Hi Keith,
Sorry I forgot to mention earlier
I did create the veth pair using “ip link” and the other end is linked to a
network namespace using netns. I was able to create the host-interface on the
vpp cli using
sh-4.2# vppctl create host-interface veth0-craft0
sh-4.2# vppctl show int
Name Idx State Counter Count
host-veth0-craft0 1 down
local0 0 down
When I try to do the same thing using the python API I ran into issues
mentioned below.
I have reference the wiki page https://wiki.fd.io/view/VPP/Python_API
Thanks
Shravan

Check what the name of the system interface is:
ip -o a
We don't create the veth pair for you, so once you do this with "ip link" and
ostensibly move one end into a netns, the other end is the one you add to VPP.

Thanks Ole!
I did try it before. I ran into issues when I invoke the API.
>>> r = vpp.af_packet_create(veth0-craft0)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'veth0' is not defined
>>> r = vpp.af_packet_create('veth0-craft0')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: <lambda>() takes exactly 0 arguments (1 given)
>>> r = vpp.af_packet_create(1)
Traceback (most recent call last):

I am a python newbie, so please excuse my naïve question.
This is probably not a vpp issue. I must be invoking the Api wrong way.
Do you happen to know by any chance what is the right way to invoke it?
Thanks
Shravan

Looks like we're not quite consistent on naming.
It is this API you are looking for I think:
/** \brief Create host-interface
@param client_index - opaque cookie to identify the sender
@param context - sender context, to match reply w/ request
@param host_if_name - interface name
@param hw_addr - interface MAC
@param use_random_hw_addr - use random generated MAC */ define
af_packet_create {
u32 client_index;
u32 context;
u8 host_if_name[64];
u8 hw_addr[6];
u8 use_random_hw_addr;
};
Best regards,
Ole
