Link Aggregation Classification

Depending on different aggregation modes, the following three types of link aggregation exist:
Manual aggregation
Static LACP aggregation
Dynamic LACP aggregation

Manual Aggregation Group

Introduction to manual aggregation group
A manual aggregation group is manually created. All its member ports are manually added and can be
manually removed (it inhibits the system from automatically adding/removing ports to/from it). Each
manual aggregation group must contain at least one port. When a manual aggregation group contains
only one port, you cannot remove the port unless you remove the whole aggregation group.
