Hi All.
This is the first time that I have written here, so I hope that I am using it correctly.
I have a cisco WS-C2960S-24TS-L switch with IOS c2960s-universalk9-mz.152-2.E9.bin with all ports in use and passing traffic correctly.
Ports G1/0/4 and G1/0/11 are the only ones in Vlan 100 and are connected to two Linux servers using DPDK.
If I connect the two servers back-to-back the traffic passes without packet loss (1Mbps), but if I connect them through the switch the traffic has packet lots (5% packet loss).
If I activate the spanning-tree debug, the only thing that shows is the following:
If the images are showing some event that should not happen, please help me to know how I can configure the switch or switch ports to avoid this situation. I get ideas of all possible options. Thank you so much.

5% loss packet that OK why you think it high loss rate?

Hi, thank you for your interest. During 48 hours, I am passing 2000 packets/s with fixed datagram length of 40 bytes and I have a "Packet loss ration" = 4e-4 and I need it to be at least 8e-7

Hi. some additional comments. The switch in total on the other ports is passing 30Mbps & 4000pps (aggregate throughput).
In ports G 1/0/4 and G1/0/11 only 1Mbps is passing (2000 packets/s with fixed datagram length of 40 bytes); For a switch with GigabitEthernet ports to pass little traffic as 1Mbps between 2 ports and lose 5% is too high.
