Managed L3 Gigabit Switch
- Stato del prodotto (Revision A): Live
The DGS‑3615 Series Managed L3 Gigabit Switches is a new generation of layer 3 networking devices that are designed for building the next‑generation of networking infrastructure. The DGS‑3615 Series provides flexible media interfaces to meet a variety of connection needs required by all of the different media used in network construction. With a full Gigabit interface form factor, scalable high‑density 10 Gigabit Ethernet ports, and 1:1 multilayer switching at full line rates, the DGS‑3615 Series is ideally suitable for the aggregation layer of a large network.
Superior IPv4/IPv6 Multilayer Switching Performance
The DGS-3615 Series Managed L3 Gigabit Switches provides hardware support for IPv4/IPv6 switching at line rates to facilitate the rich tunneling technologies used for communication between IPv6 networks. The DGS-3615 Series can be used in pure IPv4 networks, IPv6 networks, and IPv4/IPv6 dual-stack networks and meets the requirements of current and future networks for a smooth transition from IPv4 to IPv6. The series supports a rich set of IPv4 routing protocols, including static routing protocols, RIP, OSPF, and BGP4, enabling users to select the appropriate protocols needed to build networks for different network environments. The DGS-3615 Series also supports a full suite of IPv6 routing protocols, including static routing protocols, RIPng, OSPFv3, and BGP4+, which are necessary when upgrading an existing network to an IPv6 network or building an IPv6 network.
Virtual Switch Unit (VSU)
Adopting innovative virtualization technology, the DGS-3615 Series utilizes VSU (Virtual Switch Unit) to virtualize up to 8 switches into one logical unit. The DGS-3615 Series VSU technology can also aggregate up to 8 Gigabit Ethernet ports or four 10 Gigabit Ethernet ports as the VSU Link. Managing virtual devices or interfaces is a breeze as the operation management can be unified and simplified through the use of a single IP address, Telnet or CLI session. The VSU technology found in the DGS-3615 Series helps to deliver the highest reliability and availability as there will be zero network interruption when any VSU member leaves or joins into the VSU group. The DGS-3615 Series can implement VSU technology with either Gigabit Ethernet or 10 Gigabit Ethernet ports without limitation on copper or fiber media types.
Flexible and Comprehensive Security Policies
A number of security features are integrated into the DGS-3615 Series to help protect other core devices and networks. Built into the DGS-3615 Series switches is CPU Protection technology which automatically differentiates the traffic of multi-layer protocol IPv4/IPv6 packets destined for the CPU and limits the traffic speed to prevent abnormal packets from attacking the CPU and consuming unnecessary resources. This helps to ensure the stability of CPUs for other core devices and the DGS-3615 Series in the IPv4/IPv6 L3 network and L2 network environments and keeps the network running in an optimal state.
Other security measures include hardware-based IPv6 ACL allows IPv4/IPv6 users to coexist and control the resources access by users. The DGS-3615 Series also implements flexible binding of a port or the system to the IP address and MAC address of a user, strictly limiting user access on a port or in the entire system. There is also support for DHCP snooping, which allows DHCP responses from trusted ports only. By using DHCP listening and by monitoring ARP dynamically and checking the user IP address, the DGS-3615 Series switches discard illegal packets inconsistent with binding entries to effectively prevents ARP and source IP address spoofing.
Superior Multiservice Support Capabilities
The DGS-3615 Series has led the industry in supporting the latest generation international traffic monitoring standard, the IP Flow Information Export (IPFIX). IPFIX technology can take statistics and detect abnormalities of all traffic on the network and export various network traffic analysis reports, including the traffic usage report, history report, interface report, resolvable host addresses, traffic analysis, and variable display. These reports can help an administrator to rapidly analyze problems with the network when abnormalities and provide objective and accurate policy-making references for network capacity planning, network application monitoring, and failure diagnosis to actually implement visibility of network traffic.
The DGS-3615 Series also supports IPv4 and IPv6 multicast functions, including a rich set of multicast protocols such as IGMP Snooping, IGMP, MLD, PIM, PIM for IPv6, and MSDP; all of which provide multicast service support for IPv4 networks, IPv6 networks, and IPv4/IPv6 dual-stack networks. There is also support for Internet Group Management Protocol (IGMP) source port checking and source IP address checking to guard against illegal multicast sources which help improve network security. In addition, the DGS-3615 Series includes layer 3 service features such as Equal-cost Multipath routing (ECMP) and Weighted-cost Multipath routing (WCMP) to meet the communication needs of different link planning.
Rock Solid Reliability
The DGS-3615 Series supports spanning tree protocols (STP) 802.1D, 802.1w, as well as 802.1s to ensure rapid convergence, improve fault tolerance capabilities, ensure stable operation of networks, and provide redundant networking pathways. Virtual Router Redundant Protocol (VRRP) effectively ensure network stability.
Supports Bidirectional Forwarding Detection (BFD) to provide a method for upper-layer protocols such as routing protocols and MPLS to rapidly detect the connectivity of forwarding paths between routing devices, reducing the convergence time of upper-layer protocols greatly in the case of changes in link status.
Advanced QoS Policies
The DGS-3615 Series supports multilayer traffic classification and flow control capabilities such as MAC traffic, IP traffic, and application traffic that implements multiple traffic policies such as refined bandwidth control and forwarding priorities. The DGS-3615 Series switches support the provision of services according to the corresponding QoS level. Layer 2 through 7 traffic classification and perfect Quality of Service (QoS) policies are provided. It also processes different service flows based on different applications to ensure that critical data are transmitted without delay. The QoS guarantee system with DiffServ at its core supports complete QoS policies such as 802.1p, IP ToS, Layer 2 through 7 filter, SP, and WRR.
Ease of Use and Ease of Management
All of the DGS-3615 Series switches allow Telnet access control based on the source IP address to prevent illegal personnel or hackers attacks and strengthen the security of devices. Secure Shell (SSH) and Simple Network Management Protocol v3 (SNMPv3) cryptographic network protocol ensures the security of management information. Other notable features include support for the Network Timing Protocol (NTP) which provides an accurate and consistent timestamp for traffic information analysis and fault diagnosis, support for Syslog to conduct network maintenance and management effectively and port mirroring to help ease the maintenance workload.
