Hi,
I want to test VPP NAT plugin performance in NAT44 dynamic translations mode
while supporting ipfix logging. (with 4 10gb ethernet interface , 40 CPU core
and 40gbps throughput)
based on VPP/NAT wiki page I used following configuration :
unix {
nodaemon
log /var/log/vpp/vpp.log
full-coredump
cli-listen /run/vpp/cli.sock
gid vpp
interactive
exec /root/vpp.cmd
}
api-trace {
on
}
api-segment {
gid vpp
}
cpu {
main-core 41
workers 40
}
dpdk {
dev default {
num-rx-queues 40
num-tx-queues 40
}
## Whitelist specific interface by specifying PCI address
dev 0000:04:00.0
dev 0000:04:00.1
dev 0000:07:00.0
dev 0000:07:00.1
dev 0000:21:00.0
dev 0000:21:00.1
dev 0000:24:00.0
dev 0000:24:00.1
num-mbufs 1000000
socket-mem 16384,16384
}
heapsize 90G
nat {
translation hash buckets 344827
translation hash memory 3498275862
user hash buckets 17241
user hash memory 93103448
max translations per user 5000000
}
and this startup commands :

set int state TenGigabitEthernet4/0/1 up
set int state TenGigabitEthernet7/0/0 up
set int state TenGigabitEthernet7/0/1 up
