 Packets are never delivered out a many hook that is down.
 How a link is determined to be up or down depends on the node's
 configured link failure detection algorithm.

+Before an interface or link can be plumbed into a group, its status
+must be marked as being
+.Dq up .
+This is normally setup during the initial boot stages by
+.Xr rc.conf 5 . 
+It is also possible to change an interfaces status to

 More transmit and link failure algorithms should be supported.
 A good candidate is Cisco's Etherchannel.
