In attempting to operationalize the ACX7100 I have run into quite a few challenges with the platform once I stray outside of traditional routing and switching.  The EVPN instances seem to have quite a few caveats and things like CFM and RFC2544 traffic generation.  Many of the show commands don't seem to work, many of the counters either don't work or update slowly (like I run the command to show CFM messages and it says it sent 100 then I run it again a couple seconds later and it says 10000 sent then a couple seconds later it says 1000000 sent) this with a periodicity of 1 message per second.
