is avoided by ensuring that voice traffic is properly classified and prioritized throughout the network. Other applications, such as Web browsing, can

be treated as low priority and handled on a best-effort basis.

The Cisco Catalyst 3560 Series can perform rate limiting through its support of the Cisco Committed Information Rate (CIR) function. Through CIR,

bandwidth can be guaranteed in increments as low as 8 kbps. Bandwidth can be allocated based on several criteria, including MAC source address,

MAC destination address, IP source address, IP destination address, and TCP or UDP port number. Bandwidth allocation is essential when network

environments require service-level agreements or when it is necessary for the network manager to control the bandwidth given to certain users.

MANAGEMENT

The new Cisco Express Setup feature simplifies the initial configuration of a switch. Users now have the option to set up the switch through a Web

browser, eliminating the need for more complex terminal-emulation programs and knowledge of the command-line interface (CLI). Cisco Express

Setup reduces the cost of deployment by helping less-skilled personnel quickly and simply set up switches.

Cisco Network Assistant is a PC-based network-management application optimized for LANs of small and medium-sized businesses with up to

250 users. Cisco Network Assistant offers centralized management of Cisco switches, routers, and WLAN access points. It supports a wide range

of Cisco Catalyst intelligent switches from Cisco Catalyst 2950 through Cisco Catalyst 4506. Through a user-friendly GUI, users can configure and

manage a wide array of switch functions and start the device manager of Cisco routers and Cisco wireless access points. A few mouse clicks enable

the Cisco recommended security, availability, and QoS features without the need to consult a detailed design guide. The Security wizard

automatically restricts unauthorized access to servers with sensitive data. Smartports and wizards save hours of time for network administrators,

eliminate human errors, and help ensure that the configuration of the switch is optimized for these applications. Available at no cost, Cisco Network

Assistant can be downloaded from Cisco.com.

In addition to the Cisco Network Assistant, the Cisco Catalyst 3560 Series switches provide for extensive management using SNMP network-

management platforms such as CiscoWorks for Switched Internetworks. Managed with CiscoWorks, Cisco Catalyst switches can be configured and

managed to deliver end-to-end device, VLAN, traffic, and policy management. Additionally, the CiscoWorks Resource Manager Essentials, a Web-

based management tool, helps enable automated inventory collection, software deployment, easy tracking of network changes, views into device

availability, and quick isolation of error conditions.

CISCO CATALYST 3560 SFP INTERCONNECT CABLE

The Cisco Catalyst 3560 SFP Interconnect Cable (see Figure 2) provides for a low-cost point-to-point Gigabit Ethernet connection between Catalyst

3560 switches. The 50cm cable is an alternative to using SFP transceivers when interconnecting Catalyst 3560 switches through their SFP ports over

a short distance.
