• ZD-S7803M Ethernet Switch Chassis
• Featuring innovative hardware design, the system is powered by a robust control engine, detection engine, and maintenance engine, all independently controlled in a fully distributed manner, ensuring milliseconds-level high reliability.
• Offer comprehensive security protection mechanisms, ensuring network safety across three dimensions: control, management, and forwarding. On the control plane, an integrated protocol message attack identification module prevents attacks such as TCN, ARP protocol messages. OSPF/BGP/IS-IS routing protocols use MD5 verification to prevent network paralysis caused by illegal routing update messages. On the management plane, SNMPv3 network management protocol, SSH V2, user identity authentication based on 802.1x, AAA/Radius, and hierarchical user permission management ensure the security of device management.
• Supports virtualization technology, allowing multiple frame switches to be interconnected, virtualizing them into a single logical frame switch. Users can manage and use these multiple devices as a single unit.
• Supports robust ACL capabilities: Supports standard and extended ACLs; supports VLAN-based ACLs for user-friendly configuration and resource conservation; supports inbound and outbound ACLs to meet strict access control requirements for industries like finance.
• Features a fault-tolerant design with redundant components such as the main control board, power supply, and fans; a passive backplane prevents single points of failure in the chassis; all circuit boards and power modules support hot-swap functionality; the device can operate stably for extended periods in harsh environments, achieving telecommunication-grade reliability of 99.999%.
• Full support for IPv4/IPv6 dual-stack, with various tunneling technologies and IPv4/IPv6 multicast capabilities, providing a comprehensive IPv4/IPv6 solution for users.
• Supports Multi-VRF feature, can be used as an MCE device
Support RRPP ring network technology
