Do you know if Juniper MX(12.3) using Inline Jflow are able to advertise samplingPacketInterval and samplingPacketSpace fields ? We have inline flow instance configured on our equipments but i cannot spot these fields in pcaps. Configuring Flow Aggregation to Use IPFIX Flow Templates docs seems to indicate i should have any hope. http://www.juniper.net/techpubs/en_US/junos12.3/topics/task/configuration/s ervices-ipfix-flow-template-flow-aggregation-configuring.html If anyone have informations or clues, thanks by advance.
