ip flow-cache active-timeout
Specifies the number of minutes that an active flow remains in the cache before expiring.
Syntax: ip flow-cache active-timeout minutes
no ip flow-cache active-timeout
minutes
Specifies the number of minutes an active flow remains in the cache before expiring.
Description: Netflow packets are only created after a flow either expires or is timed out. It is desirable to put a maximum time limit on how long a flow may be active without expiring. The flow cache active timeout parameter allows for the setting of a maximum amount of time a flow can remain active without expiring.
Use the ip flow-cache active-timeout command to set the number of minutes an active flow remains in the cache before expiring.
Use the no ip flow-cache active-timeout in configuration mode to globally specify the number of minutes an active flow remains in the cache before expiring. Use the no ip flow-cache active-timeout command in module configuration mode to delete the timeout configuration for that module. This command has the affect of setting the module timeout to the globally configured value.
Factory Default: 30 minutes
Command Mode: Configuration for global affect and Module configuration for per module affect.
Example 1: The following example sets the global value for the flow cache active timeout to 10 minutes and the value on module 2/1 to 5 minutes
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#ip flow-cache active-timeout 10
router(config)#module 1/2
router(config-module)#ip flow-cache active-timeout 5
router(config-module)#exit
router(config)#
