2.8 Configuration Examples
This section provides several configuration examples of link aggregation in manual load
balancing mode and in static LACP mode.
2.8.1 Example for Configuring Link Aggregation in Manual Load
Balancing Mode
Networking Requirements
As shown in Figure 2-5, the Switch is connected to the SwitchA through an Eth-Trunk. The
link between the Switch and SwitchA must ensure high reliability, and data traffic needs to be
load balanced among the LPUs of the Switch. To meet this requirement, you need to configure
an inter-board Eth-Trunk on the Switch.
