Hi all,<br>
<br>
below are some interesting links concerning IEEE 802.3ad LACP in
CentOS6 &7 (RHEL7) respectively:<br>

I was just curious :)<br>
<br>
I'm well aware of what can be achieved with pure bonding setup.
But since this is the NOG group I wanted to learn is<br>
it at all possible to achieve something like that using HW
devices.<br>
<br>
Thanks for the info Boyan,<br>
