To achieve high speed and reliability of data transmission, users need to improve the bandwidth and redundancy of the link between the two switches. 3.2.2 Configuration Scheme LAG function can bundle multiple physical ports into one logical interface to increase bandwidth and improve reliability. In this case, we take LACP as an example. As shown below, you can bundle up to eight physical ports into one logical aggregation group to transmit data between the two switches, and respectively connect the ports of the groups. In addition, another two redundant links can be set as the backup. To avoid traffic bottleneck between the servers and Switch B, you also need to configure LAG on them to increase link bandwidth. Here we mainly introduce the LAG configuration between the two switches. Figure 3-1 Network Topology Hosts Gi1/0/1 ... Switch A Gi1/0/10 Gi1/0/1 Gi1/0/10 Switch B Servers The overview of the configuration is as follows: 1) Considering there are multiple devices on each end, configure the load-balancing algorithm as 'SRC MAC+DST MAC'. 2) Specify the system priority for the switches. Here we choose Switch A as the dominate device and specify a higher system priority for it. 3) Add ports 1/0/1-10 to the LAG and set the mode as LACP. User Guide 117
