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 intelligent access network, your enterprise can go borderless securely and transparently. Your business can save energy, simplify operations with better business efficiency, and have an optimized total cost of ownership.Cisco Network Access for Borderless solution focuses on the following primary areas: Sustainability EnergyWise Ease of operations Borderless security Borderless experience   Sustainability Cisco Catalyst switching solutions enable 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 switches reduce greenhouse gas (GhG) emissions and increase energy cost savings and sustainable business behavior. Sustainability features in the Cisco Catalyst 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 company wide sustainability by reducing energy consumption across an entire corporate infrastructure and affecting more than 50percent 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.   Efficient Switch Operation Cisco Catalyst 2960 Series Switches, designed and engineered by Cisco, provide optimum power savings, 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.   Intelligent Power over Ethernet Management The Cisco Catalyst 2960-S PoE models support the latest PoE+ devices including Cisco IP phones and Cisco Aironet WLAN access points providing up to 30W of power per port, as well as any IEEE 802.3af-compliant end device. Per port power consumption command allows customers to specify maximum power setting on an individual port Per port PoE power sensing measures actual power being drawn, enabling more intelligent control of powered devices Cisco Discovery Protocol Version 2 allows switches to negotiate a more granular power setting when connecting to a Cisco powered device such as IP phones or access points than what is provided by IEEE classification The PoE MIB provides proactive visibility into power usage and allows customers to set different power-level thresholds   Ease of Operations The Cisco Catalyst 2960 Series Switches help reduce the operating costs through: Cisco Catalyst Smart Operations Easy to use deployment and control features Advanced, intelligent network management tools   Cisco Catalyst Smart Operations Cisco Catalyst Smart Operations is a comprehensive set of capabilities that simplify LAN deployment, configuration, and troubleshooting. Cisco Catalyst Smart Operations enable zero touch installation and replacement of switches, fast upgrade, as well as ease of troubleshooting with reduced operational cost. Cisco Catalyst Smart Operations is a set of features that includes Smart Install, Auto Smartports, Smart Configuration, and Smart Troubleshooting to enhance operational excellence: Cisco Smart Install is a transparent plug-and-play technology to configure the Cisco IOS Software image and switch configuration without user intervention. Smart Install utilizes dynamic IP address allocation and the assistance of other switches to facilitate installation providing transparent network plug and play. Cisco Auto Smartports provide automatic configuration as devices connect to the switch port, allowing auto detection and plug and play of the device onto the network. Cisco Smart Configuration provides a single point of management for a group of switches and in addition adds the ability archive and backup configuration files to a file server or switch allowing seamless zero touch switch replacement. Cisco Smart Troubleshooting is an extensive array of debug diagnostic commands and system health checks within the switch, including Generic Online Diagnostics (GOLD) and on board Failure Logging (OBFL). Easy to Use Deployment and Control Features Automatic QoS (AutoQoS) simplifies QoS configuration in voice over IP (VoIP) networks by issuing interface and global switch commands to detect Cisco IP phones, classify traffic, and help enable egress queue configuration. Stacking Master configuration management and Cisco FlexStack stacking helps ensure that all switches are automatically upgraded when the master switch receives a new software version. Automatic software version checking and updating help ensure that all stack members have the same software version. Dynamic Host Configuration Protocol (DHCP) auto configuration of multiple switches through a boot server eases switch deployment. Auto-negotiation on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth. Dynamic Trunking Protocol (DTP) facilitates dynamic trunk configuration across all switch ports. Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel® groups or Gigabit EtherChannel groups to link to another switch, router, or server. Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that conform to IEEE 802.3ad. This feature is similar to Cisco EtherChannel technology and PAgP. Automatic media-dependent interface crossover (MDIX) automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight-through) is installed. Unidirectional Link Detection Protocol (UDLD) and Aggressive UDLD allow unidirectional links caused by incorrect fiber-optic wiring or port faults to be detected and disabled on fiber-optic interfaces. Switching Database Manager (SDM) templates for access, routing, and VLAN deployment allow the administrator to easily maximize memory allocation to the desired features based on deployment-specific requirements. Local Proxy Address Resolution Protocol (ARP) works in conjunction with Private VLAN Edge to minimize broadcasts and maximize available bandwidth. Internet Group Management Protocol (IGMP) Snooping for IPv4 and IPv6 MLD v1 and v2 Snooping provide fast client joins and leaves of multicast streams and limit bandwidth-intensive video traffic to only the requestors. Multicast VLAN Registration (MVR) continuously sends multicast streams in a multicast VLAN while isolating the streams from subscriber VLANs for bandwidth and security reasons. Per-port broadcast, multicast, and unicast storm control prevents faulty end stations from degrading overall systems performance. Voice VLAN simplifies telephony installations by keeping voice traffic on a separate VLAN for easier administration and troubleshooting. Cisco VLAN Trunking Protocol (VTP) supports dynamic VLANs and dynamic trunk configuration across all switch. Remote Switch Port Analyzer (RSPAN) allows administrators to remotely monitor ports in a Layer 2 switch network from any other switch in the same network. For enhanced traffic management, monitoring, and analysis, the Embedded Remote Monitoring (RMON) software agent supports four RMON groups (history, statistics, alarms, and events). Layer 2 traceroute eases troubleshooting by identifying the physical path that a packet takes from source to destination. Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by downloading from a centralized location. Network Timing Protocol (NTP) provides an accurate and consistent timestamp to all intranet switches. Advanced, Intelligent Network Management Tools The Cisco Catalyst 2960 Series Switches offer both a superior CLI for detailed configuration and Cisco Network Assistant software, a PC-based tool for quick configuration based on preset templates. In addition, CiscoWorks LAN Management Solution (LMS) supports the Cisco Catalyst 2960 Series Switches for networkwide management. 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. Cisco Network Assistant uses Cisco Smartports technology to simplify both initial deployment and ongoing maintenance. This application also features an intuitive GUI where users can easily apply common services across Cisco switches, routers, and access points, such as: Configuration management Troubleshooting advice Inventory reports Event notification Network security settings Password synchronization Drag-and-drop Cisco IOS Software upgrades Secure wireless Enhanced Quality of Service The Cisco 2960 Series Switches 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 Series Switches: Cross-stack QoS allows QoS to be configured across the entire Cisco 2960-S Flexstack. 802.1p class of service (CoS) and differentiated services code point (DSCP) 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 (SRR) scheduling helps ensure differential prioritization of packet flows by intelligently servicing the ingress queues and egress queues. Weighted Tail Drop (WTD) 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 (CER) enhances emergency calling from Cisco Unified CallManager. It helps assure that Cisco Unified CallManager sends emergency calls to the appropriate Public Safety Answering Point (PSAP) for the caller’s location.
