How many aggregation ports does a switch use

Link Aggregation is used to increase the available bandwidth between the firewall and a switch by aggregating up to four interfaces into a single aggregate link, referred to as a Link Aggregation Group (LAG). All ports in an aggregate link must be connected to the same switch. This feature is useful for high end deployments requiring more than 1 Gbps throughput for traffic flowing between two interfaces. This functionality is. An 8-port, Layer 2 switch made for 10G SFP+ connections. The regular Aggregation switch is best used to connect all devices in a rack. There are three single points of failure inherent to a typical port-cable-port connection, in either a computer-to-switch or a switch-to-switch configuration: the cable itself or either of the ports the cable is plugged into can fail.
