Znyx Networks bh5700 - Manual (Page 309)

<port-list> A list of ports in the same forms supported by
zconfig, e.g. zre1,zre2 or zre10..14
<program> Path to an executable program or script to be run when
the event occurs. Note: An absolute path to <program> is
required. The program will be called with the following
parameters:
For Link Changes:
<program> <ppa> <port> {external(0)|internal(1)} {off(0)|on(1)}
For Hot-swap Events:
<program> <ppa> {extraction(1)|insertion(2)}
NOTE: The <ppa> parameter is undefined and should be ignored.
EXAMPLES
In the following example, zlmd monitors ports 1 through 4 and runs a script called
prt_change upon a link change event.
zlmd zre1..4=/usr/sbin/prt_change
Suppose port 2 were UP and you disconnected the cable, zlmd would call prt_change with
the following parameters:
/usr/sbin/prt_change 0 2 0 1
where 0 is the ppa, 2 is the port, 0 is an external fault, 1 is ON.
