Hello, all!
Have below scheme:
When generate 3,2 Gbps AppMix traffic - all work fine.
When generate 2Gbps of HTTP traffic - all work fine.
When increase throughtput of HTTP traffic to 2,2Gbps - packets drops appear on LAG.
But ports utilization at that moment is not so big:
Packets is different and not so little:
HTTP is simple:
Client GET -> Server Request with 1024k page
Help please to investigate reason of drops.
Thank you!
