Link Aggregation Configuration; Configuring A Manual Aggregation Group - Huawei Quidway S3100 Series Operation Manual

Operation Manual – Link Aggregation
Quidway S3100 Series Ethernet Switches
The system always allocates hardware aggregation resources to the aggregation
groups with higher priorities. When load-sharing aggregation resources are used up for
existing
non-load-sharing ones.
The priorities of aggregation groups for allocating load-sharing aggregation resources
are as follows:
An aggregation group containing special ports which require hardware
aggregation resources has higher priority than any aggregation group containing
no special port.
For two aggregation groups of the same kind (both contain special ports, or both
contain no special port), the one that might gain higher speed if resources were
allocated to it has higher priority than the other one. If the two groups can gain the
same speed, the one with smaller master port number has higher priority than the
other one.
When an aggregation group of higher priority appears, the aggregation groups of lower
priorities release their hardware resources. For single-port aggregation groups, if they
can transceive packets normally without occupying aggregation resources, they shall
not occupy the hardware aggregation resources.
Caution:
A load-sharing aggregation group contains at least two selected ports, but a
non-load-sharing aggregation group can only have one selected port, while others are
unselected ports.
