irule saved in memory but not in the actual bigip.conf

Hello,

 

 

I have run on a issue which is a big strange i'm running version

 

 

10.0.1 build 378.0 HF3

 

 

I create the irule issuing the command on the cli :

 

 

b rule my_irule '{}'

 

 

I can see the rule being created in memory but even after a b save all

 

 

or a config sync the irule is not saved in to the config file

 

 

this is very strange as I have another more recent version where this is working

 

 

 

Any clues ?

 

 

 

 

regards,

 

J
