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 RPS 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.
