Hi, I do suggest you go over EN offering with a fine tooth comb.
We experienced a whole lot of issues with 6 x650: . from hardware licensing (start at shipping from the fab and not when the customers get them); . software licensing (have to license every box even the ones in the labs); . known eeprom defect limiting upgrade from XOS 12 to 15; . 1 vlan-translation causing all sort of head-aches with port-grouping (ether-channel); . EAPS packets being silently filtered out of VMAN's when you do not use the Core license; ( Undocumented and that is not acceptable when trying to transport customers owns EAPS traffic on their VLAN's ) . no VLAN flapping logging; Don't get me wrong, they are good campus switches... just not designed for "our" L2 Core purposes. And the Licensing is just an exercise in frustration. I can understand the business purpose, just not the way they go about doing it. As for L3 support, it is fine: . include IP tracking in VRRP with is a plus for us . Virtual Routers We don't need them for BGP and we do not have a MPLS network yet. As for the x670, maybe most of the hardware issue has been addressed, but I doubt the licensing and undocumented limitations is better. PS: We're using them (x650), and are planning to keep using/recommending EN products, but it did cost us a lot of man hours and un-planned crashes that could have been prevented with better documentation and support.
