Ipv6 flow-accounting can't collector by Netflow v9

interface ethernet eth0 address 2001:100::254/64
interface ethernet eth1 address 2001:200::254/64
interface ethernet eth1 address 172.16.23.1/24
system flow-accounting interface eth0
system flow-accounting interface eth1
system flow-accounting  netflow server 172.16.23.254 port 2055
system flow-accounting  version 9
system flow-accounting syslog-facility daemon

sudo tcpdump -i eth0 --> can see heavy ipv6 traffic, but show flow-accounting can’t see any ipv6 flow
show flow accounting --> just only ipv4 flow, not any ipv6 flow

Can anyone help me?

Hi I can confirm that.

even in raw data, i don’t see ipv6 traffic.

sudo /usr/bin/pmacct -p /tmp/uacctd.pipe -s

I can’t test if is send correctly to a remote server. But can test this tomorrow.

Which vyos version do you use?

@rob, @bee, collecting of IPv6 traffic did not exist in VyOS. We prepared the fix for this problem.
Please, use the Phabricator task for future tracking: https://phabricator.vyos.net/T1613

my vyos version is VyOS 1.2.0-rolling+201905280337
