Hi NSP,
I configured IPFIX in juniper MX running 11.2 R3. I run wireshark in flow
collector where i m getting flows from the juniper router but all data are
showing "no template found"? What is the problem in this? I had a problem
This is normal and expected.
IPFIX/Neflow9 exporters only send the templates periodically. They are
not sent with every packet.
You need to leave your capture running for long enough that it:
1. Sees a packet with IPFIX/NF9 templates
2. Sees data packets referencing those templates
On other (non-JunOS) platforms, I have been able to trigger a template
export by making and then un-making a config change to the netflow
export that will affect the templates e.g. remove then re-add src/dst AS
number.
Many/most platforms have configuration for the interval to re-send the
templates; I think it is:
edit set service flow-monitoring version-ipfix template X
set template-refresh-rate [packets N | seconds Y]
