Link Aggregation by LAG function.
The Link Aggregation Group (LAG) function allows grouping several links into a single
aggregated link identifier. FIGURE 3 illustrates an example of link aggregation. From
the point of view of the STP/RSTP protocol, the connection entity is the LAG group
identifier. In this way, the different links that are part of the LAG are not handled
individually and are not considered a loop, and thus it provides the aggregated
bandwidth.
Link aggregation can be created for any of the planned interface functions: user (edge,
untag), inter-switch link (trunk or native) and those associated to the Q-in-Q
functionality (access and core). Once the LAG is selected, the set of parameters of the
interface selected as
Leader
determines the behaviour of the group.
