I am pinging from one of the Juniper L3 interfaces to another with a rapid ping count of 10000 packets. It's a direct 100G optical connection and I am seeing 10-15 packets being dropped by the end of the ping test. If I do the same test connecting back to back on the same device, I don't see any drop at all. The results would be 10k packets sent and 10k packets received. I haven't really changed the cable or transievers between the tests. Why are the packets getting dropped?
