To prevent the link from the switch to the Wireless LAN Controller (WLC) from becoming overwhelmed as the number of Access Points (APs) and clients increases, **Link Aggregation (LAG)** is often used.
**Functionality of Link Aggregation:**
Link Aggregation combines multiple physical Ethernet links into a single logical link to increase bandwidth and provide redundancy. By aggregating multiple ports between the switch and the WLC, the traffic can be distributed across these links, allowing for higher overall throughput.
This technique functions by using protocols like LACP (Link Aggregation Control Protocol), which helps in the automatic configuration and management of the aggregated links, ensuring load balancing and fault tolerance. As the demand from APs and clients grows, traffic flows over multiple physical connections, effectively managing bandwidth and preventing any single link from becoming a bottleneck. This results in improved performance and reliability of the WLAN infrastructure.
