" Note: Using Auto Uplink to create multiple active paths between any two network devices can cause undesirable loops in the network, resulting in an endless broadcast traffic that disables your network. Loops occur when there are alternate routes between two network devices. In Figure 2-3, for example, a loop is created by connecting two RJ-45 ports on a GS516T Switch to a router containing a 4-port switch. Figure 2-4 shows another scenario where a router with a 4-port switch connects to a hub and to a GS516T Switch; the hub and switch, in turn, connect back to the same router, creating multiple active paths between all three devices.
