flow timeout
Command History Release
6.1(2)

Usage Guidelines The active timeout is the amount of time to wait before sending flow information about an active session.
The flow is not removed from the cache after this timeout; however, the packet count, byte count, and
timestamps are reset.
The aggressive timeout only affects hardware caches and is used when flows are being received faster
than expected. If flows are being received faster than the threshold, they are aged out of the cache.
The fast timeout specifies when an inactive flow should be aged out.
The inactive timeout is used for Transmission Control Protocol (TCP) sessions that receive no more data
from the sender (FIN) followed by an acknowledgment field is significant (ACK) or a reset (RST) packet
being received. The inactive timeout indicates the session is over and the flow can be aged out.
Note Only the flow timeout seconds command is supported for F2 Series modules. All of the other NetFlow
timeout commands are supported for M Series modules only.
This command does not require a license.
Examples This example shows how to specify the active or long timeout value in seconds for the F1 and M1 Series
modules:
switch(config)# flow timeout active 45
switch(config)#
This example shows how to specify the percentage of the NetFlow table content:
switch(config)# flow timeout aggressive threshold 45
switch(config)#
This example shows how to specify the fast aging timeout in seconds:
switch(config)# flow timeout fast 30 threshold 20
switch(config)#
This example shows how to specify the inactive or normal timeout in seconds:
switch(config)# flow timeout inactive 45
switch(config)#
This example shows how to specify the flush cache timeout in seconds for F2 Series module:
