Hi Laurent,
Thanks for your help.
Below is the information of SR-IOV interface, where VF 2 is directly mapped to
VM interface.
root@local-node:~# ip link show heth-0-1
5: heth-0-1: <BROADCAST,MULTICAST,ALLMULTI,PROMISC,UP,LOWER_UP> mtu 9192 qdisc
mq state UP mode DEFAULT group default qlen 1000
link/ether 58:00:bb:aa:ee:49 brd ff:ff:ff:ff:ff:ff
vf 0 MAC aa:81:c7:6f:b4:0a, spoof checking on, link-state auto, trust on
vf 1 MAC 16:26:97:40:0f:86, spoof checking on, link-state auto, trust on
vf 2 MAC 58:00:bb:aa:ee:60, spoof checking on, link-state auto, trust on
vf 3 MAC 22:28:fa:f4:68:1a, spoof checking on, link-state auto, trust on
root@local-node:~#
On configuring the VLAN >=32 on the VM interface and tried sending outgoing
traffic, there is no packet captured in tcpdump at SR-IOV(heth-0-1) interface.
In case of VLAN <= 31, the outgoing packet captured in tcpdump at heth-0-1
interface.
You help is always appreciated!
Thanks,
Yuvaraj.

SR-IOV enabled NIC
[External Email. Be cautious of content]
Can you show the output of
ip link show $SRIOV_INT_NAME_HERE
Are you seeing any traffic reaching inside the VM if you tcpdump there?

Hi Team,
With the SR-IOV enabled on I350 NIC which has 4 VF’s, on configuring VLAN ID
from range 1 to 31 on the VM interface, network traffic is fine and no issues.
When trying to create an interface with VLAN ID >= 32 on the VM, traffic is not
passing to that interface and as per HW specs, VLAN ID’s from 1 to 4096 are
supported.
VM’s interface is directly mapped to one of the VF on I350 NIC. I am using IGB
PF driver version 5.7.2(latest).
Could somebody please help!
Thanks in advance,
Yuvaraj.
