set global-label FortiOS5.4.7

Hello all,

I would like to use Labels within FW policies to distinguish similar purpose of them.

Currently in 5.4.7 I cant find out how it turn on. If I put there the whole command -> set global-label "my label" it does nothing and it dissapear when I refresh the configuration. In CLI there is no such a command (using ? or tab). Regarding CLI reference it should be available.

What else should I allow to use the labels ?

Thanks in advance.
