Catalyst 2960-XR switch models include a field-replaceable modular power supply and can accommodate a second power supply.Cisco Network Access for Borderless solution focuses on the following primary areas: Power resiliency with optional dual field-replaceable power supplies IP Lite Cisco IOS® software with dynamic routing and Layer 3 features   Catalyst 2960-X series Software Features All Catalyst 2960-X Series Switches use a single Universal Cisco IOS Software Image for all SKUs. Depending on the switch model, the Cisco IOS image automatically configures the LAN Lite, LAN Base, or IP Lite feature set. LAN Lite models have reduced functionality and scalability for small deployments with basic requirements. Cisco Catalyst 2960-X Family of Switches are available with the LAN Base and LAN Lite feature sets and Catalyst 2960-XR Family of switches are available IP Lite feature sets. Note that each switch model is tied to a specific feature level; LAN Lite cannot be upgraded to LAN Base and LAN Base cannot be upgraded to IP Lite. Network Security The Cisco Catalyst 2960-X Series Switches provide a range of security features to limit access to the network and mitigate threats, including: MAC-based VLAN assignment enables different users to authenticate on different VLANs. This feature enables each user to have a different data VLAN on the same interface. Cisco TrustSec uses SXP to simplify security and policy enforcement throughout the network. For more information about Cisco TrustSec security solutions Comprehensive 802.1X Features to control access to the network, including Flexible Authentication, 802.1x Monitor Mode, and RADIUS Change of Authorization. IPv6 First-Hop Security enhances Layer-2 and Layer-3 network access from proliferating IPv6 devices especially BYOD devices. It protects against rogue router advertisements, address spoofing, fake DHCP replies and other risks introduced by IPv6 technology. Device Sensor and Device Classifier enable seamless versatile device profiles including BYOD devices. They also enable Cisco Identity Services Engine (ISE) to provision identity based security policies. This feature is available on both the 2960-X and the 2960-XR product families. Cisco Trust Anchor Technology enables easy distribution of a single universal image for all models of Catalyst 2960-X by verifying the authenticity of IOS images. This technology allows the switch to perform IOS integrity checks at boot-up by verifying the signature, verifying the Trusted Asset under Management and authenticating the license. Cisco Threat Defense features including Port Security, Dynamic ARP Inspection, and IP Source Guard. Private VLANs restrict traffic between hosts in a common segment by segregating traffic at Layer 2, turning a broadcast segment into a nonbroadcast multi access like segment. This feature is available in IP-Lite feature set only. Unicast Reverse Path Forwarding (uRPF) feature helps mitigate problems caused by the introduction of malformed or forged (spoofed) IP source address into a network by discarding IP packets that lack a verifiable IP source address. This feature is available in IP-Lite feature set only. 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. Access Control Lists (ACLs) for IPv6 and IPv4 for security and QoS ACEs. Secure Shell (SSH) Protocol, Kerberos, and Simple Network Management Protocol Version 3 (SNMPv3) 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. Switched Port Analyzer (SPAN), with bidirectional data support, allows Cisco Intrusion Detection System (IDS) 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 (BPDU) Guard shuts down Spanning Tree Port Fast-enabled interfaces when BPDUs are received to avoid accidental topology loops. Spanning Tree Root Guard (STRG) 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.   Redundancy and Resiliency Cisco Catalyst 2960-X Series Switches offer a number of redundancy and resiliency features to prevent outages and help ensure that the network remains available: Cross-stack EtherChannel provides the ability to configure Cisco EtherChannel technology across different members of the stack for high resiliency. Flexlink provides link redundancy with convergence time less than 100 milliseconds IEEE 802.1s/w Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP) 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 (PVRST+) allows rapid spanning-tree reconvergence on a per-VLAN spanning-tree basis, without requiring the implementation of spanning-tree instances. Cisco Hot Standby Router Protocol (HSRP) is supported to create redundant, fail safe routing topologies in 2960-XR IP-Lite SKUs. Switch-port auto-recovery (Error Disable) automatically attempts to reactivate a link that is disabled because of a network error. Power redundancy with an optional second power supply on 2960-XR models, or with an external RPS on 2960-X models.   Enhanced Quality of Service The Cisco Catalyst 2960-X Series Switches offers 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: Up to eight 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 256 aggregate or individual policers per port. 802.1p class of service (CoS) and Differentiated Services Code Point (DSCP) 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. Cross-stack QoS to allow QoS to be configured across a stack of 2960-X series switches. The Cisco committed information rate (CIR) function provides bandwidth in increments as low as 8 Kbps. 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.   Cisco Catalyst 2960-X Series Switching Database Manager Switching database manager (SDM) templates for LAN Base and IP Lite licenses allows the administrator to automatically optimize the ternary content-addressable memory (TCAM) allocation to the desired features based on deployment-specific requirements. MAC, routing, security, and QoS scalability numbers depend on the type of template used in the switch. Cisco FlexStack-Plus Cisco FlexStack-Plus provides stacking of up to eight 2960-X switches with the optional FlexStack-Plus module. The FlexStack-Plus module is hot swappable and can be added to any Cisco Catalyst 2960-X or Catalyst 2960-XR with a FlexStack-Plus slot. Switches connected to a stack will automatically upgrade to the stack’s Cisco IOS Software version and transparently join the stack without additional intervention. Cisco FlexStack-Plus and Cisco IOS Software offer true stacking, with all switches in a stack acting as a single switch unit. FlexStack-Plus provides a unified data plane, unified configuration, and single IP address for switch management. The advantages of true stacking include lower total cost of ownership and higher availability through simplified management as well as cross-stack features including EtherChannel, SPAN, and FlexLink. To provide investment protection, FlexStack-Plus is backwards-compatible with FlexStack. Cisco Catalyst 2960-X LAN Base switches equipped with a FlexStack-Plus module can be stacked with Catalyst 2960-S and 2960-SF LAN Base switches equipped with a FlexStack module Power Supply The Catalyst 2960-X switches comes with one fixed power-supply and options for an external redundant power supply source (RPS2300). The Catalyst 2960-XR switches support dual redundant power supplies. The Catalyst 2960-XR ships with one power supply by default. The second power supply can be purchased at the time of ordering the switch or as a spare. These power supplies have in-built fans to provide cooling. Intelligent Power over Ethernet Plus Cisco Catalyst 2960-Xseries switches support both IEEE 802.3af Power over Ethernet (PoE) and IEEE 802.3at PoE+ (up to 30W per port) to deliver lower total cost of ownership for deployments that incorporate Cisco IP phones, Cisco Aironet wireless access points, or other standards-compliant PoE/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. The Catalyst 2960-X series PoE power allocation is dynamic and power mapping scale up to a maximum of 740W PoE+ power. The 2960-XR switch configurations offer the additional benefit of dual redundant power supplies. If both power supplies are used, then the 2960-XR shares the load between the two power supplies for non stop power. Power Management The 2960-X switches offer a range industry leading features for effective energy efficiency and energy management. 2960-X Series are the greenest switches in the industry. Switch Hibernation Mode (SHM) is an industry first and available on all 2960-X series switches. This feature puts the switch in ultra low power mode during periods of non-operation such as nights or weekends. Switch Hibernation Mode on the 2960-X switches can be scheduled using EnergyWise compliant management software. IEEE 802.3az EEE (Energy Efficient Ethernet) enables ports to dynamically sense idle periods between traffic bursts and quickly switch the interfaces into a low power idle mode, reducing power consumption. Cisco 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-X Series Switches. Power Management The Cisco Catalyst 2960-X Series adds a new member to its 2960-X family, the WS-C2960X-24PSQ-L (Cool). This is a 24-port 10M/100M/1000M switch that can power up to 8 ports of PoE (first eight ports only) with ability to deliver a sum total of 110W of PoE power. This switch has four Gigabit Ethernet uplinks: two of them SFP and the other two 10M/100M/1000M copper interfaces enabling choice of fiber or copper connectivity to the aggregation point. Some important 2960-X “cool” switch highlights are: Extends a highly secure, intelligent, managed Cisco Catalyst infrastructure with a single Ethernet cable or fiber from the wiring closet. Support for advanced security and intelligent services, including Netflow-Lite and Switch Hibernation, including voice, video, AP powering, and Cisco Enterprise Network services to remote endpoints Less than 12” depth fit in user work spaces where multiple cable runs could be challenging with very low power consumption and heat dissipation Higher MTBF rates due to no moving mechanical parts, no fans help ensure that 2960X cool switch is convenient to be used for colocated applications Easy to deploy using smart-install, configure with auto-smart-ports and device sensors and manage using Cisco Prime or CNA Cisco Enhanced Limited Lifetime Hardware Warranty Cisco Catalyst 2960-X Series Switches come with an enhanced limited lifetime warranty (E-LLW).
