This document is the operation manual for Huawei Quidway E series Ethernet switches, including the data forwarding process in switching networks, multicast services, etc.
The manual provides an overview of data forwarding processes in Huawei Quidway E series Ethernet switches, covering simple forwarding, same‑VLAN and different‑VLAN communication, and user Internet access. It also describes how the switches support operable and manageable networks with features such as multicast, NAT, and authentication.
Key sections detail the DHCP address acquisition workflow, ARP resolution, VLAN configuration, multicast routing, and 802.1x authentication with RADIUS integration. The appendix includes a comprehensive list of abbreviations used throughout the document. This manual is written in Chinese.
The client broadcasts a DHCP Discover request, receives an Offer from the server, sends a Request, and finally receives an Ack before using the assigned IP address.
The switch supports 802.1x, forwarding EAPOL frames to a RADIUS server which validates the credentials and returns authentication results.
