Hi,
We recently moved a machine from one part of our network to another,
requiring it to be re-imaged to fulfil some regulatory requirements.
Prior to the move, PF_RING in zero-copy mode worked fine for both
capture interfaces. After the move, our licence is no longer recognised,
and PF_RING zero copy mode operates in demo mode only.
The NIC is an Intel X710 device, and we were using PF_RING 7.4.0 running
i40e drivers. The OS was Centos 7.
The machine was re-imaged with a fresh copy of Centos 7, PF_RING 7.4.0
re-installed, and our existing licences re-applied to the usual
/etc/pfring/<mac> files.
Our PF_RING reports itself as 7.5.0.181221 according to
examples_zc/zcount et al. All hardware and MACs are as-was prior to the
move.
Any suggestions for diagnostics or remedy would be warmly received.
Regards,
A.
