Release Information

Statement modified in Junos OS Release 9.3. The expression option added in Junos OS Release 11.4.

Starting in Junos OS Release 18.3R1, when an SRX Series Firewall is configured with unified policies, you can configure multiple IDP policies and set one of those policies as the default IDP policy. If multiple IDP policies are configured for a session and when policy conflict occurs, the device applies the default IDP policy for that session and thus resolves any policy conflicts.


If you have configured two or more IDP policies in a unified security policy, then you must configure the default IDP policy.
