Introduction
The Catalyst 2900 series XL switches are workgroup Ethernet switches that supply
autosensing 10BaseT or 100BaseT connections on all ports. These switches–also referred
to as the Catalyst 2900 series–can be deployed as backbone switches aggregating 100BaseT
traffic from other switches and hubs or in mixed configurations connecting hubs, switches,
servers, and desktops.
This chapter is a functional overview of the Catalyst 2900 series. The following topics
briefly describe the components and features that are shared by all switches in the series:
Summary of key features
Descriptions of the front and rear panels
Software and management options for the switches
Examples of the Catalyst 2900 series in different network topologies
Summary of Key Features
The Catalyst 2900 series XL switches are members of an extended network system of
stackable, modular LAN and WAN products that increase LAN performance, connect
remote offices and users, and provide secure access.
Figure 1-1 shows the ve versions of the Catalyst 2900 series, and Table 1-1 lists their key
features.
Table 1-2 lists the Cisco IOS Release 11.2(8)SA4 software that can run on the current and
legacy Catalyst 2900 series XL switches and modules.
