Intelligent QoS for Multi-Service Optimization
Harnessing cost-cutting IP applications such as VoIP, IPTV and video conferencing in todays modern business environment makes a big difference in market advantages. The Switch 3000 Series provides superior QoS capability to fully utilize the power of applications. Features like multilayer (L2/L3/L4) ACL, 8 priority queues, DSCP and WFQ scheduling algorithm allow you to maximize network bandwidth usage and to provide superior network service quality. With support to MVR and IGMP snooping features, the Switch 3000 Series enables successful IP TV multicasting transmission across multi-VLAN environments. In addition, Fast Leave eradicates streaming quality disturbance when user surf between different channels, while bandwidth control with granularity of 64 kbps brings effortless bandwidth administration to network operators.

Complete Multi-layer Protection
The Switch 3000 Series comes with a 4-layer protection framework against network threats. Multilayer (L2/L3/L4) ACL enables policy-based protection by setting (L2/L3/L4) parameters such as MAC, VLAN, IP Protocol, TCP/UDP, and DSCP. The 4K VLAN range allows maximum administrative freedom on the network. For device access control, MAC freeze and MAC filtering can be configured and the number of MAC addresses on a port can be limited as well. Besides user authentication, IEEE 802.1x provides central network access management and offers further access control on VLAN, bandwidth and traffic priority queues. The intrusion lock feature on the Switch 3000 Series is designed to prevent unauthorized access, and supports to VLAN Stacking can be applied for enterprise-class L2VPN applications. The Switch 3000 Series allows you to implement stricter Layer-1 to Layer-4 security policies.
