Depending on whether or not load sharing is implemented, aggregation groups
can be load-sharing or non-load-sharing aggregation groups.
In general, the system only provides limited load-sharing aggregation resources, so
the system needs to reasonably allocate the resources among different
aggregation groups.
The system always allocates hardware aggregation resources to the aggregation
groups with higher priorities. When load-sharing aggregation resources are used
up by existing aggregation groups, newly-created aggregation groups will be
non-load-sharing ones.
The priorities of aggregation groups for allocating load-sharing aggregation
resources are as follows:
