YUNPAN board module compatibility for roofing

 Super Big capacity/ High Density Interfaces

• With distributed modular design, non-blocking switching architecture, brand new big-bandwidth fabric, ZXR10 8900E is an advanced core switch in the industry.

• Each single slot of ZXR10 8900E can provide maximally 48*10GE interfaces or 8*40GE interfaces. In the future 8900E will be able to be smoothly upgraded to provide 100G interfaces.

VSC Construct Solid Cloud Core

• ZXR10 8900E supports Virtual Switch Clustering (VSC), which means the virtualization of multiple physical switches into one logical switch. VSC enhances cluster system capacity and port density, while at the same time simplifies simple topology and eases administration.

• Multiple physical switches can be interconnected through the normal line cards. The 80KM interconnection capability makes it possible to implement remote IDC backup.

• The bandwidth of the VSC interconnection can reach 320Gbps, eliminating any possible bottleneck in the VSC system.

• The forwarding inside VSC system is optimized so that there will be least amount of traffic passing between VSC members.

• Switchover between master and slave in VSC system is really fast and the switchover will not cause any service interruption.

Distributed Module Operating System ROS 5.0

• ZXR10 8900E adopts full-distributed modular design: each function module can be loaded or unloaded independently; each process enjoys its dedicated resources alone; the coordination between processes is efficient and secure.

• Each line card has its own CPU, while the main-control card is equipped with a more powerful CPU. Distributed protocol processing helps promote the overall computing efficiency.

• The expansion of management interfaces is flexible. Currently ZXR10 8900E is compatible with management interfaces XML and Netconf.

Multi-service Bearing Capabilities

• ZXR10 8900E supports rich features, including full L2/L3 features, multicast, MPLS L2/L3 VPN, etc.

• ZXR10 8900E supports complete L2/L3 multicast technologies, including administratively scoped multicast, MVR, IGMP Snooping, Filtering, Proxy, Fast Leave, IGMP,PIM-DM/SM, PIM-SSM, DVMRP and MSDP. All these features help operators deploy multicast applications such as video conferencing and video surveillances.

Comprehensive IPv6 Features

•  ZXR10 8900E supports comprehensive IPv6 features, to facilitate the migration to IPv6 network. For example, ZXR10 8900E supports all basic IPv6 features such as ICMPv6, ND, SNMPv6, RADIUSv6; It also supports IPv6 routing protocols such as OSPFv3, IS-ISv6, BGP4+, PIM-SM for IPv6, MLD snooping; Multiple tunnel technologies are also supported including 6to4 tunnel, ISATAP tunnel, 6vPE, 6PE, etc.

Multi-Dimensional Security & Reliability Mechanism Guarantees Ever-online Services

• Security/Reliability related designs in ZXR10 8900E fall into five categories, which are secure architecture, secure management and control, secure operating system, secure calculation and reliable service.

Environment-friendly Innovations

• ZXR10 8900E supports multiple environmental-friendly innovations, including centralized power management, 5 level intelligent fan speed adjustment. All these environmental friendly designs help cut the power consumption.

• ZXR10 8900E supports dying gasp, in case there is a power failure, 8900E can still send out an alarm to the network OAM center, to inform about the reason of the network break down. In this way, the time to do the trouble-shooting on these kinds of events could be minimized.

       ZXR10 8900E series core switch interface module is the line interface card. The line card types provided include Gigabit Ethernet interface board, 10G Ethernet optical interface board and 40G Ethernet optical interface board. All optical interfaces of line cards in ZXR10 8900E series core switches adopt pluggable optical module, so the same line card can support multiple kinds of transmission media and transmission distances. Some line cards provide different types of ports, reducing the number of line cards that may be needed in many cases, so that the use can get the largest profit with minimal investment. Moreover, all user electrical interfaces in the line cards have cable diagnosis function. They can detect the connection of cables at any time, make diagnosis for short circuit and open circuit of cables and point out the position of the faults with a precision of less than 1m.
