This read-only object is used to display whether the port participates in dynamic aggregator selection. The default will be static aggregation selection. static(0) - The port is involved only in static aggregation. i.e. the port can be a member of only the aggregation to which it is configured. dynamic(1) - The port participates in dynamic aggregation selection. i.e. the port will be a part of best aggregation selected based on System id and Admin key. This object is set to 'dynamic' once the port is configured as a default port of a port channel.
