* RAN ForwardList is Not Applicable - as the PFCP packets does not contain any RAN parameters.
** If RAN 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 configured matching rules, if no match they will get dropped or sent to collector.
Post this (within ~3sec), RAN filtering will work if RAN enrichment succeeds.
Else, gtp-u packets will take any matching rules or they will get dropped or sent to collector.
