The IPS40 is showing missed packets yet the Inspection Load remains at 0.
Two questions.
1. What would cause Missed Packets and is there a "best" method to troubleshot the situation?
2. Why does the Inspection Load remain at 0?
vs0 is currently assigned to PortChannel0/0 (Backplane interface)
Thanks,
Kevin

Theres a known bug in 7.1.6 that causes this.
Rebooting the sensor will fix it for a period of time. Fix is scheduled in 7.1.7

Hello Kevin,
Importan to let you know that for missed packets the IPS count packets being dropped byL2errors and oversupscription.
Based on the load being on 0 I would say it would make sense to think about L2 errors, is there a way you could doble check the layer 2 connectivity between them.

The IPS and Firewall are connected through PortChannel0/0. Not sure how you can check L2 connectivity on a backplane connection. Any ideas?

Hello Kevin,
What version are you running
Also share the following:
show stat virt
show int
Also over the show tech look the following :
exec: cat /proc/net/cisco/cids-shared.info
And let me know the free buffer percentage you see there

Hello Kevin,
On the show tech I do not see the missed packet percentage on 50 % or any other value than 0
Can you double check that please

jcarvaja,
Having just witnessed another indication form the Sensor Health gadget that packets were being missed, I again ran the commands you suggested with a result of 0 missed packets in the output. Is it possible the Sensor Health gadget is reporting false indications?
Thanks,
Kevin
