Aggregation Group
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
(currently 64 load-sharing aggregation groups can be created at most), 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:
An aggregation group containing special ports (such as 10GE port) which require
■
hardware aggregation resources has higher priority than any aggregation group
containing no special port.
A manual or static aggregation group has higher priority than a dynamic
■
aggregation group (unless the latter contains special ports while the former does
not).
For two aggregation groups of the same kind, 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.
CAUTION: The commands of link aggregation cannot be configured with the
commands of port loopback detection feature at the same time.
You can create a manual aggregation group, or remove an existing manual
aggregation group (after that, all the member ports in the group are removed from
the ports).
You can manually add/remove a port to/from a manual aggregation group, and a port
can only be manually added/removed to/from a manual aggregation group.
