Build high-performance data center network
Supports 25G slots to meet the demand for high-density access to 25G servers in high-performance data centers. The 25G slots can support 1G, 10G and 25G module, the 100G slots are backward compatible with 40G modules.
Data center Overlay network
Supports VxLAN. It can meet the requirements of data center Overlay network construction, and solve the problem that the number of VLANS in the traditional data center network is insufficient and the scale is difficult to expand.
Support EVPN* protocol, and the automatic discovery and authentication of VTEPs reduces the flooding of the VxLAN data plane and prevents the dependency of the VxLAN on the multicast of the underlying deployment. This simplifies the VxLAN deployment, improves the construction efficiency of the large layer-2 network, and better meets the deployment requirements of the large Layer-2 network in the data center.
M-LAG architecture
Supports the M-LAG (Multi-chassis Link Aggregation Group) cross-device link aggregation technology. Two physical devices are virtualized into one device at the forwarding layer to achieve cross-device link aggregation. The control layer is independent from each other, which improves board-level reliability to device-level reliability.
Hardware-based traffic visualization
Combined with the hardware capability provided by the chip itself, it can realize the end-to-end traffic visualization in the complex multi-path, multi-node network. Through protocols such as RSPAN and sFlow, the real-time network resource information of the switch can be sent to the operation and maintenance platform of the data center, and the operation and maintenance platform can analyze these real-time data, and realize the functions of network quality backtracking, fault troubleshooting, risk early warning, and architecture optimization.
Carrier-grade reliability protection
Multiple reliability protection at device level and link level. Adopt over current protection, over voltage protection and over heat protection technology. Built-in redundant power modules and fan modules. All power modules and fan modules can be hot-swappable without affecting the normal running of devices. The AC or DC power module can be flexibly configured according to the actual environment requirements.
In addition, the machine supports fault detection and alarm of power supplies and fans. The fan speed can be automatically adjusted according to temperature changes to better adapt to the data center environment and achieve energy saving and emission reduction.
Rich link reliability technologies, such as ERPS fast ring network protection mechanism, MRPP fast link switching mechanism. Supports the BFD fast forwarding detection mechanism. When multiple services and heavy traffic are carried on the network, the convergence time of the network is not affected, ensuring the normal development of services.
IPv4/IPv6 dual stack
The hardware supports IPv4/IPv6 dual-stack multi-layer line-speed switching, differentiates and processes IPv4 and IPv6 packets, and supports multiple Tunnel technologies (such as manual tunnel configuration, automatic tunnel, and ISATAP tunnel). It can provide flexible IPv6 inter-network communication solutions based on IPv6 network requirements and network status.
Rich IPv4 routing protocols, including static routes, RIP, OSPF, IS-IS, and BGP4. A variety of IPv6 routing protocols, including static routes, RIPng, OSPFv3, and BGP4+, can be flexibly selected to build a network whether upgrading an existing network to an IPv6 network or creating an IPv6 network.
Comprehensive security control strategy
Various internal mechanisms can effectively prevent and control virus transmission and hacker attacks, such as preventing DoS attacks and checking the validity of ARP packets on ports.
Multiple hardware ACL policies are secure and reliable. Support inbound and outbound ACLs, and VLAN-based ACLs are delivered. Control illegal users to use the network and ensure legitimate users to use the network properly, such as multi-group binding, port security, time ACL, and bandwidth limiting based on data flow, to meet the requirements of enterprise networks and campus networks to strengthen control over visitors and limit communication between unauthorized users.
Excellent management ability
Supports diversified management interfaces, such as Console port, MGMT port, and USB port, SNMPv1/v2/v3, and universal network management platform. Supports the CLI command line, Web NMS, and TELNET to facilitate device management, and supports encryption modes such as SSH2.0 and SSL to make management more secure. Supports file upload and download management in TFTP mode.
Flexible duct orientation options
In order to better match the air duct design of the data center, the switch provides users with a more flexible air duct scheme. When the front and rear air ducts are implemented, users can also select different fan modules to realize different wind directions (power side air or port side air).
