Features and Benefits

Cisco Catalyst 2960 Series Switches with LAN Base software provide:

●

Exceptional performance: Today’s workers run multiple resource-intensive applications,

placing higher demands on networks than ever before. Within the space of just a few

minutes, for example, a single worker might join an online multimedia conference, send a

10-MB spreadsheet to meeting participants, broadcast a marketing video for the team to

evaluate, and query a sales application for the latest real-time data. The Cisco Catalyst

2960 Series supports speeds of up to 1000 Mbps to the desktop, providing the bandwidth

you need to meet rigorous application demands, alleviate bottlenecks, and boost application

performance--enhancing the productivity of your employees while increasing the return on

your existing infrastructure and application investments.

●

Power over Ethernet: Cisco Catalyst 2960 Series Switches simplify the deployment of

solutions such as wireless LANs, IP telephony systems, and IP video surveillance cameras

by delivering simultaneously full 15.4W for up to 24 ports simultaneously. This capability

eliminates the need for separate power supplies for Ethernet-powered devices, as well as

the costs of running additional cable and circuits. The switches also provide intelligent,

integrated PoE management features that give you greater visibility into and control over

your power usage and streamline interoperability in multivendor networks.

●

Cisco Energywise Technology: Cisco EnergyWise is an innovative architecture

embedded in the Cisco Catalyst 2960 switches that enables the measurement of power

consumption in the network infrastructure and network attached devices. The network

discovers Cisco EnergyWise manageable devices, monitors their power consumption, and

takes action based on business rules to reduce power consumption. Cisco EnergyWise

helps to manage power consumption resulting in company-wide optimized power delivery

and reduced energy costs. Together, Cisco EnergyWise technology and Catalyst switches

help reduce Greenhouse Gas (GhG) emissions, optimize power consupmtion and increase

energy cost savings.

●

Enhanced security: Modern businesses face both more serious security threats and more

demanding regulatory compliance requirements than ever before. The Cisco Catalyst 2960

Series with LAN Base software provides a wide range of security features to protect your

business’ important information, keep unauthorized users off the network, guard privacy,

and protect against network downtime due to security breaches. Key features, including:

◦ An enhanced version of the Cisco Identity-Based Networking Services (IBNS) solution,

which employs the 802.1x standard to provide advanced authentication, access control,

and security policy administration provides users access to designated priviledges

Access control lists (ACLs) to restrict sensitive portions of the network and guard against

network attacks by keep unauthorized users off the network

◦ Port-level security features, to limit access to designated addresses

◦ Dynamic Host Configuration Protocol (DHCP) snooping to identify and block spoofing

from untrusted sources

◦ MAC address notification features to monitor the network and allow administrators to

track where and when users enter the network

Data Sheet

◦ Secure encryption of administrative and network management traffic to protect against

eavesdropping and tampering and comply with regulatory requirements such as the

Payment Card Industry (PCI) standard

●

Improved availability and scalability: The Cisco Catalyst 2960 Series with LAN Base

software provides the redundancy and advanced QoS features you need to help ensure that

your employees stay connected and productive at all times. This intelligence allows your

network to more easily accommodate new technology deployments and continually deliver

optimal performance, even as your business and applications evolve. Important high-

availability and scalability features include:

◦ Spanning Tree Protocol enhancements that support increased redundancy and improved

convergence times in the event of a link outage, as well as efficiently optimizing the extra

capacity inherent in a redundant design

◦ Advanced QoS intelligence to classify and prioritize traffic, reducing network congestion

and bottlenecks

◦ Support for the Cisco Redundant Power System (RPS) 2300 solution to provide

transparent power backup of redundant switches

◦ Voice-aware 802.1x port security, which can block malicious data traffic on a port without

affecting voice traffic

●

Advanced QoS intelligence: The Cisco Catalyst 2960 Series with LAN Base software

supports advanced QoS traffic shaping and policing features that give you optimal flexibility

in classifying and prioritizing the traffic on your network. For example, you can prioritize

traffic from mission-critical applications such as enterprise resource planning (ERP) and

voice systems over less delay-sensitive traffic, reducing network congestion and ensuring

baseline performance for the most essential applications. The switches also support rate-

limiting features that allow you to allocate guaranteed bandwidth to specific applications and

users in increments as small as 1 Mbps. Administrators can easily configure these features

through tools such as automatic QoS (Auto QoS), which detects Cisco IP phones and

automatically configures the switch for the appropriate QoS.

●

Superior manageability: The Cisco Catalyst 2960 Series with LAN Base software provides

several management options. The Express Setup feature and the Cisco Network Assistant

management tool provide intuitive, scalable management features to help you easily deploy

and operate your network.. Express Setup feature allows you to set up the switch with a

web-based brower eliminating need for CLI. Using the Cisco Network Assistant’s PC-based

simple graphical interface, wizards, and Cisco SmartPorts tools, you can quickly configure

all your Cisco switches, routers, and wireless access points in your network. Cisco Network

Assistant includes the Cisco Troubleshooting Advisor, which identifies cabling problems,

common configuration errors, and other potential problems in the network and recommends

corrective action. For more extensive management, the switches also support configuration

and integration with Simple Network Management Protocol (SNMP)-based network

management platforms, such as the CiscoWorks LAN Management Solution (LMS).
