Hello 

My Dell R440 server is using BCM57412 Netxtreme-E 10Gb RDMA Ethernet Controller Dual Port.
This interface is for both 1G/10G. These were recognized as vmnic4 and vmnic5.
For example vmnic4,
My problem is that the mirroring traffic on the switch is not normally checked by tcpdump on the virtual machine.

The switch passing traffic has 10.x.x.x band and 172.16.x.x band.
I set 10.x.x.21 as my ESXi IP and the traffic my PC communicates with 10.x.x.21 is confirmed by tcpdump on the Mirror4 portgroup.
However, traffic in the 172.16.x.x band is not checked.

So, I tried to collect traffic of vmnic4 (Mirror4 portgroup and port connected to vSwitch4) in ESXi shell with pktcap-uw command.
Traffic in the 172.16.x.x band was collected.

On vmnic2 using UTP port, 172.16.x.x band traffic is seen by tcpdump as intended.

As a result, traffic sent from the switch to vmnic4 is not normally delivered to the virtual machine. this is my conclusion

The physical interface was recognized as bnxtnet and the driver version is as follows.
216.0.50.0-44vmw.703.0.50.20036589
216.0.58.0-23vmw.703.0.50.20036589

The vNICs are the same I tried with E1000 and VMXNET3.

There is no difference in the settings of vSwitch2 connected to vmnic2 and vSwitch4 connected to vmnic4. Indiscriminate mode was also accepted.

Has anyone had the same trouble as me?

Thanks for taking the time to help.

thank you
