How to use inputlookup file.csv to filter out results from a search

[sbattista09]

here is my current search that im running
index=test outbound "/22" cisco_dsthost!=10.0.0.1| RENAME cisco_dsthost AS Scr_host | RENAME cisco_srchost AS Dst_host| stats count by Scr_host, Dst_host

I want to add a inputlookup file.csv that has IPs inside of it that i want to exclude from that search. I want it to do something like -
index=test outbound "/22" cisco_dsthost!=10.0.0.1 NOT [|inputlookup file.csv] | RENAME cisco_dsthost AS Scr_host | RENAME cisco_srchost AS Dst_host| stats count by Scr_host, Dst_host

i have already uploaded the CSV file to splunk lookups directory and tested that splunk can pull it in. I just cant get the results to filter correctly.

It works exactly like the search you already wrote, as long as the CSV file contains one single field that's called whatever field you want to filter by. So if for instance the field you want to filter by is cisco_dsthost, your CSV needs to look something like this:

cisco_dsthost
1.1.1.1
1.1.1.2
...
