Hi,
Our topology is :
Spirent <->Ubuntu 12.04 Server <-> our application within VM where VF is directly attached.
on VF interface , created vlan interface and spirent has also also vlan interface.
NIC : Intel 82599 ES
IXGBE Version : 3.15.1-k
IXGBEVF driver version :2.7.12
By default, VF is not receiving any packet , even ARP Packet. After configuring vlan filtering from VF, it gets packet with stripped vlan tag.
There are couple of questions :
1. Is there any way to configure from VF, so PF doesn't filter any vlan , simply pass traffic to VF ? I checked Spec , it mentions about this and by default, it is enabled.
2. How to avoid stripping of vlan tag ? I changed accrording to spec but it stopped receiving any vlan packet.
3. Even I tried to add all vlans(1 to 4094) , but it doesn't work. it looks like only fixed entries(most likely 8) can be added .
Please let me know how to fix this problem from VF side, can't change PF code.
Thx,
Atulya
