So, in summary: Your dropped packet counters are the ones to be looking at
as a measure of goodput, more than your utilization counters.
Indeed. Capacity upgrades are best gauged by drop rates; bit-rates without

Folks,
Please take a look at draft-iana-ipv4-examples. This draft discusses the
following subnet allocations:
- 192.0.2.0/24 (TEST-NET-1)
- 198.51.100.0/24 (TEST-NET-2)
- 203.0.113.0/24 (TEST-NET-3)
RFC 1166 allocates TEST-NET-1 for use in documentation. Because the
other two have been used in

Anyone seeing issues getting to level 3, att, or ntt? I seem to be
seeing packet loss going to level 3 mostly in LA.
I'm getting packet loss at xe-11-0-0.edge1.SanJose3.level3.net

If anyone has deployed VPC on the Cisco Nexus 5/7k platforms in a production
environment I'd appreciate knowing how you feel about it (off-list please).
This isn't a hunt for negative Cisco bashing, we're very interested in
deploying this feature and would like to know what new problems we
just spoke to level 3, they did have some latency issues in los

I've used Spirent, IXIA and Anritsu test gear and I prefer the Anritsu
