Hello everyone,
I'm trying to test the performance of Multicore at VPP,
The Topology of test is simple,
TG - DUT - TG
- The Specification of DTU -
CPU Intel(R) Xeon(R) CPU E5-2699A v4 @ 2.40GHz
NIC XL710 40GbE QSFP+
Linux version Ubuntu 16.04.3 LTS
VPP Verion v18.07.1-release
DPDK Version DPDK 18.05.0
test Traffic Bi-direction traffic(40Gbps)
-----------------------------
There is no problem until the 2Core/port.
It will be a bug, scaleout from 3Core/port.
The One port is not working.
Please look at the example below.
In terms of "show interface", the RX packets count of one port is not
counted.
but,
In term of "show hardware-interfaces",
All ports receive packets.(RX packets count is counted.)
Then TX packets count is half of the rx packets count.
Do you have a solution to this problem?
example 4Core/port>>
<interface status>
vpp# show interface rx-placement
