MCLAG
Multi-Chassis Link Aggregation Group (MCLAG) is a technology that pairs switches to provide redundancy, load balancing, and high availability by presenting multiple switches as a single logical entity.
MCLAG enables two or more switches to appear as one logical switch to connected devices, ensuring seamless failover and uninterrupted traffic flow in the event of a switch or link failure. Active-active link utilization and loop prevention mechanisms further enhance network efficiency and reliability.
MCLAG is transparent to connected devices, simplifying management and allowing for scalable, resilient network architectures. It is widely used in data center, enterprise, and service provider networks to support mission-critical applications and services.
Best practices include robust configuration, regular failover testing, and monitoring for health and performance. Vendor compatibility should be considered to ensure interoperability in diverse environments.
