Fast EtherHub 3500 System User’s Guide

Attaching the Stack to Multiple Segments

This example shows 3 independent Ethernet LANs in a stacked system. Hubs 1 and 2 are attached to segment 1, while hubs 3 and 4 are attached to segment 2, and hubs 5 and 6 are attached to segment 3.

This configuration serves to both balance the network load and improve performance. Using three separate segments provides 300 Mbps of Ethernet bandwidth to the overall stack. Moreover, using a segmented configuration serves to confine the effects of heavy loading or network problems to a single segment.

Figure 3-2 Attaching Hubs in Stack to Three Segments

ΦTraffic in each segment is restricted to that segment and cannot pass to another segment without a device such as a SmartExtender Module or one of Accton’s Fast Ethernet Switches to link them.
