Cisco Catalyst 2960-Plus. Switch type: Managed, Switch layer: L2. Basic switching RJ-45 Ethernet ports type: Fast Ethernet (10/100), Console port: RJ-45. Networking standards: IEEE 802.1p, IEEE 802.1x, IEEE 802.3af. Security algorithms: 802.1x RADIUS. Colour of product: Black
The Cisco Catalyst 2960 LAN Lite Switches support security features that can help your business protect important information, keep unauthorized people off the network, guard privacy, and maintain uninterrupted operation. The Cisco Identity-Based Networking Services (IBNS) solution provides authentication, access control, and security policy administration to secure network connectivity and resources. Cisco IBNS in the Cisco Catalyst 2960 LAN Lite series prevents unauthorized access and helps ensure that users get only their designated privileges. With Cisco IBNS you can dynamically administer granular levels of network access. Using the 802.1x standard and the Cisco Secure Access Control Server (ACS), you can assign users a VLAN upon authentication, regardless of where they connect to the network.
- Ease of use: deployment
The Cisco Catalyst 2960 LAN Lite Switches are equipped with features that allow for network scalability and higher availability through multicast filtering as well as a complete suite of spanning tree protocol enhancements for maximizing availability in a layer 2 network. Enhancements to the standard spanning tree protocol help to maximize network uptime. PVST+ allows for layer 2 load sharing on redundant links to efficiently use the extra capacity inherent in a redundant design. UplinkFast, PortFast, and BackboneFast all greatly reduce the standard 30- to 60-second spanning tree protocol convergence time. The loop-guard and bridge-protocol-data-unit (BPDU) guard enhancements provide spanning tree protocol loop avoidance.
- Quality of Service (QoS)
The Cisco Catalyst 2960 LAN Lite Switches offer QoS features to help ensure that network traffic is classified and prioritized and that congestion is avoided in the best possible manner. To implement QoS, the Cisco Catalyst 2960 Series Switches first identify traffic flows or packet groups, and then classify or reclassify these groups using the 802.1p Class of Service (CoS) field. The Cisco Catalyst 2960 LAN Lite Switches support four egress queues per port, giving your network administrators more control in assigning priorities for the various applications on the LAN. At egress, the switches perform congestion control and scheduling, the algorithm or process that determines the order in which queues are processed. The Cisco Catalyst 2960 LAN Lite Switches support Shaped Round Robin (SRR) and Strict Priority Queuing (SPQ). The SRR algorithm helps ensure differential prioritization.
The 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 set up switches quickly and easily. Through a user-friendly GUI, you 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.
The Cisco® Catalyst® 2960-S and 2960 Series Switches are the leading Layer 2 edge switches, providing improved operational excellence, highly secure business operations, improved sustainability, and an enhanced workspace experience. They are fixed-configuration access switches designed for entry-level enterprise, midmarket, and branch office networks. Figure 1 shows the Cisco Catalyst 2960-S Series Switch model and Figure 2 shows the Cisco Catalyst 2960 Series Switch model with LAN Lite software.
The Cisco Catalyst 2960 Series Switches with LAN Lite Software have the following capabilities:
- Fast Ethernet connectivity with Power over Ethernet (PoE) of up to 15.4W per port
- GbE for data connectivity
- Enhanced troubleshooting for problem solving, including link connectivity and cable diagnostics
- Single IP address management for up to 16 switches
- A wide range of software features to provide ease of operation, highly secure business operations, sustainability, and a borderless networking experience
- Limited lifetime hardware warranty
The Cisco Borderless Network Architecture delivers the new workspace experience, connecting anyone, anywhere, using any device, to any resource securely, reliably, and transparently. The Cisco Borderless Networks architecture addresses primary IT and business challenges to help create a truly borderless experience by bringing interactions closer to the employee and customer.
Borderless experience is only possible with intelligent network elements designed and architected to meet the needs of a global workspace. Cisco Network Access is a primary component of this architecture, enabling various borderless network services such as mobility, security, EnergyWise, and ease of operations for increased productivity and operational efficiency.
Cisco Network Access for Borderless solution focuses on the following primary areas:
- Ease of operations
- Borderless security
- Borderless experience
Cisco Catalyst switching solutions enable greener practices through measurable power efficiency, integrated services, and continuous innovations such as Cisco EnergyWise, an enterprisewide solution that monitors and conserves energy with customized policies. Together, Cisco EnergyWise technology and Cisco Catalyst switches reduce greenhouse gas (GhG) emissions and increase energy cost savings and sustainable business behavior. Sustainability features in the Cisco Catalyst 2960-S and 2960 Series Switches include the following features sets:
- Cisco EnergyWise technology
- Efficient switch operation
- Intelligent power management
Cisco EnergyWise Technology
Cisco EnergyWise is an innovative architecture, added to fixed configuration switches, promoting companywide sustainability by reducing energy consumption across an entire corporate infrastructure and affecting more than 50 percent of global greenhouse gas emissions created by worldwide building infrastructure, a much greater effect than the 2 percent generated by the IT industry. Cisco EnergyWise enables companies to measure the power consumption of network infrastructure and network-attached devices and manage power consumption with specific policies, reducing power consumption to realize increased cost savings, potentially affecting any powered device.
EnergyWise encompasses a highly intelligent network-based approach to communicate messages that measure and control energy between network devices and endpoints. The network discovers Cisco EnergyWise-manageable devices, monitors their power consumption, and takes action based on business rules to reduce power consumption. EnergyWise uses a unique domain-naming system to query and summarize information from large sets of devices, making it simpler than traditional network management capabilities. Cisco EnergyWises management interfaces allow facilities and network management applications to communicate with endpoints and each other using the network as a unifying fabric. The management interface uses standard Simple Network Management Protocol (SNMP) or TCP to integrate Cisco and third-party management systems
Efficient Switch Operation
Cisco Catalyst 2960-S and 2960 Series Switches, designed and engineered by Cisco, provide optimum power saving, low power operations for industry best-in-class power management, and power consumption capabilities. The Catalyst 2960-S ports are capable of reduced power modes so that ports not in use can move into a lower power utilization state
