Hey All,
I posted an earlier question around applying CoS markings using NetIOC or at the distributed port group layer. I assume that NetIOC can only mark CoS values and not DSCP values? Will assume this until I hear otherwise. Right now the customer's VMware environment should be marking traffic using NetIOC when traffic leaves the ESXi host. I am trying to verify this occurs and need some ideas on the easiest way to do so. I have been using the VMware tool pktcap-uw that is included with ESXi 5.5 and it looks like it should be able to capture packets with the information that I want to see in Wireshark. The problem though, I am unable to see any packets that include dot1q tags and in turn the CoS markings. Does anyone have an alternate method to capture traffic? I want to check NFS, vMotion and VM traffic to confirm CoS markings are present.
Thanks!
