ZyXEL Communications, Inc. 24-port FE L2 Switch ES-3124F

Telco-class Layer 2 Fast Ethernet Switch with Access Control ListMeeting industry standards The Metro Ethernet Forum (MEF) is a global industry alliance comprised of more than 145 active members representing Carrier Ethernet industry groups. The forum develops technical specifications and implementation agreements to promote interoperability and deployment of Carrier Ethernet services worldwide. The ZyXEL ES-3124F 24-port FE L2 Switch is aligned with carrier-class standards for Ethernet Private Line (EPL), Ethernet Virtual Private Line (EVPL) and Ethernet LAN (E-LAN) of Metro Ethernet Forum (MEF), and the Series has been certified as MEF-9 and MEF-14 compliant. Advanced QoS for significant services Consistent service quality and reliable connecting ability in a converged network is the key for service providers to win customers and build loyalty; therefore the ability to control traffic flow and set traffic policy becomes more critical than ever. The ES-3124F offers wire-speed flow control that classifies and prioritizes the incoming packets according to the predefine QoS policies that meet requirements of service providers. In terms of classification, the Differentiated Services Code Point (DSCP) field and the 802.1p Class of Service (CoS) field are identified to assess the priority of incoming packets. Classification and reclassification can be based on criteria as specific as rules based on IP, MAC addresses, VLAN ID or TCP/UDP port number. For bandwidth management, the ES-3124F provides 8 priority queues per port for different types of traffics, allowing service providers to set rule-based rate limitations that take full advantage of constrained network resources and guarantee the best performance. Enhanced security for protection among customers Avoiding subscribers affecting each other on a shared network or shared device is a major concern for service providers. The ES-3124F offers a complete set of security features to protect user data while administrating the traffics. The intrusion lock function detects the “plugged” and “unplugged” status change of Ethernet cables, and the switch would deactivate a specific port automatically if needed, and the 802.1X authentication can secure the network from unauthorized users. Port security provides the ability to deny unauthorized users from accessing the network. Moreover, the 802.1X feature cooperating with RADIUS is useful to prevent unauthorized access based on username and password (or other credentials) and acts as powerful access control for converged networks with mixed wired and wireless access. The ES-3124F provides a multilayer (L2/L3/L4) ACL suite of sophisticated policy-based control mechanisms that enables service providers to deploy easily based on actual network environment needs via a Web GUI or command line interface to prevent abnormal or illegal access. The policies can be defined to deny packets based on source and destination MAC addresses, IP addresses or TCP/UDP ports. Resilient and redundant design A quick recovery and round-the-clock network is vital for service providers to establish a robust network. The ES-3124F provides comprehensive features to make sure network is well operated. The IEEE 802.3ad Link Aggregation feature reduces network downtime by providing redundant paths and bandwidth aggregation to critical connections, while IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) and IEEE 802.1s Multiple Spanning Tree Protocol (MSTP) allow immediate recovery from failed connections by sending packets via the backup link. Furthermore, since the ES-3124F supports backup power system, the power is supplied to the switch in case of an unexpected outage. Intelligent fan control algorithm for power saving Fans play an important role in energy consumption since it’s the key to heat dissipation. The ES-3124F features auto temperature detection and appropriate fan speeds with the Intelligent Fan Control algorithm based on complex mathematics and physics formulas. When the ambient temperature is low, the switch would decrease fan speed to prevent unnecessary power waste from excessive cooling.
