Aggregation/ Trunk Configuration
To set up the Port trunk groups, put the ports number into the same
Aggregation group. There are eight groups to choose. Don’t forget to click
the “Apply” to save the setting.
There are three aggregation modes for you to setup, SMAC, DMAC, and XOR.
SMAC mode selects the path of packets according to source MAC while
DMAC mode selects path according to destination MAC. XOR mode
calculates the result of DMAC and SMAC mode to decide the path of packets.
