Brochure Maximum power availability for a converged voice and data network is attainable when a Cisco Catalyst 3560 Series switch is combined with the Cisco RFS 675 Redundant Power System for transparent protection against internal power supply failures and an uninterruptible power supply (UPS) system to safeguard against power outages. Gigabit Ethernet At speeds of 1000 Mbps, Gigabit Ethernet provides the bandwidth to meet new and evolving network demands, alleviate bottlenecks, and boost performance while increasing the return on existing and new infrastructure investments. Today's workers are placing higher demands on networks, running multiple, concurrent applications. For example, a worker joins a team conference call through an IP videoconference, sends a 10 -MB spreadsheet to meeting participants, broadcasts the latest marketing video for the team to evaluate, and queries the customer relationship management (CRM) database for the latest real -time feedback. Meanwhile, a multiple- gigabyte system backup starts in the background, taking advantage of simple and affordable network attached storage (NAS) to comply with regulatory record keeping requirements such as Sarbanes - Oxley. The Cisco Catalyst 3560 Series can scale the access network to 1 Gbps over existing Category 5 copper cabling and make the most of the desktops and notebooks that are now shipping with Gigabit Ethernet network interface cards (NICs) and higher PC bus speeds for full bandwidth utilization. In addition to being easy to deploy, Gigabit Ethernet networks are simpler to maintain with the new Cisco Time Domain Reflectometry (TDR) that helps verify existing cabling. The Gigabit Ethernet models of the Cisco Catalyst 3560 Series also facilitate high-performance Grid and distributed computing in addition to preparing your network to deploy software applications such as Microsoft Exchange, as well as Microsoft Vista's remote imaging, data synchronization, and computer -to- computer search capabilities. Enhanced Security With the wide range of security features that the Cisco Catalyst 3560 Series offers, businesses can protect important information, keep unauthorized people off the network, guard privacy, and maintain uninterrupted operation. The Cisco Catalyst 3560 Series supports a comprehensive set of security features for connectivity and access control, including network admission control (NAC), ACLs, Dynamic ARP Inspection, IP Source Guard, VPN Routing /Forwarding Lite (VRF Lite), port- level security, and identity -based network services with 802.1x and extensions. These features increase LAN security; protect passwords and configuration information; offer options for network security based on users, ports, or MAC addresses; and help quicken responses to intruder and hacker detection. NAC helps organizations to limit damage from viruses and worms by enforcing security - policy compliance on endpoint devices. Availability and Scalability The Cisco Catalyst 3560 Series is equipped with a robust set of features that allow for network scalability and higher availability through IP routing as well as a complete suite of Spanning Tree Protocol enhancements aimed to maximize availability in a Layer 2 network. Enhancements to the standard Spanning Tree Protocol, such as Per -VLAN Spanning Tree Plus (PVST +), Uplink Fast, and Port Fast, as well as innovations such as Flex Links, maximize network uptime. PVST+ allows for Layer 2 load sharing on redundant links to efficiently use the extra capacity inherent in a redundant design. Uplink Fast, Port Fast, and Backbone Fast all greatly reduce the standard 30- to 60- second Spanning Tree Protocol convergence time. All contents are Copyright ©1992 -2006 Cisco Systems, Inc.
