Accessing Data Frame unique layer ID's using Arcpy

Question

In ArcMap 10.3 the option to assign unique layer ID's was enabled. When enabled this allows map authors to set the numeric ID's accordingly.

Can this data frame property be read in Arcpy to determine if an MXD is using this setting?

Can arcpy access the layer ID thru the layer object?

Thanks for any info

Ronnie

Hi,

Has anyone found solution for this? I am working on automated map service publishing scripts and i would like to run checks on MXD to enforce the option being switched on by users before publishing.

Thank you Joshua! I was hoping to be able to access the unique IDs assigned to layers in the MXD when reading the MXD using Arcpy. It appears this property is missing from the Arcpy.mapping module and will likely submit an idea for this one.
