Hierarchy Level


Specify the timeout value in seconds for the application system cache (ASC) entries.

ASC saves the mapping between an application type and the corresponding destination IP address, destination port, protocol type, and service. By default, the ASC saves the mapping information for 3600 seconds.


On SRX Series Firewalls, when you change the timeout value for the application system cache entries using the command set services application-identification application-system-cache-timeout, the cache entries need to be cleared to avoid inconsistency in timeout values of existing entries.


ASC is not cleared when the IDP policy is loaded. Users need to manually clear or wait for the cache entries to expire.
