Configuring LAG

Configuration Example

As shown below, hosts and servers are connected to Switch A and Switch B, and heavy

traffic is transmitted between the two switches. To achieve high speed and reliability

of data transmission, users need to improve the bandwidth and redundancy of the link

between the two switches.

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

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.

4) Specify a lower port priority for ports 1/0/9-10 to set them as the backup ports. When

any of ports 1/0/1-8 is down, the backup ports will automatically be enabled to transmit

Demonstrated with T1500G-10PS, the following sections provide configuration procedure

in two ways: using the GUI and using the CLI.
