Dear all,

I am trying to enable IPFIX export for both IPv4 and IPv6.

Here my startup-config for VPP 21.10 running in QEMU CentOS 8 VM

set interface state GigabitEthernet0/5/0 up
set interface ip address GigabitEthernet0/5/0 10.2.2.2/24
set interface ip address GigabitEthernet0/5/0 2001:db8:2::2/64
set ipfix exporter collector 10.2.2.1 src 10.2.2.2 template-interval 20 path-mtu 1450
flowprobe params record l2 l3 l4 active 20 passive 120
flowprobe feature add-del GigabitEthernet0/5/0

With this config only flowprobe-ip4 feature set

vpp# show interface features GigabitEthernet0/5/0
Feature paths configured on GigabitEthernet0/5/0...
ip6-output:
none configured
ip4-output:
flowprobe-ip4

If I try to add ip6 this command failed

vpp# flowprobe feature add-del GigabitEthernet0/5/0 ip6
flowprobe feature add-del: Interface has enable different datapath ...

Only IPv4 shown in flowprobe table

vpp# show flowprobe table
Dumping IPFIX table
0/2 00:0c:29:d3:5a:02 00:16:3e:00:00:02 10.2.2.2 -> 10.2.2.1 1 0 0

If I change startup-config with

flowprobe feature add-del GigabitEthernet0/5/0 ip4 ip6

then only flowprobe-ip6 feature added

vpp# show interface features GigabitEthernet0/5/0
Feature paths configured on GigabitEthernet0/5/0...
ip6-output:
flowprobe-ip6
ip4-output:
none configured

vpp# flowprobe feature add-del GigabitEthernet0/5/0 ip4
flowprobe feature add-del: Interface has enable different datapath ...

vpp# show flowprobe table

Is it possible to setup IPFIX export for both IPv4 and IPv6?

Thanks
