Re: Re: How should I use the ipoibd daemon from Mellanox Openstack Havana repo with SR-IOV?

Hi Erezsh

disabling namespaces it works. This is the configuration created by ipoibd

[root@n02 ~]# tail /sys/class/net/eth2/eth/{slaves,vifs}

==> /sys/class/net/eth2/eth/slaves <==

ib0.8002.1

ib0.8002.2

ib0.8001.1

ib0.8001.2

ib0.8001.3

ib0.8001.4

ib0.8002.3

ib0.8002.4

ib0.8001.5

ib0.8001.6

==> /sys/class/net/eth2/eth/vifs <==

SLAVE=ib0.8002.1 MAC=00:02:c9:50:60:8d VLAN=2

SLAVE=ib0.8002.2 MAC=N/A               VLAN=N/A

SLAVE=ib0.8001.1 MAC=00:02:c9:50:60:8d VLAN=1

SLAVE=ib0.8001.2 MAC=N/A               VLAN=N/A

SLAVE=ib0.8001.3 MAC=7a:e6:b9:30:eb:c1 VLAN=1

SLAVE=ib0.8001.4 MAC=fa:16:3e:04:4c:f7 VLAN=1

SLAVE=ib0.8002.3 MAC=82:4d:52:88:65:da VLAN=2

SLAVE=ib0.8002.4 MAC=fa:16:3e:b3:f6:a3 VLAN=2

SLAVE=ib0.8001.5 MAC=86:ac:55:a8:f0:c9 VLAN=1

SLAVE=ib0.8001.6 MAC=fa:16:3e:52:32:68 VLAN=1

I have just 2 questions:

• why does ipoibd enslave some clones with the same MAC address (00:02:c9:50:60:8d) of the eIPoIB interface (eth2)? (the kernel module always logs: eth2.[12]: received packet with own address as source address)
• What are the interfaces ib0.8001.2 and ib0.8002.2 used for?

Thanks
