A bit of a noob question, but I can't seem to google (or bing) an answer.
In the switching world (where I have more experience), if I create a bundle of 5 x 1Gb connections in an LACP port channel, I get 5Gb of bandwidth, but none of the individual 'conversations' can be more than 1Gb.    
I am now looking at creating a Port Channel group between an MDS9148 and and MDS9134. If I bundle 5 of the 4Gb connections, I presumably get 20Gb of bandwidth. What I can't seem to find an answer on, is am I limited to 4Gb conversations again, or can a single source/destination pair use all 20Gb of the bandwidth?
