sflow - IPv6

Dear All,

 

 

I am using BIG-IP version 13.1.0.5 as sflow source. As sflow collector I configured "elastiflow" version 3.4.1 on top of an ELK stack. On BIG-IP I configured one receiver. At "System ›› sFlow : Data Sources : HTTP" I see a lot of virtual server configured. There are for IPv4 and IPv6 servers. When I use "kibana" (GUI) I see only IPv4 clients but no IPv6 traffic coming from BIG-IP.

 

So currently I do not know is this an issue of BIG-IP or is this problem related to ELK with "elastiflow".

 

I sampled sflow traffic with tcpdump. But I can't see any IPv6 addresses with Wireshark. Any ideas how to verify where is the bug or how to fix it ?

 

Kind regards
