Re: EEM Applet - Restarts Router

Hello,

Yes, the correct increment is: "action 7.0 increment i", then the applet is
working fine.

Stiil, there is not an endless loop, because the $_cli_result has a finite
number
of lines. Or am I missing something? I think that the crash is because I
increment a variable, "counter", who does not exists.

Regards,
Rares
