Cisco Cisco ASA for Nexus 1000V Series Switch

The template keyword indicates the template-specific configurations. The timeout-rate keyword 
specifies the time before templates are resent. The minutes argument specifies the time interval in 
minutes at which the templates are resent. The default value is 30 minutes.

To change the time interval for sending flow-update events to a collector, perform the following steps:

Configure NetFlow parameters for active connections.

Example:

ciscoasa(config)# flow-export active refresh-interval 30

The value argument specifies the time interval between flow-update events in minutes. Valid values are 
from 1 - 60 minutes. The default value is 1 minute.

If you have already configured the flow-export delay flow-create command, and you then configure the 
flow-export active refresh-interval command with an interval value that is not at least 5 seconds more 
than the delay value, the following warning message appears at the console:

WARNING: The current delay flow-create value configuration may cause flow-update events to 

appear before flow-creation events.

If you have already configured the flow-export active refresh-interval command, and you then 
configure the flow-export delay flow-create command with a delay value that is not at least 5 seconds 
less than the interval value, the following warning message appears at the console:

WARNING: The current delay flow-create value configuration may cause flow-update events to 

appear before flow-creation events.

To delay the sending of flow-create events, perform the following steps:

Delay the sending of a flow-create event by the specified number of seconds.
