Hardware; css106-5G-1S. Firmware: v2.5

I've looked at the documentation and the web interface, but can't seem to find any way of setting the per port cost. I my case, I have two paths running at the same speed between two css106 boxes, so speed doesn't differentiate them.

I would appreciate any pointers to where the info may be found. I've already done a search on this forum.

Thank You.
