CLI syntax to change i-rule order

Hi;

 

Let's say I had a virtual server called Vserver and I had to irules bound to it. i-rule1 and i-rule2

 

In the Web based console "GUI", I can control the order by going to Local traffic >> virtual servers >> virtual server list, then I choose the virtual server Vserver and go to resources, irules and I can change the order of the two irules.

 

So I can put i-rule1 on top and i-rule2 below it.

 

My question now is: how can I do that in the CLI?

 

Kindly

Wasfi

    Hi Grandiser,

    You can use

     

    tmsh edit ltm rule 'name_of_the_iRule'

     

     

    2nd method

    Create a new irule with new name using create command with new rule order sequence 

    tmsh create ltm rule NEW-IRULE irule1 irlue 2

    then use modify statement in the Virtual server to switch the iRule to new iRule

    tmsh modify /ltm virtual rules { NEW-IRULE }

    Please note  this will removes all the applied irules and only adds the new irule inside the curly braces.

    When using tmsh, you can only create iRules using the editor, which starts when you use the create or edit commands. You cannot create an iRule directly on the command line. The vim editor applies the autoindent and smartindent options. You can toggle on/off paste mode using the F12 key.

    Hope this helps
