Hi All,
My system configuration is
==>#. SuperMicro 1U
- BIOS: 1.0a
- Processor: Intel(R) Xeon(R) CPU D-1540 @ 2.00GHz
- Onboard NIC: Intel(R) X552/X557-AT (2x10G)
- Firmware-version: 0x800001cf
- Device ID (PF/VF): 8086:15ad /8086:15a8
- kernel driver version: 4.2.5 (ixgbe)
I am working on DPDK 16.04 & pktgen 3.0.0 version.
My intention is to test flow director based on just destination IP. It
means, i will use test-pmd and configure flow director and fdir mask, from
pktgen i will send packet and check if packets are going to right queue or
not.
Here is the procedure, that i follow.
1. I run testpmd
* ./testpmd -c 0xffff -n 4 -- -i --portmask=0x3 --nb-cores=5
--disable-link-check --rxq=5 --txq=5 --pkt-filter-mode=perfect*
2. executed command "*port stop all*"
3. After that added fdir mask
*flow_director_mask 0 mode IP vlan 0 src_mask 0.0.0.0 0:0:0:0:0:0:0:0 0x00
dst_mask 255.255.255.255 0:0:0:0:0:0:0:0 0x00*
4. Again executed command "*port start all*"
5. Now i added flow director filter.
*flow_director_filter 0 mode IP add flow ipv4-udp src 0.0.0.0 0000 dst
66.66.66.66 0000 tos 0x00 ttl 0x00 vlan 0 flexbytes (0x00,0x00) fwd pf
queue 4 fd_id 4*
6. after that "*start*"
---
7. On Pktgen side.... i just change destination Address to *66.66.66.66*,
protocol to *UDP* and issue command start 0.
---
Result
8. But instead of packet to queue 4, packets are going to queue 0.
