[c-nsp] Is the 6704 really as terrible as everyone says?

[cisco-nsp]

I've experienced output queue drops on interfaces that have high-bandwidth/bursty traffic patterns (e.g., multicast traffic being replicated to multiple VLANs on a trunk).  For other scenarios, where 1Gb won't do the job, but I don't need anywhere near 10Gb, they work fine.  If I could do it all over again, I'd just get the 6708s, but it sounds like the 6704s would work fine in your scenario.

I've read several posts on here that lead me to believe that the WS-6704-10G is essentially the worst linecard ever produced.

The problem is, I only need 2 ports of 10G and just to replace 2x1Gbps uplinks that almost never get anywhere near their line rate capacity.

If they are really, really, awful. I will probably just end up getting a 6708 for this particular switch, but I would rather not considering the huge price difference.

Currently I am using the 1G ports off of the Sup720 as the uplink, and I hear those have awful buffers as well.

So when upgrading from the ports on the Sup720 to a 6704, is that still a bad move?

thanks,
-Drew
