[Intel-wired-lan] Traffic not passing for VLAN ID >= 32 on the I350 SR-IOV enabled NIC

[Intel-wired-lan] Traffic not passing for VLAN ID >= 32 on the I350 SR-IOV enabled NIC

[Yuvaraj Ranganathan]

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.

[Fujinaka, Todd]

Can you please file this through your company contact? I think you have very specific requirements that we can't discuss on a public mailing list.

You've already reported this internally, and you've mailed this to two different mailing lists. This just delays the issue so please go through the internal route.

[Intel-wired-lan] [E1000-devel] Traffic not passing for VLAN ID >= 32 on the I350 SR-IOV enabled NIC

[Laurent Dumont]

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?

[Intel-wired-lan] [E1000-devel] Traffic not passing for VLAN ID >= 32 on the I350 SR-IOV enabled NIC

[Yuvaraj Ranganathan]

Hi Laurent,

Thanks for your help.

Below is the information of SR-IOV interface, where VF 2 is directly mapped to VM interface.

root at 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 at 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.

[Intel-wired-lan] [E1000-devel] Traffic not passing for VLAN ID >= 32 on the I350 SR-IOV enabled NIC

[Laurent Dumont]

Strange!

Sorry, not sure what else to validate. I figured you might have been using
vlan filters on the VF directly but you see to use them as bare VF.

With a vlan specified at the VF level, it would have shown something like
vf 19 MAC fa:16:3e:d3:f7:f0, vlan 65, spoof checking on, link-state auto,
trust on

I do wonder if there is a vlan limit on the VF side. 4096 is a IEEE
standard max for VLANs because it's a 12 bit field in the ethernet frame
but it could be lower for the SRIOV part.

Can you try vlan ID 60 to 91?
