The following two sensors for QFX-5110 are published on Juniper’s website but are not working.

https://apps.juniper.net/ydm-explorer/select-platform?software=Junos%20OS&release=23.4R2-S3&moduleId=All&datamodel=OpenConfig&filter=Supported&platform=31705110&tagId=1336857&tagName=config

From Ubuntu server to QFX5110, below command just hangs:

root@ubuntu:~# gnmic -a 10.85.153.149 -u user -p Password subscribe --path /components/component/optical-channel/state --insecure --port 50051

As a test on other platforms, the command is successful and returns data:

root@ubuntu:~# gnmic -a 10.85.173.250 -u user -p Password subscribe --path /components/component/optical-channel/state --insecure --port 50051

    }
  ],

DEV engineer confirmed that they found the feature is excluded on the QFX platform on 23.4R2-S3. Fix has been committed to Junos:25.4R1

Telemetry sensor data is not returned for /components/component/optical-channel/state and /components/component/optical-channel/config

Fix has been committed to Junos:25.4R1
