hi Neale,
we are expecting to be able to handle different MAC addresses for
VLAN interfaces. This feature seems to be not available in VPP as of
now.
we also tried looking for possible work around, which were dead ends
as of now. Please let us know if we agree to this as something that
can be done for VPP, we can work on this and contribute if useful.
please share your inputs
Regards,
Prabhjot

Hi Neale,
Thanks for the reply.
A physical interface could have multiple Vlan interfaces and I want traffic
originating from Vlan interface to have user defined Mac address rather
than parent's Mac address.
In Linux we have this privilege to associate Mac addresses to Vlan
interfaces using ifconfig.
In Linux, we use vconfig to create Vlan interface and then we could
leverage ifconfig to configure our own Mac address on the Vlan interface.
Could we have something similar in VPP?
Best Regards,
Omer

Hi Omer,
You can set the MAC address of a ‘host’ interface when it is created:
create host-interface name <ifname> [hw-addr <mac-addr>]
you can also change it after creation:
set interface mac address <interface> <mac-address>
but you cannot set the MAC address of a VLAN interface. A VLAN interface
will always have the same MAC address as its parent/physical interface.

Neale

Hi,
I am trying to form an ecmp between Vlan interfaces. Traffic coming with
IP 1.1.1.5 would go through Vlan interfaces host-tap0.1 and host-tap1.1
forming ecmp.
ip route add 1.1.1.5/32 table 3 via 1.1.1.5 host-tap0.1
ip route add 1.1.1.5/32 table 3 via 1.1.1.5 host-tap1.1
set ip arp host-tap0.1 1.1.1.5 02:00:00:00:00:02
set ip arp host-tap1.1 1.1.1.5 02:00:00:00:00:02
ip route add 1.1.1.5/32 table 5 via 1.1.1.5 host-tap2.1
ip route add 1.1.1.5/32 table 5 via 1.1.1.5 host-tap3.1
set ip arp host-tap2.1 1.1.1.5 02:00:00:00:00:01
set ip arp host-tap3.1 1.1.1.5 02:00:00:00:00:01
However traffic flows having Source Mac addresses as that of respective
Vlan interfaces. Is there any way I could set Vlan interfaces with my own
desired Mac Addresses, so that the traffic has user defined Mac addresses
as Source Mac addresses.
Thanks.
Best Regards,
Omer Majeed
