The Device Connectivity Service (DCS) is responsible for establishing and maintaining the connection to the SRX Series Firewall. The service handles requests for any interactions with the device, such as deploying configurations. Follow the steps in this topic to troubleshoot DCS.

Problem

The DCS is not operational. This issue may affect the capability of Juniper Security Director to communicate with managed firewalls and execute specific tasks such as remote management, monitoring, or integrating with other network services.

To check the status of services running on the VM, navigate to Administration > System Management > System.

Solution

To resolve this issue, check the configuration settings, ensure that the service is enabled, and troubleshoot any underlying problems that might be causing the service to be inactive.

Follow the steps below to verify the status of the DCS service and its configuration. You can share this information with the Juniper Networks support team to troubleshoot any issues.
