[. . . ] ■ 16K MAC address table ■ Policy-based QoS optimizes multi-service quality Telco-class Layer 2 Fast Ethernet Switch with Access Control List (ACL) The ZyXEL MES3500-24/MES3500-24F has been specially designed for service providers to deliver profitable Ethernet services. [. . . ] The ZyXEL MES3500-24/MES3500-24F offers a complete set of security features to protect user data while administrating the traffics. 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. MES3500-24 MES3500-24F 24-port FE L2 Switch with Four GbE Combo Ports The MES3500-24/MES3500-24F 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. MES3500-24 MES3500-24F 24-port FE L2 Switch with Four GbE Combo Ports Resilient and redundant design A quick recovery and round-the-clock network is vital for service providers to establish a robust network. The MES3500-24/MES3500-24F 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. Digital Diagnostics Monitoring Interface (DDMI) SFP support The enhanced digital interface allows real-time access to the device operating parameters, and it includes optional digital features such as soft control and monitoring of SFP I/O signals.
