Cisco’s Catalyst 2900 Series XL is a full line of 10/100 autosensing Fast Ethernet switches from the leader in networking
that combine outstanding performance, ease-of-use and integrated Cisco IOS software. The Catalyst 2900 Series XL includes
five models with different port densities, configuration options, and pricing to meet a broad range of network design
requirements. Available in Standard and Enterprise Editions, the software embedded in Catalyst 2900 Series XL switches is
upgradable so your investment is protected if your network grows or changes.
The modular 24-port Catalyst 2924M XL switch is an excellent aggregation device, as well as the perfect solution for
providing dedicated 10 or 100 Mbps bandwidth to individual users. The modular 12-port, all fiber Catalyst 2912MF XL
switch is ideal for aggregating small and mid-sized campus networks over 100BaseFX fiber connections. The 12-port
Catalyst 2912 XL, 24-port Catalyst 2924 XL and Catalyst 2924C XL switches are ideal for delivering low-cost, highperformance
10 or 100 Mbps bandwidth to individual users and servers.
Catalyst 2900 XL Standard Edition switches include several exceptional features like EtherChannel (TM), Network Time
Protocol, and Cisco Visual Switch Manager software to increase network performance at very affordable prices. All Standard
Edition switches can be upgraded with the purchase of an optional Enterprise Edition Software Upgrade Kit. Enterprise
Edition software includes all the features of the Standard Edition, and adds enhanced end-to-end VLAN support to your
Catalyst 2900 XL switch. Virtual LAN trunks can be created from any port using either 802.1Q protocols or Cisco’s ISL
Cisco Switch Clustering technology is supported on all Catalyst 2900 XL switches. The Catalyst 2900 XL Command
Software upgrade kit is available as an upgrade, allowing users to create a managed network with a single IP address. A
switch cluster may contain up to 16 Catalyst 3500 XL, 2900 XL, and 1900 switches, regardless of physical location,
connected via standards-based Ethernet, EtherChannel (TM), or Gigastack links. The two-port GigaStack GBIC offers a
range of highly flexible stacking and performance options. Users can build stacks of up to nine Catalyst 2924M XL, 2912MF
XL, and 3500 XL switches with the GigaStack GBICs in Gigabit Ethernet module slot.
Key Features and Benefits
• Cisco’s advanced architecture incorporates a switch fabric of 3.2 Gbps and a forwarding rate of 3.0 million packets per
second to deliver wire-speed performance across all ports.
• The two versatile module slots of the Catalyst 2912MF XL and Catalyst 2924M XL provide expansion capabilities,
higher-speed connectivity, and support for eight different feature modules, allowing users the flexibility to upgrade their
networks and preserve their initial investment.
—The four-port 10BaseT/100BaseTX, two-port 100BaseFX, and four-port 100BaseFX modules for the Catalyst
2912MF XL and Catalyst 2924M XL allow customers to easily increase port density and provide higher-speed uplinks
through bandwidth aggregation.
—Single-port Gigabit Ethernet and Asynchronous Transfer Mode (ATM) interface modules provide higher-speed links.
—Each module provides industry-standard 802.1Q and Inter Switch Link (ISL) VLAN trunking support.
• Catalyst 2900 Series XL switches deliver easy-to-use management and advanced security features.
—A Web-based interface, Cisco Visual Switch Manager, allows users to manage a virtual stack of up to five Catalyst
2900 XL switches from anywhere on the network through a standard browser such as Microsoft Internet Explorer or
—Multilevel security on console access prevents unauthorized users from altering the switch configuration.
—Autoconfiguration eases deployment by automatically configuring multiple switches across a network from a single
• Integrated Cisco IOS software provides superior functionality for end-to-end integration, including bandwidth
aggregation, intraswitch VLAN support, hot swap modules, and networked multimedia support.
—Fast EtherChannel technology offers up to 800 Mbps of bandwidth between Catalyst series switches.2 Cisco Product Catalog, March, 2001
—Support for up to 64 port-based VLANs per Standard Edition switch and Spanning Tree Protocol provides broadcast
control, security; and simplified adds, moves and changes.
—Cisco Group Management Protocol (CGMP) Fast Leave support reduces network traffic by allowing a switch to
selectively and dynamically forward IP multicast traffic to targeted end stations, providing network support for
multimedia and minimizing network traffic.
—Support for up to 64 VLAN trunks using 802.1Q and ISL trunking protocols on Enterprise Edition switches provides
broadcast control, security; and simplified adds, moves and changes.
Cisco 1000BaseT GBIC—Gigabit Interface Converter
The Cisco 1000BaseT Gigabit Interface Converter (GBIC) is an ideal solution for Catalyst 3500 Series XL and Catalyst 2900
Series XL customers, providing full duplex Gigabit Ethernet connectivity to high-end workstations and between wiring
closets over existing copper infrastructures. The GBIC technology leverages the industry’s flexible, standards-based
1000BaseX design allowing for a simple and low-cost migration path to Gigabit Ethernet.
The availability of the new 1000BaseT GBIC increases the deployment and application flexibility of the Catalyst 3500 Series
XL and 2900 Series XL with a range of media transceivers that include multiple stacking options, short-and long-haul fiber,
and copper connectivity (including SX, LX/LH, ZX, TX, and Cisco Gigastack converters).
