Not able to discover Palo Alto firewall devices via schedules or quick discovery some times.Issue Not able to discover Palo Alto firewall devices via schedules or quick discovery some times. Credentials are validated successfullyDevice's are getting discovered intermittentlyReleaseAllCauseSNMP uses UDP, which does not create a virtual connection to the target host as TCP, and no reply may be given if a credential is not correct or authorized depending on the version used. A timeout can be seen in the discovery log when an invalid credential is used.Error ind discovery logs "SNMP probe timed out. Target is either unreachable or there are no valid credentials for it"Couple of reasons for a timeout are: The credential is not valid --- tested credentials(Validated successfully)The network or target server is too busy and does not return the OIDs within the timeout. ResolutionAdd the below probe parameter for SNMP-Classify probe, "request_interval" Add "request_interval" probe parameter and set the property to 1000ms. Default is 400ms.This will fix intermittent discovery issue of Palo Alto firewall devices.
