The following two leaf's in the optical might be missing after upgrade to 22.3 Software Versions.

lane_laser_output_power_dbm

lane_laser_receiver_power_dbm

However, these leafs were present in prior versions of 22.3 SW Version.

This issue might be seen if the following conditions are met:

• On all Junos EVO platforms.
• When Openconfig Telemetry is configured
• When the junos/system/linecard/optics leaf was subscribed.

Missing leaf's while subscribing to the interface parameters subscription for optical parameters.

This is fixed in the later versions of 22.3 and can be reported after subscribing to the interface parameters.
