Intelligent switc hing for the ev olving network: Easing network migration, adaptation, and expansion. Catalyst: An agent that precipitates or accelerates a reaction, development, or c hange.
Q: Wh y start with intelligent switc hing? Q: Wh y c hange an ything? A: Because there really isn ’ t any alternative. Just as living things must adapt to changing conditions in their environments, businesses and other organizations must continually adapt their networks to changing requirements.
Q: What about security? Q: How impor tant is QoS? A: QoS is very impor tant— and becoming more so every day . Advanced QoS prioritizes and directs traffic to minimize congestion and ensure applications are allotted the bandwidth they need.
Q: Wh y mak e the move to Gig abit 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.

The Cisco Catalyst Series switches provide a comprehensive set of management tools to simplify the deployment and management of switches and intelligent network services. The CiscoW orks family of W eb-based management tools enables network administrators to easily and quickly deploy end-to-end network services.
Pr oduct Overview 7 • Cisco Catalyst 3550 Ser ies is a new line of enterprise-class, stackable, multilayer switches. With a range of Fast Ethernet and Gigabit Ethernet configurations, it can serve as both a powerful access layer switch for medium enterprise wiring closets, and as a backbone switch for midsize networks.

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.
A VVID Cisco Architecture for V oice, Video, and Integrated Data. As the industry’ s only enterprise-wide, standards-based network architecture, Cisco A VVID provides the roadmap for combining business and technology strategies into one cohesive model.
Fram e 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.
Lay er 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. Lay er 3 The physical layer in the OSI Model.
