Cisco Catalyst 2900 XL Series

Modular Fast Ethernet Switches

The Cisco Catalyst 2900 Series XL switches are standalone, 10/100 auto-sensing Fast Ethernet Switches that combine outstanding performance with ease-of-use and integrated Cisco IOS software. Some features of this line include:

• switch fabric of 3.2 Gbps, a forwarding rate of more than 3 million packets-per-second, and a maximum forwarding bandwidth of 1.6 Gbps, delivering wire-speed performance across all 10/100 ports
• support for IEEE 802.1p protocol for prioritization of mission-critical and time-sensitive applications such as voice and telephony traffic
• Cisco’s switch clustering technology enables up to 16 interconnected Catalyst 1900, 2900XL, and 3500 XL switches, regardless of geographical location, to form a single, flexible IP managed network
• up to 250 port-based VLANs or ISL/802.1Q trunks
• network port allows operation in networks with unlimited MAC addresses
• auto configuration of multiple switches on a network from one boot server
• up to 4 Gbps bandwidth between router, switches, and servers with Fast EtherChannel and Gigabit EtherChannel

The Cisco Catalyst 2950SX-24, 2950-24, and 2950-12, members of the Cisco Catalyst 2950 Series Switches, are standalone, fixed-configuration, managed 10/100 switches providing basic workgroup connectivity for small to midsized networks. These wire-speed desktop switches come with Standard Image (SI) Software features and offer Cisco IOS® functionality for basic data, video and voice services at the edge of the network. Embedded in all Catalyst 2950 Series is the Cisco Cluster Management Suite (CMS) Software, which allows users to simultaneously configure and troubleshoot multiple Catalyst desktop switches using a standard Web browser.

This product line offers two distinct sets of software features and a range of configurations to allow small, midsized, and enterprise branch offices to select the right combination for the network edge. The SI software offers Cisco IOS functionality for basic data, video, and voice services. For networks with requirements for additional security, advanced quality of service (QoS), and high availability, the Enhanced Image (EI) software delivers intelligent services such as rate limiting and security filtering for deployment at the network edge.

The Catalyst 2950SX-24, 2950-12, and 2950-24 switches are only available with the SI software for the Catalyst 2950 Series.

• Catalyst 2950SX-24 Switch—24 10/100 ports with 2 fixed 1000BASE-SX uplinks
• Catalyst 2950-24 Switch—24 10/100 ports
• Catalyst 2950-12 Switch—12 10/100 ports

These switches provide customers with a choice of connectivity options. While the Catalyst 2950-12 and 2950-24 provide 12 and 24 10/100 ports for edge connectivity respectively, the Catalyst 2950SX-24 provides 24 10/100 ports and 2 integrated 1000BASE-SX ports for gigabit uplink connectivity over fiber. With these integrated ports, customers get an extremely cost-effective solution for delivering gigabit speeds using fiber. Dual ports also provide redundancy and increased availability, as well as provide a cost-effective means for cascading switches and managing them as a cluster. This switch is ideal for education and government segments, where fiber uplinks are a requirement.

The Catalyst 2950 Series Intelligent Ethernet Switches with EI Software are also part of the Catalyst 2590 Series switches. These fixed-configuration, stackable models bring intelligent services, such as advanced QoS, enhanced security, and high availability to the network edge—while maintaining the simplicity of traditional LAN switching. When a Catalyst 2950 Intelligent Ethernet Switch is combined with a Catalyst 3550 Series Switch, the solution enables IP routing from the edge to the core of the network.

Cisco Catalyst switches features a comprehensive range of products of increasing functionality, for Ethernet-based platforms. These switches provide diverse interfaces, high port densities, and extensible functionality suitable for converged network access or backbone applications. Catalyst switches provide the scalable network infrastructure with intelligent services that enables organizations to deploy converged internet business solutions to maximize their productivity and competitive advantage.
