Well, these is lagg interfaces:
lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
         options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
         ether 00:30:48:67:d4:68
         media: Ethernet autoselect
         status: active
         laggproto lacp
         laggport: em2 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>
         laggport: em0 flags=1c<ACTIVE,COLLECTING,DISTRIBUTING>

There is no baudrate on them. But they are really high-speed however.
