We have a PA-5020 and configured a few AGG interfaces with subinterface; recently, we installed a SolarWinds NTA to get NetFlow statistics, but I am not able to get anything from this device.
I have created a profile and applied to the subinterface through which the Internet traffic goes, but it does not send any information to the NetFlow collector.
Also, is there a way we can monitor the AGG and subinterfaces using SNMP?
We do manage the device with SNMP through the management interface and I can see the physical interfaces, but not the AGG and subinterfaces.
Thank you very much.
The SNMP counter for logical interface is reporting incorrect values,
This is what I got back from TAC,
For hardware interfaces (ethernet1/21 and ethernet1/22), we only populate ""Physical port counters read from MAC" in the SMNP MIB.
These are MAC counters at the physical interface level.
For logical interfaces (AE1), we only populate "Hardware interface counters read from CPU" in the SNMP MIB.
As we do not actually have a physical interface for AE1, the MAC counters at physical level are not applicable here. We will only look for the Hardware CPU counters here.
Because most of the packets never reach the CPU as they are offloaded, we don't see a significant increment in the Hardware CPU counters.
As the counters on the hardware interfaces and the logical interfaces use different types of counters, it is not appropriate to compare the values on HW interfaces and Logical interfaces.
