[AusNOG] 10GBs

[Robert Hudson]

There is no trial and error. Start at Layer 1, and work up the stack.

Correct setup and good logging should resolve it.

There are lots of potential issues. You can cut some of them down
immediately by selecting hardware on the hypervisor supplier's HCL - they
should have good drivers for the 10Gbps NICs at that point.

Speed/duplex, frame size, etc, all need to be consistent across the entire
environment. Get wireshark or an equivalent involved (using a mirror port
if necessary).

If your hardware and software are all under full support, involve your
vendors in the issue.
