  • Comprehensive QoS features
    Port-based or 802.1p-based prioritization. Layer 3-based (DSCP) prioritization. Port-based ingress and egress rate limiting. Advanced controls for optimized network performance and better delivery of mission-critical traffic such as voice and video.
  • DHCP Snooping
    Ensure IP address allocation integrity by allowing only clients with specific IP/MAC addresses to have access to the network.
  • Dual firmware images and configuration files
    Dual firmware image and dual configuration file for transparent firmware updates/configuration changes with minimum service interruption.
  • Protected ports
    Ensure no exchange of unicast, broadcast, or multicast traffic between the protected ports on the switch, therefore, improve the security of your converged network where your sensitive phone conversation can stay private and your surveillance video clips can be forwarded to their designated storage device without leakage or alteration.
  • Dynamic ARP inspection
    Prevents a class of man-in-the-middle attacks, where an unfriendly station intercepts traffic for other stations by poisoning the ARP caches of its unsuspecting neighbors.
  • Multicast VLAN registration
    Eliminates the replication of the same multicast traffic for every VLAN by sending multicast traffic only on to the dedicated multicast/source VLAN, resulting in more efficient utilization of network bandwidth.
