Hi ,
if i want to execute a script when the pppoe fail, how??

:if($status != “connected”) do={

}
}

P.S.
Sorry for my bad english language..

Ok, thanks for all
but..
i run the code into a “on event” scheduler and not work..
i run in a script list and not work
other…
in a new terminal window,report an error in the line

:if($status!="connected")

and i correct with

:if ($status!="connected")

but not work :frowning:
what am I being wrong?
the complete code is :

/interface pppoe-client monitor pppoe1 once do={
:if ($status != "connected") do={
/system script run pppoe_fail
}
}

pppoe1 is a pppoe-client interface and run correctly
the script (pppoe_fail) is an example and execute 3 beep simply…
Thanks.
