Comcast Ethernet Feed

Fri Mar 30 01:47:30 UTC 2012

The GIGe is on-board with the NPE-G1 and from what I am told no bandwidth points to deal with .. the PA is in slot 4 with ZERO other traffic on that slot or the port, all other traffic that is of any real size is on the other two GIGE interfaces that are also on-board with the NPE-G1 blade.

How do you have the PA modules installed?  Layout can make a huge 
difference on those given the bandwidth points system.
