports the physical board status of each slot via hwLswXSlotTable/hwLswXSlotEntry, the health of the main control board via hwLswMainCardBoardStatus, the crossbar switching fabric's condition via hwLswCrossBarStatus, and records of when and how often the MPU has switched over via hwLswLastSwitchDate/hwLswLastSwitchTime and hwLswMpuSwitchsNum/hwLswMpuSwitch, all central to detecting hardware faults or unplanned failovers in modular chassis switches. It is a Huawei-proprietary module without direct standards-based dependency, layered on top of the switch's own chassis management architecture. It is typically deployed on modular, dual-MPU Huawei switches in data center or core network roles where high availability and hardware redundancy are important, and the HUAWEI-LswMix-MIB download is available to administrators who want to load it into their MIB browser.

An administrator would poll hwLswMpuSwitchsNum and hwLswLastSwitchDate/hwLswLastSwitchTime to track how often and when the active MPU has failed over to standby, and walk hwLswXSlotTable/hwLswXSlotEntry to confirm every populated slot reports a healthy hwLswMainCardBoardStatus. An unexpected increment in the switchover counter or a slot reporting a fault status in hwLswCrossBarStatus would indicate a hardware failure or instability in the chassis's redundancy fabric.
