ZYXEL-LOAD-SHARING-MIB

Description: Manages ZyXEL load sharing configuration across aggregated links for traffic distribution balancing.

Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

ZYXEL-LOAD-SHARING-MIB is a ZyXEL private enterprise MIB governing load-sharing (link aggregation traffic distribution) configuration on ZyXEL switches, placing it in the switching/link-aggregation configuration category. It exposes settings that control how traffic is balanced across the physical members of an aggregated link, such as the hashing algorithm or distribution mode used, rather than hardware sensors or fault logs. Its main value for device monitoring is confirming that the configured load-sharing algorithm and aggregate group membership match what was provisioned, and, where counters are exposed, that traffic is actually being spread across member ports rather than piling onto one link. It relies on the switch's link-aggregation/trunk group definitions, commonly aligned with IEEE 802.3ad/802.1AX LACP, as the object it configures. It is typically deployed on ZyXEL access and aggregation switches that use link aggregation groups between switches or toward uplinks for redundancy and bandwidth scaling, with configuration exposed through the ZYXEL-LOAD-SHARING-MIB MIB.

An administrator would check the load-sharing algorithm setting for a given aggregated link group to confirm it matches the intended hashing method, then compare per-member-port traffic levels to verify the load is actually balanced across the trunk's physical links. If one member port consistently carries far more traffic than its peers despite an even hashing algorithm being configured, it could indicate a flawed traffic pattern, a failed link falling back to another, or a misconfigured aggregation group. Because ZYXEL-LOAD-SHARING-MIB primarily models configuration rather than exposing dedicated per-link byte counters, this traffic-skew check is normally done in conjunction with standard interface (IF-MIB) counters.

Configures and monitors IP load-sharing settings on ZyXEL switches, including routing criteria and equal-cost multipath route polling parameters.
