Haha, silicon valley history has shown that it doesn't matter who came out with the idea first, but it's about who did it BEST. It's cool that companies try to top each other, who cares who came out first or who copies who! Let them copy! Im not agreeing with you that Cisco imitated Arista, who know who imitated who, and who cares?! First, a lot of Arista people used to work at Cisco. Secondly, at the end of the day, we the customers are the ones that win.
