6704 is not exactly 1:1, while 6708 is exactly 1:2. So if you stick play-doh on 4 ports in 6708 you have wire-speed card (FSVO wire-speed, I really hate the term though, I mean wire-speed surely has to mean overspeed of maxports-1 * maxportspeed?) Also as an interesting curiosity LAN cards prior to 6708 are slow to detect linedown, so if you're venturing inside the subsecond convergency world, it is relevant. > Paul > > > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf Of Gergely Antal > Sent: Tuesday, March 31, 2009 2:55 AM > To: Eric Gauthier > Cc: [email protected] > Subject: Re: [c-nsp] 10GE card for 7609 > > And also keep in mind that WS-X6708-10GE is a true line-rate card... > > Eric Gauthier wrote: > > Mark, > > > > I'm not sure if you have other 10g links, but keep in mind that Cisco > > has (at least) two 10g optics - Xenpak and X2 - that are not > intercompatible. > > I believe that the 6704-10ge uses Xenpak and the 6708-10gE, which is > > the "same" card but with 8 ports, uses X2.
