Packet drop


Userlevel 6
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!

Hello, Bastian!

After:
# disable flow-control rx-pause ports all
# disable flow-control tx-pause ports all

There is no any drops:
