The DGS 3000 series supports surge protection on all Ethernet ports, protecting the switch from power surges due to lightning strikes or faulty electrical cabling.
Quality of service
The DGS 3000 series implements a rich set of multilayer QoS/CoS features to ensure that critical network services such as VoIP, video conferencing, IPTV, and IP surveillance are given high priority. Flexible packet classification can be based on various header fields or user-defined packet content to help administrators prioritize network traffic.
Identity-driven network policies
The DGS 3000 series supports authentication mechanisms for strict access control to network resources. After authentication, individual policies such as VLAN membership, QoS policies, and ACL rules can be assigned to each host.
