Run the display eth-trunk command to check the load balancing mode of the Eth-Trunk. By
default, the load balancing mode of the Layer 2 Eth-Trunk is displayed as "SA-XOR-DA" in the
output information.

1.4 Configuring Link Aggregation in Static LACP Mode
This section describes how to configure link aggregation in static LACP mode.
1.4.1 Establishing the Configuration Task
Applicable Environment
To increase the bandwidth and improve the connection reliability, you can configure a link
aggregation group on two directly connected routers. The requirements are as follows:
l The links between two devices can implement redundancy backup. When a fault occurs on
one or more links, the backup links replace the faulty ones to help ensure uninterrupted
data transmission.
l The active links have the load balancing capability.
