* RAN and Network Slice based Flow Sampling is not applicable as the PFCP packets does not contain any RAN or network slice parameters.
** If RAN and Network Slice enrichment is not done, gtp-u packets will trigger RAN PULL to get RAN information from CPN. During this interval for ~3sec gtp-u packets will go through any matching configured rules, if no match they will get dropped or sent to the collector.
Post this (within ~3sec), RAN or network-slice flow Sampling will work if RAN enrichment succeeds.
Else, gtp-u pkts will take any matching rules or they will get dropped or sent to collector.
