Overview 1-31

Distributed 100BaseT Backbone with Multiple Switches

Figure 1-9 illustrates a network conﬁguration that uses the 100BaseT ports on multiple

Catalyst 1900 switches to interconnect workgroups and network resources. All workgroups

have full access to the network resources (such as a Dynamic Host Conﬁguration Protocol

(DHCP)/Bootstrap Protocol (BOOTP) server or an IPTV multicast server).

You optimize your network performance by placing workstations on the same logical

segment as the servers they access most often. This conﬁguration reduces the amount of

trafﬁc that travels over a network backbone, which is a high-bandwidth (such as Fast

Ethernet) connection between the segments. A backbone is required if numerous users

access the servers.

When the 100BaseT ports are conﬁgured for full-duplex operation, they provide a total of

200 Mbps of bandwidth on each switch port. Switched 10BaseT ports conﬁgured for

full-duplex operation provide 20 Mbps of bandwidth to workstations.

For increased performance to the workstations, replace the hubs shown in Figure 1-9 with

Catalyst 1900 switches. In place of the Catalyst 1900 switches, you can add Catalyst 2900

XL or Catalyst 3500 XL switches and form a switch cluster of Catalyst 1900, Catalyst 2900

XL, and Catalyst 3500 XL switches. A Catalyst 3500 XL switch can be the command

switch, the central point of network management. As your network grows, you can add

more switch clusters.
