  • Page 4 The Evolving Network Q: How important A: QoS is very important— is QoS? and becoming more so every day. Advanced QoS prioritizes and directs traffic to minimize congestion and ensure applications are allotted the bandwidth they need. Without those features, the performance advantages of Gigabit Ethernet (or Fast Ethernet, for that matter) cannot be fully realized.
  • Page 5 Q: Why make the move to Gigabit Ethernet? The primary security features and applications supported by these switches include access control lists (ACLs), filtering, port security, IEEE 802.1x, multilevel console security, and Secure Shell (SSH) Protocol. This unique combination provides the enhanced security needed to support new and expanding network services, addressing three distinct areas of concern in the network: •...
  • Page 6 Network Intelligence—from the Core to the Edge Whatever the size of the network, intelligent services can ease the strain of migration and expansion. By delivering Layer 2– 4 services across the entire network, from the core to the edge, Cisco Catalyst switches provide the advanced quality of service, enhanced security, and high availability evolving networks require.
  • Page 7 A: Lots of reasons—as lots of people can attest. Cisco Systems’ achievements and contributions have made it one of the world’s most admired companies. Service providers, PTTs, governments, academic institu- tions, Fortune 500 companies, and small-to-medium businesses around the world look to Cisco to enable and support their diverse networking requirements.
  • Page 8 Product Overview Cisco CMS Software enables network managers to manage the entire LAN through a single Web interface. Q: What are the differences between the various Cisco Catalyst Series switches? The Cisco Catalyst Series switches provide a comprehensive set of management tools to simplify the deployment and management of switches and intelligent network services.

  • Page 10 Catalyst Wiring Closet Deployment Scenarios Every network is unique, just like the organizations they serve. These diagrams illustrate four common deployments in wiring closets, utilizing Cisco Catalyst 2950, 3550, 4500, and 6500 switches. Depending on the size of the business, these could be linked into the core network layer.
  • Page 11 A network is, and probably always will be, a work in progress. Companies grow, requirements change, and new applications emerge, presenting opportunities for even greater efficiency and productivity. Cisco Catalyst switches are designed to make those transitions almost effortless. They provide stability in an ever-changing landscape, delivering the performance and intelligent services needed to ensure networks evolve efficiently, reliably, and securely.
  • Page 12 Glossary AVVID Cisco Architecture for Voice, Video, and Integrated Data. As the industry’s only enterprise-wide, standards-based network architecture, Cisco AVVID provides the roadmap for combining business and technology strategies into one cohesive model. Availability The amount of time that a network or device is operational —in other words, the likelihood that it will be available for use when needed.
  • Page 13 Glossary Frame The basic unit of Ethernet data traffic. An Ethernet frame can vary in size from a minimum length of 64 bytes to a maximum length of 1522 bytes. An Ethernet frame contains the Ethernet destination address, Ethernet source address, 802.1Q/1p fields, and TCP/IP packet.
  • Page 14 Glossary Layer 2 The data link layer in the OSI Model. For Ethernet, this applies to the Ethernet frame that contains the Ethernet destination address, Ethernet source address and 802.1Q/1p fields. See also Layer 3. Layer 3 The physical layer in the OSI Model. For TCP/IP, this applies to the IP packet that contains the IP destination address, IP source address and ToS byte.
