Start/Stop Capture

This button controls whether the Passive Capture device captures packets from the network. When started, it captures packets. When stopped, it does not capture packets. Capture cannot be started if it is disabled.

When you Stop Capture, the Reset all statistics before starting capture checkbox is displayed.

Note: If PCA master/slave machine failover is enabled, do not check the Reset all statistics before starting capture checkbox to clear statistics. Clearing or resetting statistics prevents failover from working correctly. If clearing statistics is needed, first stop failover in the Failover tab. Restarting the PCA correctly sets machine failover state with statistics cleared.

Enable/Disable Capture

This button controls the behavior of the main capture application when the service is started at boot time, from the command line, or from the Web Console. When enabled, the main capture application is allowed to start. When disabled, the main capture application is not allowed to start.

Enable/Disable Web Console Time Out

By default, the PCA Web Console is configured to time out sessions if no activity is detected in 30 minutes.

• To disable the console timeout, click Disable. If user authentication for the Web Console is disabled, a console timeout is not applicable.
• To enable a console timeout, click Enable. Enter a non-zero value for the number of minutes to set for the timeout. Then, click Set.

  Console tabs that auto-refresh, such as the Summary tab and the Console tab, do not reset the timeout. The console timeout can be enabled or disabled and you can configure the length of the console timeout.
