Using Include's for bigip.conf to define classes

One of the Data Group types is external which can point to a file in either the /config or /var/class directories. Here's an example bigip.conf reference to an external string class

 

 

class image_types_ext extern {
   type string
   filename "/var/class/image_types.txt"
}

 

 

Configuration help is available in the GUI or you can type "bigpipe class help" for commmand line help.

 

 

Keep in mind that simply overwriting the contents of the file won't cause the BIG-IP code to reload it into it's running configuration. You will either have to reload the config with a "bigpipe load" command. A recent forum post also covered how to maintain external class lists with iControl.

thanks for the quick response, what format does the file need to be in? its not clear in b class help. is this acceptable:

 

 

 

class test extern {

 

filename /config/strings

 

type string

 

 

start file contents:

 

 

string test

 

string test1

 

string test2

 

string test3

 

 

end file contents

Here are the contents for my "/var/class/image_types/ext.txt" file

 

 

".bmp",

 

".gif",

 

".joe",

 

".jpg",

 

".tiff",

 

 

I believe it's the same format that is saved in the bigip.conf for internal classes so if you are unsure you can always create an internal class and look at it's format. If you don't have it formatted correctly you'll probably receive a load error.
