Configuration Guide
MAC Configuration Guide
MAC (Media Access Control) address, also known as a physical address or hardware address. In the Internet, an IP address cannot specifically identify a user because anyone can change it, whereas the MAC address is written inside network card at the time of manufacture by the manufacturer of the network equipment and can uniquely identify a user.
VLAN Configuration Guide
Ethernet is a data network communication technology based on CSMA/CD (Carrier Sense Multiple Access/Collision Detection) shared communication medium. When the number of hosts is high, it can lead to serious conflicts, broadcast flooding, significant performance degradation and even network unavailability.
LAG Configuration Guide
Link Aggregation increases link bandwidth, enables load sharing of traffic and improves link reliability by aggregating multiple physical links together to form a single logical link. As shown below, Device A and Device B are connected by three physical links, which are bundled into one logical link with a maximum bandwidth equal to the total bandwidth of the three physical links.
ARP/ND Configuration Guide
ARP (Address Resolution Protocol) is a protocol for obtaining MAC addresses based on IP addresses. Main frame sends messages broadcasting an ARP request containing the target IP address to all hosts on the local area network and receives return messages, which determines the physical address of the target; upon receipt of the return packets, the IP address and physical address are stored in the local ARP cache and retained for a certain period of time, and the ARP cache is queried directly on the next request to save resources.
ECMP Configuration Guide
Equal-Cost Multi-Path is an important technology for improving network performance and reliability. Through specific algorithms, network traffic is evenly distributed to multiple links or ports, avoiding congestion on a single link or port due to excessive traffic and fully utilizing network bandwidth resources.
Basic Routing Configuration Guide
Route is the most fundamental element in a data communication network. Routing information is the path information that guides the sending of packets, and the process of routing is the process of packet forwarding.
BGP Configuration Guide
BGP (Border Gateway Protocol) is a distance vector routing protocol that enables route reachability between AS (Autonomous System) and selects the best route. To facilitate the management of the growing network, the network is divided into different autonomous systems.
OSPF Configuration Guide
OSPF (Open Shortest Path First) is an internal gateway protocol based on link state developed by the IETF organization, which is used to announce routing information in a single autonomous system. It has the advantages of fast convergence of routing changes, no routing loops, support for variable-length subnet masks (VLSM), and support for area division, etc.
Policy-Based Routing Configuration Guide
Policy-Based Routing (PBR) is a routing mechanism that forwards packets based on custom-defined policies. When packets are routed, they can be matched based on source IP address, destination IP address, IP protocol, source TCP/UDP port number, and destination TCP/UDP port number.
VRF Configuration Guide
VRF (Virtual Routing Forwarding) is also known as a VPN-instance. VRF is a logical division of physical devices.
IP Multicast Routing Configuration Guide

MC-LAG Configuration Guide
MC-LAG (Multi Chassis Link Aggregation Group) is a mechanism for implementing cross-device link aggregation by aggregating one device with two other devices across the switch, retaining all the benefits of normal link aggregation while providing device-level redundancy. MC-LAG provides a horizontal virtualization technique that virtualizes two physical devices into a single logical device, and this virtualized "single device" is "one-to-one" with its connected uplink or downlink device for link aggregation.
EVPN Multihoming Configuration Guide
EVPN Multihoming is similar to MC-LAG and provides support for master/master redundancy. When the BGP EVPN control plane is used, a Host device is connected to two or more access switches.
VRRP Configuration Guide
VRRP, which stands for Virtual Router Redundancy Protocol, is a protocol that creates a virtual router by grouping multiple devices together. By configuring the IP address of this virtual device as the default gateway, it achieves backup for the default gateway.
