VF MAC is not assigned as expected

[idata]

Hi,

My server is running RedHat 7.1.

ixgbe - 4.0.1-k-rh7.1

ixgbevf: 2.12.1-k

igb:5.2.13-k

igbvf: 2.0.2-k

I want to assign the fix MAC to VF, so I configure like this

# cat /etc/rc.d/rc.local

echo 1 > /sys/class/net/bi0/device/sriov_numvfs

ip link set bi0 vf 0 mac 00:6f:2a:01:b0:00

echo 1 > /sys/class/net/fi0/device/sriov_numvfs

ip link set fi0 vf 0 mac 00:6f:2a:01:f0:00

While after system reboot, the MAC of VF fi0 is not expected. (The VFs are loaded in Host OS.)

Do you have any idea?

Hi,

The adapters are:

bi0 - Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)

fi0 - Ethernet controller: Intel Corporation 82599EB 10-Gigabit KX4 Network Connection (rev 01)

Hi Nicole.Z,

Please provide Linux Host kernel log and VM (Guest) Linux kernel Log. The Linux kernel log can be found at /var/log/messages.

Looking forward to your reply.

Thanks,

Hi,

Sorry for the late response.

Actually there is no VM is running. The VF interfaces are loaded in host OS.

Attached the /var/log/messages.

Hi Nicole.Z

Further checking ,the adminstrator set VF MAC address then later on Network Manager tried to set VF MAC address that was disallowed then VF has to be reset. Since Intel PF and VF drivers has a built in security feature called administrative assignment of VF MAC address. If the server administrator assigns a VF MAC address from the HOST any subsequent changes to the VF MAC address are disallowed.

Thus please try disabling the network manager.

Hi,

I tried to disable NetworkManager, but after reboot the VFs never boot up, and MAC are still unexpected. Tried to restart network service, it didn't help.

# systemctl status NetworkManager ! !

NetworkManager.service - Network Manager

Loaded: loaded (/usr/lib/systemd/system/NetworkManager.service; disabled)

Active: inactive (dead)
