If switches use link aggregation, when traffic is aggregated, ensure that PPPoE packets are load balanced. In such scenarios, the S5700EI, S5710EI, S5720EI, S5700HI, S5710HI, S5720HI, S5730SI, S5730S-EI, S6700EI, S6720EI, S6720S-EI, S6720SI, S6720S-SI, S6720LI . An aggregation switch is a network device that consolidates traffic from multiple access switches, wireless access points, or other edge devices and forwards it to core switches or routers. By bundling multiple network connections into a single high-bandwidth link, aggregation switches help. 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. The regular Aggregation switch is best used to connect all devices in a rack. This chapter covers the design recommendations for a data center design deployment consisting of a Cisco Nexus® 7000 Series Switch at the aggregation layer and a Cisco Nexus 5000 Series Switch at the access layer. For this reason, we've delivered a data center-influenced standalone OLT architecture paired with non-blocking leaf-spine fabric and aggregation switching.
