Brian, I appreciate the explanation. I figured it was
related to Bc but I was having a hard time finding an
official answer anywhere on Cisco's site.
So, technically, you could fragment to a byte count
even smaller than Bc as long as it is not smaller than
the frame length for the realtime traffic you are
trying to minimize latency for...right? But, setting
it to Bc/8 seems to be the most logical and accepted
practice.
