I'm trying thru CLI to enable for blocking attack signatures released after a particular date of July 13 2020. For that I'm trying to load the signature Ids in a file thru the command below, I got the date converted to microseconds using epochconverter.com/ before putting in the API call. When I ran the command from CLI I see old signatures are also getting loaded. If I check this on the Attack signatures GUI using filter ( update date after July 13 ) it shows 2 signatures only. Am I using the API incorrectly ?
# curl -sku admin:admin https://10.1.1.4/mgmt/tm/asm/policies/POLICY_ID/signatures?/$filter=lastUpdateMicros%20gt%1594598400000 | jq '.' | grep -- 'lastUpdateMicros\|signatureId' | grep signatureId | tee signature_list.txt
