[c-nsp] 10G 6704 and 6708

Am currently using quite a few 6704's, some with DFC(at 3CXL spec), some
without.

Nothing fancy really going on, they just work, have some using CX4 and some
using long range fibre, of course we are on xenpaks rather than X2's with
the 6704.

The only issue i've had is a netflow bug when exporting from the DFC's
(CSCsq14299) but that got fixed in SRB4.

Haven't actually had one hit 10Gb yet so can't say how well they handle
congestion or really high traffic flows but certainly <5Gbs is no problem.

Hi,

im looking at 10G cards for 7600 with SUP720-3BXL (running SXF) and wanted
an opinion from the list

ive seen posts in archives and cisco datasheets and im aware of the
differences between the 6704 and 6708 (6708 comes with 3CXL, deeper buffers,
etc...). the port density on the 6708 (though not at line rate) is
attractive.

no fancy features or requirements here, just plain old lan switching

anyone cares to share experiences with these cards in production ?



Thanks,

anton
