Syntax Error: "policy" unexpected argument

Trying to run the following commands so we can export the output:

 

tmsh save asm policy overwrite $profile xml-file $profileFileName

OR

 

tmsh save asm policy overwrite Nw-cms-ui xml-file Nw-cms-ui.xml

but keep getting the following error:

 

Syntax Error: "policy" unexpected argument

 

This is for a version 11.2 of BIG-IP

 

Thanks
