Subject: [dpdk-users] testpmd: Flow Director
Date: Fri, 8 Feb 2019 20:01:53 +0100 [thread overview]
Message-ID: <CAD=oxmkYsvcwmRGUif8SE9UOJT1V4zE4u-DVQcTeKtsWwJQTKA@mail.gmail.com> (raw)
Hello,
I try to configure FD in testpmd app (PDK_v18.11.0_LTS) to identify
TCP flows (based on destination IPv4 addr and destination TCP port)
and route them to specific queues. I start the testpmd on the
following way:
testpmd \
-c 0xf \
-n 3 \
-- \
--port-topology=chained \
--rxq=8 \
--txq=8 \
--interactive \
--forward-mode=rxonly \
--disable-rss \
--pkt-filter-mode=perfect
then:
set verbose 5
set fwd rxonly
port stop 0
flow_director_mask 0 mode IP vlan 0x0 src_mask 0.0.0.0
0000:0000:0000:0000:0000:0000:0000:0000 0x0000 dst_mask
255.255.255.255 0000:0000:0000:0000:0000:0000:0000:0000 0xFFFF
port start 0
flow_director_filter 0 mode IP add flow ipv4-tcp src 0.0.0.0 0 dst
192.168.10.2 9001 tos 0 ttl 64 vlan 0x0 flexbytes (0x08,0x00) fwd pf
queue 1 fd_id 1
show port fdir 0

on other box (192.168.10.1):
telnet 192.168.10.2 9001
which gives the following messages in testpmd app:

Pkts are routed to queue id 0, instead 1. Any ideas?
