Learn about the different questions asked when configuring DDI.


Listed are the common questions encountered when configuring DDI:

Deep Discovery logs off after five (5) seconds of inactivity.

No, you cannot register Deep Discovery to more than one TMCM server.

Yes, changing the DDI IP address through the Pre-configuration console or the product console will cause temporary disconnection (30 seconds).

During this time, the Management Communication Protocol (MCP) agent will be disconnected from TMCM. The MCP agent logs off from TMCM and then logs on to provide TMCM with the updated information.

You may have entered the wrong password three times that is why you were locked out. DDI will lock you out for 30 seconds if you entered an incorrect password three times. You can try logging in again after 30 seconds.

If you use DDI only to monitor the network, then you do not need to configure the firewall settings. However, if DDI connects to the Internet for updates or to TMSP, then you need to configure the firewall to allow Ports 80, 22, or 443 traffic from DDI.

Make sure that:

  • The TMSP logon details are correct.
  • The firewall settings are configured to allow port 22 or 443 traffic.
  • The proxy settings are correct.

If you encounter issues, contact Trend Micro Technical Support.

Yes, you must reconfigure the Syslog server settings after a fresh installation of DDI if you will import the configuration file from TDA 2.6.

You need to add DDI to your network security product’s whitelist, as this could be causeD by your network’s security policy.

Restart the appliance and verify that it obtains an IP address. Connect an ethernet cable from the management port to a known stable ethernet connection and then restart the appliance.

No. Changing the DDI's hostname will not interrupt the network connection. It will just synchronize the related configuration files.
