FreeBSD Ethernet Port Bonding

After reading about FreeBSD aggregation we think we are set but it's still not clear to me. Switch is a Cisco 2960S (software 15.x), Client is a Mac Pro running Mavericks. I don't know if the BSD internals are the same, but don't expect they have changed much over the years. Mac Pro is a medical clinic client's server (required for their application). Below is what I’m seeing on my switch and according to the article, one sets the switch ports to active, then the flags show the peer as SA, meaning the peer is Active thus the contradiction. If the switch is set to active, I would expect the peer to be passive.
