Parsing out VLANS from netflow collection

In I'm trying to figure out how to create a parsing rule that will allow me to drop anything from certain VLAN's prior to it ingesting. Trying to use the Collect and filter but can't seem to figure out how to exclude a VLAN without having to specifiy each network individually which would lead to a mess to look at having so many nested statements.

Hi @barnettml

Here is the sample for dropping logs.

When you write parsers, If there is no hit based on your parsing rule, XDR'll drop logs and will not write to target_dataset

[INGEST:vendor="PANW", product="XDR Agent", target_dataset="PANW_XDR_Agent_parsed", no_hit=drop]

filter _raw_log not contains "vlan12"
