As I said - niche market :-). Nothing wrong with that :-)

Are the F2 and M2 line cards closer or better than Arista?

When I was subcontracting they actually got my general contractor fired for oversubscribing the switch and not knowing the shared and dedicated 10gb ports rule :( the F2/M2 cards are a lot more competitive with Arista and Juniper's raw performance. Will Cisco have a few weird features some Satcomm backbone needs to segregate control frames? Perhaps... but THAT possibility is the niche - not the rule. > > thanks > > -----Original Message----- > From: Marko Milivojevic [mailto:markom_at_ipexpert.com] > Sent: Saturday, December 29, 2012 12:45 AM > To: Joseph L.
