In case if you need QSFP+ ER optics then I have been using Innolight
optics especially, the 40G LR and PSM in s4810/Z9000 switches.

Try the Ubuntu Image which is all pre-configured, saves lots of time. I
am using it under a CentOS KVM installation.
Once you are logged in then go to /opt/librenms and issue 'git pull' to
get the latest updates.
The only caveats you might come across is the size of disk space which
is 10GB at th
For WS 6704 (with DFC3B), I was able to go close to 9Gbps per port
across the bus when using Iperf and jumbo frames. Single port on each of
the bus gives you line rate of 9.9Gbps.

Iperf, netperf are good tools for bandwidth measurements (both udp and
tcp, uni and bidirectional). You can find more from Caida.

It should not work as both have different encoding and no of wavelengths.

In order to use SFP+ from other vendors in Arista, you need to get them
enabled first.
