Sensor not displayed in the resource tree

After adding the Sensor and establishing trust, if the Sensor is not displayed in the resource tree, perform the following steps for troubleshooting:

Capture traffic using Wireshark in the Manager.
Verify if the Manager is receiving UDP response packets from the Sensor.
Configure the firewall to allow UDP traffic if response packets are not coming.
Verify if the Manager system has multiple NIC cards. If yes:
- For Windows-based Manager, open <Manager_Install_Dir>\bin\tms.bat.
  Note
  The default installation path for Windows-based Manager is %programfiles%\Trellix\IPS Manager\App.
- For Linux-based Manager (MLOS), open open tms.sh by executing the command edit tms.sh. For Linux-based Manager (Trellix OS) , contact Trellix support.
Later, modify the following line to assign the relevant IP address that is also used in the Sensor configuration: Set JAVA_OPTS=%JAVA_OPTS% -Dlumos.fixedManagerSNMPIPaddress=""restart Manager
You can enable detailed debugging messages by modifying the following file:
- For Windows-based Manager, <Manager_Install_Dir>\config\log4j2.xml file
- For Linux-based Manager, log4j2.xml file. To open this file, execute edit log4j2.xml
Find out and modify the following lines in the log4j2.xml file:
- ```
<Logger name="iv.core.DiscoveryService" additivity="false" level="debug">
            <appender-ref ref="DEVICE_CONFIG_LOG"/>
        </Logger>
```
- ```
<Logger name="iv.core.SensorConfiguration" additivity="false" level="debug">
            <appender-ref ref="DEVICE_CONFIG_LOG"/>
        </Logger>
```
The modified logs will be available in <Manager_Install_Dir>\logs\device_config.log file.
