Solaris 11 ipadm show-if disabled

Hi exports,

I have a T4 with 4 port internal NIC which 2 ports are active and, external one with 4 ports as well with only 2 ports active. So the total of the ports are 4 out of 8. I have created an link aggregation called gnic0 with ports net0, net1, net6 and, net7 in it. I also created a vnic1 over gnic0. here is what I see

all 4 ports are up and, running. right? but, is the below behavior normal?

 root@ap1g:~# ipadm show-if

net8       ip       ok       yes    --
net6       ip       disabled no     --          <------------ disabled??? why
net7       ip       disabled no     --          <------------ disabled??? why
net0       ip       disabled no     --          <------------ disabled??? why

when i do snoop of all of my NICs I see traffic on all the network.
My server is running on vnic1.

Please shed some light on this.
thanks a bunch
