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 time-

sensitive 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; 802.1x can even

further facilitate the assignment of VLAN and bandwidth.
