Product description

24-Ports of Fast Ethernet Desktop Connectivity
• Dual-purpose uplinks for Gigabit Ethernet uplink flexibility, allowing use of either a copper or fiber uplink; each dual-purpose uplink port has one 10/100/1000 Ethernet port and one SFP-based Gigabit Ethernet port, with one port active at a time. A wide range of software features is present to provide ease of operation, highly secure business operations, sustainability and a borderless networking experience.

Power over Ethernet Plus PoE+
• The Cisco Catalyst 2960 switch provides a lower total cost of ownership for deployments that incorporate Cisco IP phones, Cisco Aironet wireless LAN (WLAN) access points, or any IEEE 802.3af-compliant end device. PoE removes the need for wall power to each PoE-enabled device and eliminates the cost for additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments.

Borderless Networks
• The Cisco Catalyst 2960 consists of borderless networks and a Cisco architecture, that delivers the new workspace experience, connecting anyone, anywhere, using any device, to any resource securely, reliably and transparently. Cisco's borderless network 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, sustainability, EnergyWise and ease of operations for increased productivity and operational efficiency. When network access is intelligent, it knows the identity of the user, as well as where the user is on the network. It knows what is connecting to the network, to automatically provision the network for QoS and delivery. It becomes services-aware to optimize user experience. Only with an intelligent access network can your enterprise go borderless securely and transparently. Your business can save energy and simplify operations with better business efficiency and have an optimized total cost of ownership.

Sustainability
• The Cisco Catalyst switching solution enables greener practices through measurable power efficiency, integrated services and continuous innovations such as Cisco EnergyWise, an enterprise wide solution that monitors and conserves energy with customized policies. Together, Cisco EnergyWise technology and Cisco Catalyst switch reduces greenhouse gas emissions and increases energy cost savings and sustainable business behavior.

Cisco EnergyWise Technology
• Cisco EnergyWise is an innovative architecture added to the Cisco Catalyst 2960 switch that promotes 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, and 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 EnergyWise's 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 SNMP or TCP to integrate Cisco and third-party management systems.

  • Private VLAN edge provides security and isolation between switch ports, which helps ensure that users cannot snoop on other users' traffic.
  • Multidomain authentication allows an IP phone and a PC to authenticate on the same switch port while placing them on appropriate voice and data VLAN.
  • Port-based ACLs for layer 2 interfaces allow security policies to be applied on individual switch ports.
  • Secure shell protocol, Kerberos and Simple Network Management Protocol version 3 provide network security by encrypting administrator traffic during Telnet and SNMP sessions. SSH protocol, Kerberos and the cryptographic version of SNMPv3 require a special cryptographic software image because of U.S. export restrictions.
  • Bidirectional data support on the switched port analyzer port allows Cisco Intrusion Detection System to take action when an intruder is detected.
  • TACACS+ and RADIUS authentication facilitates centralized control of the switch and restricts unauthorized users from altering the configuration.
  • MAC address notification allows administrators to be notified of users added to or removed from the network.
  • Multilevel security on console access prevents unauthorized users from altering the switch configuration.
  • Bridge protocol data unit guard shuts down spanning tree port fast-enabled interfaces when BPDUs are received to avoid accidental topology loops.
  • Spanning Tree Root Guard prevents edge devices not in the network administrator's control from becoming Spanning Tree Protocol root nodes.
  • IGMP filtering provides multicast authentication by filtering out nonsubscribers and limits the number of concurrent multicast streams available per port.
  • Dynamic VLAN assignment is supported through implementation of VLAN membership policy server client capability to provide flexibility in assigning ports to VLANs. Dynamic VLAN facilitates the fast assignment of IP addresses.

Borderless Experience

  • Flexlink provides link redundancy with convergence time less than 100 ms.
  • IEEE 802.1s/w Rapid Spanning Tree Protocol and Multiple Spanning Tree Protocol provide rapid spanning-tree convergence independent of spanning-tree timers and also offer the benefit of Layer 2 load balancing and distributed processing. Stacked units behave as a single spanning-tree node.
  • Per-VLAN Rapid Spanning Tree allows rapid spanning-tree reconvergence on a per-VLAN spanning-tree basis, without requiring the implementation of spanning-tree instances.
  • Switch-port autorecovery (Errdisable) automatically attempts to reactivate a link that is disabled because of a network error.

Enhanced Quality of Service
• The Cisco Catalyst 2960 Switch offers intelligent services that keep everything flowing smoothly. Industry-leading mechanisms for marking, classification and scheduling deliver superior performance for data, voice and video traffic, all at wire speed. Following are some of the QoS features supported in the Cisco 2960 Switch:
  • 802.1p class of service and differentiated services code point field classification are provided, using marking and reclassification on a per-packet basis by source and destination IP address, MAC address, or layer 4 TCP/UDP port number.
  • Cisco control-plane and data-plane QoS ACLs on all ports help ensure proper marking on a per-packet basis.
  • Four egress queues per port help enable differentiated management of different traffic types across the stack.
  • Shaped Round Robin scheduling helps ensure differential prioritization of packet flows by intelligently servicing the ingress queues and egress queues.
  • Weighted Tail Drop provides congestion avoidance at the ingress and egress queues before a disruption occurs.
  • Strict priority queuing helps ensure that the highest-priority packets are serviced ahead of all other traffic.
  • Trusted Boundary provides the ability to trust the QoS priority settings if an IP phone is present and to disable the trust setting if the IP phone is removed, thereby preventing a malicious user.
  • Rate limiting is provided based on source and destination IP address, source and destination MAC address, layer 4 TCP/UDP information, or any combination of these fields, using QoS ACLs (IP ACLs or MAC ACLs), class maps and policy maps.
  • Up to 64 aggregate or individual policers are available per Fast Ethernet or GbE port.

Location Awareness and Mobility
• In order to provide delivery of a best-in-class network experience to end users, it's critical for network access to be location aware. A wide variety of devices can appear on the network, both wired (switches, routers, IP phones, PCs, access points, controllers, video digital media players and so on) and wireless (mobile devices, wireless tags, rogues and so on). In many industries, locating assets is primarily a manual process and is time consuming and error prone. The inability to locate assets in real time and to help ensure their availability when and where they are needed limits reaction time and efficiency. Location services answer business-critical questions about both mobile assets and the users of those assets regardless of whether those assets are connecting using wired or wireless and hence directly improve their organization's profitability. Network location services also improve security and accelerate client troubleshooting by locating an asset, user or device on the network.
  • Network visibility and control provide centralized visibility into wired and wireless devices on the network and their location.
  • Location-assisted client troubleshooting enables tracking of wired or wireless clients for quick problem resolution.
  • Asset tracking and improved security provide centralized inventory of wired and wireless devices and asset management for improved business processes.
  • Location based policy allows greater control and visibility. With EnergyWise, power policies can be set up (to reduce the power or shut down the power from a port) based on the location.
  • Cisco Emergency Responder enhances emergency calling from Cisco Unified CallManager. It helps assure that Cisco Unified CallManager sends emergency calls to the appropriate Public Safety Answering Point for the caller's location.
