determined by the port priority of the system. You can decide whether the port is
selected or standby by setting system priority and port priority.
2.1.4 Load Sharing
In terms of load balancing, link aggregation may be load balancing aggregation and
non-load balancing aggregation. In general, the system only provides limited load
balancing aggregation resources, so the system need to rationally allocate these
resources among manual aggregation groups, static LACP aggregation groups,
dynamic LACP aggregation groups and the aggregation groups including special ports
which require hardware aggregation resources. The system will always allocate
hardware aggregation resources to the aggregation groups with higher priority levels.
When the load sharing aggregation resources are used up for existing aggregation
groups, newly-created aggregation groups will be non-load sharing ones. The priority
levels (in descending order) for allocating load sharing aggregation resources are as
follows:
Aggregation groups including special ports which require hardware aggregation
resources
Manual and static LACP aggregation groups
Aggregation groups that probably reach the maximum rate after the resources are
allocated to them
Aggregation groups with the minimum master port numbers jf they reach the equal
rate with other groups after the resources are allocated to them
When aggregation groups of higher priority levels appear, the aggregation groups of
lower priority levels release their hardware resources. For single-port aggregation
groups, if they can transceive packets normally without occupying hardware resources,
they shall not occupy the resources.
A load sharing aggregation group may contain several selected ports, but a non-load
sharing aggregation group can only have one selected port, while others as standby
ports. Selection criteria of selected ports vary for different types of aggregation groups.
2.2 Link Aggregation Configuration
Link aggregation configuration includes:
Enable/disable LACP at port
Create/delete aggregation group
Add/delete Ethernet port into/from aggregation group
Set/delete aggregation group descriptor
