Aggregation Mode and Switches

If your aggregation topology involves connection through a switch, you must note whether the switch supports the link aggregation control protocol (LACP). If the switch supports LACP, you must configure LACP for the switch and the aggregation. However, you can define one of the following modes in which LACP is to operate:

• Off mode – The default mode for aggregations. LACP packets, which are called LACPDUs are not generated.

• Active mode – The system generates LACPDUs at regular intervals, which you can specify.

• Passive mode – The system generates an LACPDU only when it receives an LACPDU from the switch. When both the aggregation and the switch are configured in passive mode, they cannot exchange LACPDUs.

See the dladm(1M) man page and the switch manufacturer's documentation for syntax information.
