These QoS features allow network administrators to prioritize mission-critical and bandwidth-intensive traffic, such as enterprise resource planning
(ERP), voice (IP telephony traffic), and computer-aided design and manufacturing (CAD/CAM), over applications such as FTP or e-mail. For
example, it would be undesirable to have a large file download destined to one port on a switch increase latency in voice traffic destined to another
port on this switch. This condition is avoided by ensuring that voice traffic is properly classified and prioritized throughout the network. Other
applications, such as Web browsing, can be handled on a lower-priority basis.
The Cisco Catalyst 2960 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 small as 1 Mbps. 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 to control the bandwidth given to certain users.
MANAGEMENT
The new Express Setup feature simplifies the initial configuration of a switch. Now you can set up the switch through a Web browser, eliminating the
need for terminal-emulation programs and the command-line interface (CLI). Express Setup reduces the cost of deployment by helping less-skilled
personnel quickly and easily set up switches.
Cisco Network Assistant is a PC-based network-management application optimized for LANs 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 2960 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 time for network administrators, reduce 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 the Cisco Website.
In addition to Cisco Network Assistant, Cisco Catalyst 2960 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.
