You configure Symantec DLP to use an installed Endace card, but when you run a 'dagconfig -si' the Link connection is not stable, and goes up and down (switches back and forth between 1 and 0). In some cases, the link may be stable, but the packet capture component starts and stops intermittently and will not stay running.
One possible cause for this is a failed upgrade of the Endace drivers that DLP uses. To resolve this, you can remove the drivers and executables for Endace from the DLP install and replace them with the current Endace drivers.
Step 1: Verify the version of Endace drivers:
Step 2: Verify the location of the Endace driver files:
Step 3: Remove the DLP copy of the Endace drivers
