Its design is based on the experience learned from today's most widely deployed access switches, the Cisco Catalyst® 2950 Series.<br><br><b>The Cisco ME 2400 Series offers service provider-friendly hardware and mission-specific software,</b><br>including a complete security solution for Metro Ethernet access. This cost-effective solution is optimized for the Ethernet-to-the-home (ETTH) triple-play services.<br><br><b>The SFP-based Gigabit Ethernet ports accommodate a wide range of 100BASE and 1000BASE SFP</b><br>transceivers. The options include Cisco 100BASE-LX, 100BASE-FX, 100BASE-BX, 1000BASE-T, 1000BASE-SX, 1000BASE-LX, 1000BASE-ZX, and coarse wavelength-division multiplexing (CWDM) SFP transceivers. These ports also support the Cisco Catalyst 3560 SFP Interconnect Cable for establishing a low-cost Gigabit Ethernet point-to-point connection.<br><br><b>Service Provider-Friendly Hardware</b><br>Metro Ethernet access switches are typically deployed in the basements of office buildings or in apartments. Service providers are always challenged to find enough space to deploy equipment. To ease this obstacle, the purpose-built Cisco ME 2400 Series is designed with a compact form factor (1RU x 9.52 in.) and flexible mounting options. In addition, the Cisco ME 2400 Series is built with all front-accessed connectors to simplify field installation and troubleshooting.<br><br><b>Metro-Specific Software</b><br>The Cisco ME 2400 Series switches run software specifically designed for the Metro Ethernet market. Many new features are added to make the Cisco ME 2400 Series the optimal access switch for service providers. Many default behaviors of the Cisco ME 2400 Series are different from those of traditional Ethernet switches; these differences make the Cisco ME 2400 Series easier to configure, manage, secure, and troubleshoot.<br><br><b>UNI/NNI</b><br>The Cisco ME 2400 Series software introduces the concept of User-Network Interface/Network-Node Interface (UNI/NNI) for Ethernet access switches. Because the software can identify the application of each port, it can provide many powerful default behaviors.<br><br><b>Comprehensive Security Solution</b><br>As Metro Ethernet networks continue to expand, one of the challenges that service providers face is to provide the same level of security as other access technologies. To meet this challenge, the Cisco ME 2400 Series switches provide the most comprehensive security solution for Ethernet access products. By dividing security into three portions and designing features for each, the Cisco ME 2400 can provide complete solution at the access layer. The three different areas of security the switch addresses are subscriber security, switch security, and network security.<br>The subscriber security helps create protection among customers. One of the biggest concerns about using a shared device for multiple customers is how to prevent customers from affecting each other. The Cisco ME 2400 Series addresses this concern by providing features such as UNI/NNI, DHCP Snooping, and Private VLAN. The UNI/NNI feature creates a circuit-like behavior to separate customers' traffic from each other. DHCP Snooping helps service providers identify each user's MAC address, IP address, and port information and prevents users from attempting DHCP based attacks.<br>The switch security is about protecting the switch itself from attacks. The Cisco ME 2400 Series offers features to protect CPU and configuration files from attacks. CPU is a critical component of an Ethernet switch; it is responsible for process-control protocols such as Spanning Tree Protocol and routing updates; if CPU is under DoS attack, those control packets could be dropped, resulting in network outage. Features such as Control Plane Security and Storm Control protect the CPU against malicious attacks. Port Security is another important security feature; it allows service providers to control the number of MAC addresses each subscriber is allowed - thereby protecting against overwhelming the switch memory.<br>The final area of security is network security. The features designed for this area filter all incoming traffic to help ensure that only valid traffic is allowed through the switch. The Cisco ME 2400 Series switches have features such as access control lists (ACLs) and 802.1x to identify the users and packets that are allowed to transmit traffic through the switch.<br><br><b>Service Management Options</b><br>The Cisco ME 2400 Series offers a superior command-line interface (CLI) for detailed configuration. In addition, the switches support CiscoWorks, the Cisco CNS 2100 Series Intelligence Engine, and the Simple Network Management Protocol (SNMP) for networkwide management. Service providers can integrate the Cisco ME 2400 Series transparently into their operations support systems (OSSs) and enable improved flow-through provisioning.<br>The Cisco CNS 2100 Series network device allows service providers to effectively manage a network of Cisco IOS® Software devices, including the Cisco ME 2400 Series. It is a completely self-contained unit that includes a task-oriented Web GUI, a programmable Extensible Markup Language (XML) interface, configuration template management, and an embedded repository. Network operators can use the Web GUI to quickly turn existing Cisco IOS CLI configuration files into reusable templates. The Cisco CNS 2100 Series integrates easily into existing customer OSSs or business support systems (BSSs) and provisioning systems with its external repository support and the event-based Cisco IOS Software XML interface that effectively "workflow-enables" Cisco device deployment. Service providers also can manage the Cisco ME 2400 Series using SNMP versions 2 and 3. A comprehensive set of MIBs is provided for service providers to collect traffic information on the Cisco ME 2400 Series.<br><br><b>The purpose-built Cisco ME 2400 Series switches help service providers offer a portfolio of</b><br>profitable, differentiated services such as triple-play services for the ETTH market.<br><br><b>Triple-Play Service</b><br>Triple-play service is a popular choice for service providers. By combining Internet access, voice, and video services, service providers can generate higher average revenue per unit (ARPU). Triple-play service provides additional value by increasing customer retention. The Cisco ME 2400 Series switches are optimized for triple-play service. By delivering the primary features in the areas of quality of service (QoS), multicast, and security, the Cisco ME 2400 Series helps service providers deploy successful triple-play service.<br><br>
