<div>Just out of curiosity and as I haven't seen an answer in
the thread yet - maybe</div>
<div>I overlooked something ...</div>
<div>Is this to control some link-triggered redundancy setup
with switches?</div>

Revisiting my own question/thread.<br>
Yes. Very close to what Klaus wondered - it's a device over which I
have no control and from that device perspective it's simply - link
is up then I'll "serve" it.<br>
I've been thinking lowest possible layer shall be the safest way -
thus asked about controlling eth link that way: down/up by means of
electric power, ideally.<br>
As opposed to ha-cluster calling some middle men such as network
managers.<br>
I read some eth nics/drivers can power down a port.<br>
Is there an agent & a way to do that?<br>
<br>

Kind of similar - tcp/ip and those layers configs are <br>
delivered by DHCP.<br>
I'd think it would have to be a clone resource with one <br>
master without any constraints where cluster freely decides
<br>
where to put master(link up) on - which is when link gets <br>
dhcp-served.<br>
But I wonder if that would mean writing up a new resource -
<br>
I don't think there is anything like that included in <br>
ready-made pcs/ocf packages.<br>
<br>
many thanks, L<br>
