1x Port Authentication MAC Freeze and Intrusion Lock Back-up Power System Support Multi-layer Aware (L2/L3/L4) ACL for Optimized Traffic Prioritization 8 IEEE 802. 1p Hardware Priority Queues WFQ, WRR and SPQ Queuing Algorithms Versatility for Converged Network Delivery Benefits Empowering Gigabit Converged Networks For mid-sized organizations and enterprise branch offices, the ZyXEL GS-2750 eases converged application deployments and adapts to changing business needs with configuration flexibility, supports to converged network patterns and automation of intelligent network service configurations. In addition, the ZyXEL GS-2750 is optimized for high-density Gigabit Ethernet deployments and includes a diverse range of switches that meet access, aggregation and small network backbone connectivity requirements. Secure Multi-Service Delivery Cooperation of eight priority queues and the WFQ scheduling algorithm secure quality of timesensitive applications, as different services can be assigned to a specific VLAN and configured with different priority for traffic management. The multi-layer ACL provides L2/L3/L4 indicators for conducting policy management on traffic, while IGMP snooping and MVR are supported to optimize IP multicasting applications. Enhanced Multi-layer Security Protection The GS-2750 provides strict security against intruders with mechanisms such as Intrusion Lock, MAC Freeze, Static MAC Forwarding and MAC Filtering for MAC-based protection. The 802. 1Q VLAN isolates traffics into different virtual LANs to protect business-critical information, while Multi-layer ACL provides L2/L3/L4 indicators for security policy management. In terms of access authentication, 802. 1x and TACACS+ are supported for centralized authentication management; 802...
