OVS 3.1 Mirror shows no statistics when mirroring DPDK ports

Hi all,

I’m trying to create a mirror in OVS 3.1.0057. I have a bridge br-inside with two DPDK ports (p1 and pf1hpf) and I want to mirror the traffic to a normal port en3f0pf0sf0 on another bridge br-mirrorI.

I created the mirror like this:

ovs-vsctl -- --id=@p1 get port p1 -- --id=@p2 get port pf1hpf -- --id=@m create mirror name=m1 select_dst_port=@p1 select_src_port=@p1,@p2 output-port=@p2 -- set bridge br-mirrorI mirrors=@m

The mirror was created successfully:

_uuid               : fd21f823-9d68-44ed-a5d1-821ddd7115ee
external_ids        : {}
name                : m1
output_port         : 03ba8c56-5d8d-49b6-8cb6-1279270a8112
output_vlan         : []
select_all          : false
select_dst_port     : [4072c5a7-22d1-40db-94fe-b0d2d613730f]
select_src_port     : [03ba8c56-5d8d-49b6-8cb6-1279270a8112, 4072c5a7-22d1-40db-94fe-b0d2d613730f]
select_vlan         : []
snaplen             : []
statistics          : {}

The problem is that the mirror shows no statistics and doesn’t seem to capture any traffic.

Here’s the current bridge setup:

It looks like the mirror is created, but nothing is being mirrored. Any ideas on what might be wrong or how to get it working?

Thanks!

I use this format:

ovs-vsctl – --id=@p1 get port [dst-port] \

-- --id=@p2 get port [src-port] \

-- --id=@m create mirror name=[mirror-name] select-dst-port=@p2 select-src-port=@p2 output-port=@p1 \

-- set bridge [bridge-source] mirrors=@m
