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.
