Answer 1

I found these notes from a network engineer.
"you can not use the dladm command on any interfaces that are plumbed up. You have to, "ipadm delete-ip aggrX" before you can use dladm set-prop on aggrX. "
"Do not  change MTU on a configured interface, this has to be done as the first step before the aggr is created."
