Doug, We've just finished some research into 10Gig + 40 to 100Gig Density mapping in Juniper. I'll collect my notes and send them to the list with my thoughts. Thank you, *Levi Pederson* Mankato Networks LLC cell | 612.481.0769 work | 612.787.7392 [log in to unmask] On Thu, Oct 27, 2016 at 2:07 PM, Doug McIntyre <[log in to unmask]> wrote: > On Thu, Oct 27, 2016 at 08:21:54AM -0500, Mike Horwath wrote: > > On Thu, Oct 27, 2016 at 08:06:45AM -0500, Jason Hanke wrote: > > > There aren't enough ports on the 4550 to swap it in we would need > > > two.
