Virtualization for Demand-based Allocation
The DGS-6650 Chassis Switch supports virtualization technology can virtualize 2 devices into one logical unit, which largely minimizes the number of network nodes and reduce maintenance workload. Superior 50~200ms link failover ensures smooth and uninterrupted transmission of key services. The DGS-6650 Chassis Switch supports cross-device link aggregation for easy double uplink to server/switch, effectively maximizing bandwidth investment return.
Multi-processing Modular Operating System
The DGS-6650 Chassis Switch software platform is designed based on the next generation multi-processing modular operating system to integrate the service features such as loosely coupled firewall, wireless and authentication into a unified cloud network operating system. The DGS-6650 software platform also supports full virtualization and offers rich data center and campus network features. The key availability indicators such as multi-processing modules, process backup and hot patch have reached the industry-leading level.
Flexible and Comprehensive Security Policies
A number of security features are integrated into the DGS-6650 Series to help protect other core devices and networks. Built into the DGS-6650 switches is CPU Protection Policy (CPP) 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-6650 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-6650 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-6650 Series switches discard illegal packets inconsistent with binding entries to effectively prevents ARP and source IP address spoofing.
Superior Multiservice Support Capabilities
The DGS-6650 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-6650 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.
Rock Solid Reliability
The DGS-6650 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) and Rapid Link Detection Protocol (RLDP) effectively ensure network stability. RLDP detects the connectivity of links and whether an optical fiber link is normal from both ends and supports the loop detection function based on the port to prevent network faults caused by loopbacks originating from the connection of devices such as hubs to ports.
The DGS-6650 Series also supports Rapid Ethernet Ring Protection Protocol (RERP), a Layer 2 redundancy protocol designed for the core Ethernet network. When loop blocking and link recovery are performed on a master device, the DGS-6650 Series switches will report its link status to the master device without needing to be processed by other non-master devices. This allows the loop blocking time and link recovery to be shorter compared to when STP is used. When STP is disabled, the Rapid Ethernet Uplink Protection Protocol (REUP) can also provide basic link redundancy through a rapid uplink protection function and help to provide faster subsecond-level fault recovery than STP would be able to.
Redundant design of the DGS-6650 Switch Series key components delivers excellent protection: control engine power and fan modules all support 1+1 redundancy. All redundant components are hot-swappable to maximize reliability and availability. Hot patch technology is also supported to enable online upgrade. Support GR for OSPF/IS-IS/BGP and BFD for VRRP/OSPF/BGP4/ISIS/ISISv6/static routing to enable the fast fault detection mechanism of different protocols. The feature minimizes the fault detection time to less than 50ms.
Excellent Energy Efficiency
The internal system is designed for low voltage power supply with high-efficiency modular power to form a more efficient power supply system. The multi-core CPU supports dynamic power management with all Ethernet copper ports implements the Energy-Efficient Ethernet (EEE) standard to save power under light load.
The smart fan supports speed modulations with precise temperature control, energy saving and noise control. The device can function at high temperature for a long period of time or in harsh environment. The DGS-6650 Switch thereby helps clients to maximize savings on air conditioning.
