They support link aggregation protocols such as Link Aggregation Control Protocol(LACP) and Static Link Aggregation, which allow multiple physical links to be combined into a single logical connection. This enhances bandwidth, redundancy, and ensures failover capability in. An Aggregation or "Top-of-Rack" switch is designed to connect everything in a rack at high speeds, then have an even bigger pipe out to the rest of the network. The Pro Aggregation does this with it's SFP28 25Gbps ports. By bundling multiple network connections into a single high-bandwidth link, aggregation switches help. For this reason, we've delivered a data center-influenced standalone OLT architecture paired with non-blocking leaf-spine fabric and aggregation switching. A key characteristic of these leaf-spine switching networks is that all leaf switches have full meshed connectivity to the spine switches.
