Link Aggregation Control Protocol (LACP), the IEEE standard protocol for managing bonds, verifies dual-connectedness. LACP runs on the dual-connected devices and on each of the MLAG peer switches. On a dual-connected device, the only configuration requirement is to create a bond. Arista switches support Multi-Chassis Link Aggregation (MLAG) to logically aggregate ports across two switches. Which means, there will be a fiber link from WS-C2960G-48TC-L to the first core and. Switch-to-Switch Aggregation: This is useful in scenarios where you need to interconnect multiple switches to increase the bandwidth available between them and ensure network redundancy. This article explains how MLAG works, its architecture, and how it enhances network resilience.
