Command Reference Guide
ip flow cache timeout
Use the ip flow cache timeout command to configure the integrated traffic monitoring (ITM) cache for
entry expiration. The no form of this command resets the expiration time to the default setting. Variations
of this command include:
ip flow cache timeout active <minutes>
ip flow cache timeout inactive <seconds>
Syntax Description
active <minutes>
inactive <seconds>
Default Values
By default, active flows are set to expire in 30 minutes, and inactive flows are set to expire in 15 seconds.
Command History
Release 16.1
Functional Notes
Traffic flow entry expiration can occur in one of three ways: (1) the configured expiration time has passed;
(2) the Transmission Control Protocol (TCP) connection between the cache and the flow collector has
expired due to FINISH/RESET signaling; or (3) critical configuration changes have been made (for
example, changing the sampling rate). The default mode of expiration is based on a configured number of
minutes for the traffic flow entry to be stored in the cache.
Usage Examples
The following example configures an expiration time of 15 minutes for active traffic flow entries:
(config)#ip flow cache timeout active 15
60000CRG0-35E
Specifies the amount of time a single traffic flow that continues to have
packets detected at the observation point is stored before exportation.
Range is 1 to 60 minutes.
Specifies the amount of time that idle traffic flows (which no longer have
packets detected at the observation point) are stored before exportation.
Range is 10 to 600 seconds.
