I think the main consideration is that HC is based on 64 bit counters, and the non HC is based on 32 bit counters. So for a high speed interface a 32 bit counter may roll over quite often. Using a 64 bit counter is more convenient in terms of not having to monitor for counter roll overs. The data in terms of packet counts should be equivalent.

It should be working now, we had to make an adjustment on a BGP peering with an upstream provider.
Please check the external connectivity now and let us know if all is ok for your slices.
Thanks,
Tom
Closing this issue since the FABRIC MASS dataplane link is back in service

@yoursunny Thanks for the nice testing table/results. We do have some links in the network which need to be set higher to allow hosts to use MTU of 9000. We need to do some more testing for all the links in the network to see if we can find a single value that works everywhere. We are also adding many new wide area links over the next month. So we will probably update the MTU settings across the network sometime in June. We will report back here on the forum with more details once we have made this change. For now, hopefully you can use MTU 8948 as you show in your table, until we make the change.
The MASS site/links should now support a host MTU of 8948. Please let us know if you still have issues with MASS node.
This work to add the new dataplane links to the FABRIC network topology is complete.
