Product Highlights

Cisco Catalyst 2960-Plus switches feature:

• 24 or 48 Fast Ethernet ports

• Small Form-Factor Pluggable (SFP) and 1000BASE-T Gigabit Ethernet uplinks

• IEEE 802.3af-compliant Power over Ethernet (PoE)

• LAN Base or LAN Lite Cisco IOS® Software feature set

• SmartOperations tools that simplify deployment and reduce the cost of network administration

• Cisco EnergyWise technology to manage energy consumed by connected devices

• An enhanced limited lifetime hardware warranty (E-LLW), providing next-business-day replacement

Applications and Benefits

The Cisco Catalyst 2960-Plus Series provides cost-effective, enterprise class Ethernet switching for:

• Branch offices, remote sites, and retail locations

• Conventional desktop workspaces

• Building infrastructure, physical security, and other nontraditional access applications

Benefits of the 2960-Plus include:

• Robust quality of service (QoS) that prioritizes voice and critical business applications

• Flexible security features that can limit access to the network and mitigate threats

• Tools that reduce total cost of ownership through simplified operations and automation

Switch Configurations

Robust Security

The Cisco Catalyst 2960-Plus Series Switches provide a range of security features to limit access to the network and mitigate threats, including:

• Features to control access to the network, including Flexible Authentication, 802.1x Monitor Mode, and RADIUS Change of Authorization

• Threat defense features including Port Security, Dynamic ARP Inspection, and IP Source Guard

• Private VLAN Edge to provide isolation between switch ports

Enterprise-Class Quality of Service

The Cisco 2960-Plus Series Switches offer intelligent traffic management that keeps everything flowing smoothly. Flexible mechanisms for marking, classification, and scheduling deliver superior performance for data, voice, and video traffic, all at wire speed. Primary QoS features include:

• Four egress queues per port and strict priority queuing so that the highest priority packets are serviced ahead of all other traffic

• Shaped Round Robin (SRR) scheduling and Weighted Tail Drop (WTD) congestion avoidance

• Flow-based rate limiting and up to 64 aggregate or individual policers per port

• 802.1p class of service (CoS) and differentiated services code point (DSCP) field classification, with marking and reclassification on a per-packet basis by source and destination IP address, MAC address, or Layer 4 TCP/UDP port number

Cisco Catalyst SmartOperations

Cisco Catalyst SmartOperations is a comprehensive set of capabilities that simplify LAN planning, deployment, monitoring, and troubleshooting. Deploying SmartOperations tools reduces the time and effort required to operate the network and lowers total cost of ownership (TCO).

• Cisco Smart Install enables zero-touch deployment by providing automated Cisco IOS Software image installation and configuration when new switches are connected to the network.

• Cisco Auto Smartports enables automatic configuration of switch ports as devices connect to the switch, with settings optimized for the device type.

• Cisco Smart Troubleshooting is an extensive array of diagnostic commands and system health checks within the switch, including Smart Call Home.

Cisco EnergyWise

Cisco EnergyWise ™ empowers IT teams to measure and manage the power consumed by devices connected to the network, providing measurable energy savings and reduced greenhouse gas emissions. EnergyWise policies can be used to control the power consumed by PoE-powered endpoints, desktop and data-center IT equipment, and a wide range of building infrastructure. EnergyWise technology is included on all Cisco Catalyst 2960-Plus Series Switches.

Power over Ethernet

Cisco Catalyst 2960-Plus switches support IEEE 802.3af Power over Ethernet (PoE) to deliver lower total cost of ownership for deployments that incorporate Cisco IP phones, Cisco Aironet ® wireless access points, or other standards-compliant PoE end devices. PoE removes the need to supply wall power to PoE-enabled devices and eliminates the cost of adding electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments. Table 2 shows the total PoE power available with each 2960-Plus model.

* Intelligent power management allows flexible power allocation across all ports.

Network Management

The Cisco Catalyst 2960-Plus Series Switches offer a superior CLI for detailed configuration and administration. 2960-Plus switches are also supported in the full range of Cisco network management solutions.

Cisco Prime Infrastructure

Cisco Prime ™ network management solutions provide comprehensive network lifecycle management. Cisco Prime Infrastructure provides an extensive library of easy-to-use features to automate the initial and day-to-day management of your Cisco network. Cisco Prime integrates hardware and software platform expertise and operational experience into a powerful set of workflow-driven configuration, monitoring, troubleshooting, reporting, and administrative tools.

Cisco Network Assistant

A PC-based network management application designed for small and medium-sized business (SMB) networks with up to 250 users, Cisco Network Assistant offers centralized network management and configuration capabilities. This application also features an intuitive GUI where users can easily apply common services across Cisco switches, routers, and access points.

Cisco IOS Software

Cisco Catalyst 2960-Plus Series Switches are available with the LAN Base and LAN Lite feature sets. LAN Lite models provide reduced functionality and scalability for small deployments with basic requirements. Note that each switch model is tied to a specific feature level; LAN Lite models cannot be upgraded to the LAN Base feature set.
