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
. known eeprom defect limiting upgrade from XOS 12 to 15;
. 1 vlan-translation causing all sort of head-aches with
. 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.
Good luck with your project =D
