BIG-IP Virtual Edition (VE) cannot drive multiport Mellanox ConnectX-3 cards without disabling the second interface on the host. When creating a virtual function, BIG-IP will see two interfaces, but only one may function, and the other may be down and have the wrong MAC address.
The second interface within BIG-IP system may not come up correctly and may report the wrong MAC address. Only the first interface works properly.
BIG-IP VE running under KVM with an SR-IOV virtual function from a multiport Mellanox ConnectX-3 adapter.
Explicitly specify which physical interface the virtual function should belong to. This is done on the KVM host below BIG-IP, by adding the following to /etc/modprobe.d/mlx4_core.conf and rebooting the host: options mlx4_core num_vfs=4,4,0 port_type_array=1,1 That creates 4 VFs from each port of a dualport card, and they can then be assigned to BIG-IP.
