→ Depending on selection-criteria setting either the sub-group with the highest number
of eligible links or the sub-group with the highest aggregate weight of all eligible
members is selected first.
→ If multiple groups satisfy the selection criteria, the sub-group being currently active
remains active. Initially, the sub-group containing the highest priority eligible link is
selected.
→ Only links pertaining to a single sub-group are active at any time.
→ An eligible member refers to a LAG member link which can potentially become
active. This means it is operationally up, and if the slave-to-partner flag is set, the
remote system did not disable its use (by signalling stand-by).
• The selection algorithm works in a reverting mode. This means that every time the
configuration or status of any link in a LAG changes, the selection algorithm is re-run. In
case of a tie between two groups (one of them being currently active) the active group
remains active (no reverting).
