Hi I have an application which is sending data(FAST) to from pc to HW. It works fine. However when I have this Z9100-on switch between HW and pc, the switch is stopping the data. I have tried various settings with flow control and storm control but it doesn't help.

If I print the 'show hardware drops interface' of the interface, I cans see that Ingress Drops,Packets dropped by FP, and Port bitmap zero Drops increase by for example 1000 if I send 1000 packets.

Do you have any tips how to fix this problem ? Is this a HW buffering issue. What can I do to fix this ?

Drops in Interface Hu ...:

 

Ingress Drops                 : 468574

PortSTPnotFwd Drops           : 0
IPv4 L3 Discards              : 0
Policy Discards               : 1864
Packets dropped by FP         : 131709
(L2+L3) Drops                 : 0
Port bitmap zero Drops        : 468574
Rx VLAN Drops                 : 21
