One added note is that there are port pairs on the 6708 line card and those port pairs are 16G to connect to the next layer ASIC.
That means that a pair of ports can only handle 16G of traffic where they could receive or send 20G.

See my post from 2011.

Exactly. Inside fabric channel they use local switching and never leave linecard. Between fabric channels (Same card or not) they use fabric.
