WAAS Prepositioning

Unanswered Question

Hello, I have recently deployed an 11 site WAAS solution with 512s at all the branches and a 612s at two "central" locations. I am running WAFS and have enabled prepositioning to push out user files to each location.

As I pushed the files, the "preposition status" indicated that the transfer had terminated with the message "Preposition size limit was exceeded."

Is there any way to see the presence of the prepositioned files on the WAE appliance so I can determine which files were successfully transferred?

There is currently no way to display the objects that are prepositioned. However, you can enable the EnhanceDebugging feature in Expert Mode, which will generate more verbose logging for PP -- including the names of the files that are pre-positioned. You can find the parameters on the WAE running the WAFS Edge service:

Expert Mode > Rx > RxPrepositionConfig > Attributes > EnhancedDebugging

Zach, I am not familiar with the "expert mode" you mentioned. Is this a capability of WAAS 4.x ?

You can access Expert Mode on the device running the WAFS Edge service using the following URL:


The credentials are the same as those used to access the CLI or GUI.

Once in Expert Mode, navigate to:

Rx > RxPrepositionConfig

On the Attributes tab, change the EnhancedDebugging attribute to 'true'. Click 'Save' to save the changes.

The additional debug messages will be logged in:
