Wiring Closet Aggregator
Figure 1-17 shows a Catalyst 3508G XL aggregating traffic from two 2900 XL or 3500 XL
switches to an enterprise switch (such as a Catalyst 8500). In this deployment, the
full-duplex connection is either a GigaStack GBIC or a 1000BaseX connection, and the
uplink is either a 1000BaseX or a Gigabit EtherChannel connection.
