Caution:
z
An FE port and a GE port cannot be put into the same aggregation group.
z
Each FE aggregation group can have up to eight FE ports in selected state, and
each GE aggregation group can have up to two GE ports in selected state.
1.1.2 Manual Aggregation
I. Introduction to manual aggregation
Manual aggregation requires manual configuration of aggregation groups and prohibits
the automatic adding and deleting of member ports by the system. When an
aggregation group contains only one port, you cannot remove the port unless you
remove the whole aggregation group.
II. Port status in manual aggregation group
In a manual aggregation group, the ports may be in selected or unselected state. The
selected ports can transceive user service packets, but the unselected ports cannot.
The selected port with the minimum port number serves as the master port of the group,
and other selected ports serve as member ports of the group.
In a manual aggregation group, the system sets the ports to selected or unselected
state by using these rules:
z
The system sets the port with the highest priority to selected state, and others to
unselected state. The priorities of the ports descend in the following order: full
duplex/high speed, full duplex/low speed, half duplex/high speed, half duplex/low
speed.
z
The system sets the ports unable to aggregate with the master port (due to some
hardware limit, for example, there are already eight FE ports in selected state) to
unselected state.
z
The system sets the ports with port attribute configuration different from that of the
master port to unselected state.
1.1.3 Aggregation Group Categories
In terms of load sharing, link aggregation can be one of the two types: load-sharing
aggregation and non-load-sharing aggregation.
In general, the system only provides limited load-sharing aggregation resources
(currently three load-sharing aggregation groups can be created at most), so the
system needs to reasonably allocate the resources among aggregation groups of
different types.
