Hello all,
I have a query from our customer, which have implemented Cisco Stealthwatch v.6.9.0, which consists of Flow Collector 4200 as a hardware appliance and SMC as a virtual machine. So far, Flow Collector collects flows from 4 Cisco Nexus 7700 switches.
Customer is reporting that not all flow export is collected from the Nexus switches, because they were creating some sample traffic which was not present in SMC.
Can anyone tell me is there any sort of processing of flows on a Flow collector or SMC which could ignore certain flows, or maybe the problem is in the configuration of the Flow export on the switches.
If the latter is the case, which configuration of the flow export could cause this? Can it be the case that the switches are sending just samples of flows in order to reduce impact on the performance.
Thank you
