I/O Aggregator (IOA) Programmable MUX (PMUX) Mode

IOA PMUX is a mode that provides flexibility of operation with added configurability. This

involves creating multiple LAGs, configuring VLANs on uplinks and the server side, configuring

data center bridging (DCB) parameters, and so forth.

By default, IOA starts up in IOA Standalone mode. You can change to PMUX mode by executing
