Hi Bob,

You can manually add the datagroup entries via the GUI under Local >> Traffic >> iRules >> Datagroup tab. Or you could reference an external file. The format for an external file is in 10.0+ is: 


class namevalue {
  "name1" := "value",
  "name2" := "value",
}

Another option would be to use the bigip.conf format in a separate file and then merge the file into the bigip.conf using 'b merge file'.

The format for an inbuilt datagroup in the bigip.conf is: 


class namevalue {
   {
      "name1" { "value" }
      "name2" { "value" }
   }
}

Lastly, you could use iControl to upload an external datagroup file and then use a Codeshare example from Joe to reload it:
