      COME6865-56YC switch is a high-performance high-density uplink switch with 25Gigabit Downlink 100Gigabit Uplink. The whole switch adopts advanced hardware structure design and pluggable power redundancy design. It can support a maximum of 48 *25Gigabit ports, 8*100G uplink ports, provide full port L2/L3 line speed forwarding capability, and support IPV6.
       It provides rich service features and powerful functions, such as ACL policies, flexible Q-in-Q, and network security protection. At the same time, the product has the highest 10Gigabit port density and the largest switching capacity of the same grade equipment in the industry, and supports full-port line speed forwarding. 
       The elastic stack function virtualizes multiple devices into a logical entity, which can expand port and switching capacity, and manage, upgrade, and maintain multiple devices in a unified manner. To meet the requirements of large data traffic and non-blocking transmission in data centers, the product provides powerful cache capabilities and supports advanced cache scheduling mechanisms to ensure the maximum effective utilization of the device's cache capabilities. It is designed to meet the requirements of high-density and high-bandwidth network applications in next-generation enterprise networks, data centers and metropolitan area networks.

       This device can be applied to the Ethernet aggregation layer or access layer of network operators or campuses, as well as the access layer of data centers and the core layer of small and medium-sized enterprises, and provides rich server access solutions for data centers.
