Integrated Traffic Monitoring Configuring ITM and Top Traffic Using the GUI

Setting Traffic Flow Entry Expiration

Traffic flow entries are the data collected about traffic flows. Entries are stored in the flow cache and are

termed either active or inactive. Active traffic flows refer to the maximum life of a single flow that

continues to have packets detected at the observation point; inactive traffic flows refer to idle flows which

no longer have packets detected at the observation point. When traffic flow entries expire, they are ready to

be exported to the flow collector. To set the expiration times for active and inactive traffic flows, follow

these steps:

1. Continuing with the cache tab, the expiration time for active flows in the appropriate box. The range of

storage time is 1 to 60 minutes, with a default expiration time of 30 minutes.

2. Enter the expiration time for inactive flows in the appropriate box. The range of storage time is 10 to

600 seconds, with a default expiration time of 15 seconds.

3. Select Apply to apply the settings.

Configuring Traffic Flow Export

Specifying a destination for traffic flow exportation allows the data collected to be sent to an external data

collector for analysis.

This feature can be used in conjunction with ITM Top Traffic. If only Top Traffic is being

used, traffic flow export does not need to be configured. For Top Traffic configuration

steps, refer to Configuring Top Traffic Using the (GUI) on page 17.
