Note: Only one LACP system priority can be set on a Matrix DFE Series or N-SA device, using
either the set lacp asyspri or the set port lacp commands.
Notes: At least two ports need to be assigned to a LAG port for a Link Aggregation Group to form
and attach to the specified LAG port. Matrix DFE-Gold Series devices allow a maximum of four
ports per aggregator.
The same usage considerations for dynamic LAGs discussed on page 4-3 apply to statically
created LAGs.
