EXECUTIVE SUMMARY

This document serves as the authoritative technical reference for the ZTE ZXR10 Switch Series implementation of Link Aggregation Control Protocol (LACP) Active/Passive mode scripting and hardware-level link aggregation capabilities. Designed for carrier-grade and enterprise network environments, the ZXR10 platform delivers exceptional link reliability, bandwidth optimization, and operational flexibility through its robust LACP implementation. This datasheet provides comprehensive specifications, script configuration guidelines, and hardware architectural insights for network architects, pre-sales engineers, and systems integrators seeking to maximize network resilience and throughput.

HARDWARE ARCHITECTURE & SILICON

The ZXR10 Switch Series leverages a purpose-built, non-blocking switching fabric architecture powered by advanced network processor silicon. The hardware platform integrates high-performance ASICs specifically optimized for link aggregation processing, ensuring line-rate performance across all aggregated member links. The switch architecture supports distributed forwarding engines that maintain per-link state synchronization, enabling seamless LACP negotiation and failover response times below 50 milliseconds. The hardware design incorporates redundant internal data buses and memory subsystems that preserve packet integrity during active/passive mode transitions.

KEY FEATURES & ROUTING LOGIC

- LACP Active/Passive Mode Negotiation: Full support for IEEE 802.3ad/802.1AX standards, enabling dynamic link aggregation formation with proactive (Active) or reactive (Passive) LACPDU transmission.

- Advanced Script-Based Control: Embedded automation framework allowing custom LACP parameter tuning through CLI and Python-based scripting interfaces, including timeout intervals, priority selection, and minimum link thresholds.

- Distributed Link Aggregation Groups (LAGs): Support for up to 128 LAG groups per switch, with up to 16 member ports per group, providing granular aggregation at both access and core layers.

- Hardware-Based Load Balancing: Intelligent distribution of traffic across member links based on Layer 2, Layer 3, and Layer 4 header fields, ensuring uniform utilization and preventing head-of-line blocking.

- Rapid Fault Detection: Proprietary hardware-level link monitoring that triggers automatic link failover within 3-5 milliseconds, independent of software stack delays.

- Resilient Mode Transition: Graceful state handling during Active-to-Passive and Passive-to-Active operational mode changes, ensuring zero packet loss during administrative reconfiguration.
