Re: [openstack-dev] [neutron] Neutron Port MAC Address Uniqueness

[Anil Rao]

Hi,

My (original) question regarding the uniqueness of Neutron port MAC addresses 
didn't concern SR-IOV support or vendor NICs. It was simply about the behavior 
w.r.t. virtual networks. I believe Armando has confirmed what I had been 
suspecting.

Thanks,
Anil

That was my feeling Moshe, thanks for checking.

Anil, which card and drivers are you using exactly?

You should probably contact your card vendor and check if they have a fix for 
the issue, which seems more like a bug on their implementation of the embedded 
switch, the card or the driver.

Best regards,
Miguel  Ángel.

Re: [openstack-dev] [neutron] Neutron Port MAC Address Uniqueness

[Moshe Levi]

Hi Anil,


I tested it with Mellanox NIC and it working

16: enp6s0d1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode 
DEFAULT group default qlen 1000 

link/ether 00:02:c9:e9:c2:12 brd ff:ff:ff:ff:ff:ff  


vf 0 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto  


vf 1 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto  


vf 2 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto  


vf 3 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto  


vf 4 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto  


vf 5 MAC fa:16:3e:0d:8c:a2, vlan 192, spoof checking on, link-state enable  


vf 6 MAC fa:16:3e:0d:8c:a2, vlan 190, spoof checking on, link-state enable  


vf 7 MAC 00:00:00:00:00:00, vlan 4095, spoof checking off, link-state auto  
 

I guess the problem is with the SR-IOV NIC/ driver you are using maybe you 
should contact them

Miguel, 

I talked to our driver architect and according to him this is vendor 
implementation (according to him this  should work with  Mellanox NIC) I need 
to verify that this indeed working. 
I will update after I will prepare SR-IOV setup and try it myself.

@moshe, any insight on this?

I guess that'd depend on the nic internal switch implementation and how the 
switch ARP tables are handled there (per network, or global per switch).

If that's the case for some sr-iov vendors (or all), would it make sense to 
have a global switch to create globally unique mac addresses (for the same 
neutron deployment, of course).

hi Armando
I think this feature causes problem in sriov scenario, since sriov NIC 
don't support the vf has the same mac,even the port belongs to the different 
network.

[openstack-dev] [neutron] Neutron Port MAC Address Uniqueness

Is the MAC address of a Neutron port on a tenant virtual network globally 
unique or unique just within that particular tenant network?
