If you ever need to pull individual statics for vLAN Traffic on a VMNIC. You need to access the esxcli command for a quick way to see the data.
Access the the ESXi host via SSH.
Then we need to enable statistic collection on the NIC, so run the command to enable the stats on vmnic0
esxcli network nic vlan stats set -e true -n vmnic0
This has enabled stats on this nic, now run this command to get the per vlan Info
esxcli network nic vlan stats get -n vmnic0
This will return a list of traffic on per vlan basis
VLAN 0 Packets received: 3274 Packets sent: 24 VLAN 400 Packets received: 14334203 Packets sent: 12547 VLAN 500 Packets received: 3330475941 Packets sent: 12548751 VLAN 800 Packets received: 538680670 Packets sent: 6564646
Don’t forget to disable the collection once you have finished troubleshooting
esxcli network nic vlan stats set -e false -n vmnic0
