Hi all,
I have been playing with OpenOspf lately, and I came to a place, when I nee=
ded to ensure that an ethernet interface should always go into DOWN state w=
hen it loses its link (physically, for example the switch becames turned of=
f). I have tried to hire the devd daemon to do the job with such small defi=
nitions:
notify 100 {
match "system" "IFNET";
match "type" "LINK_DOWN";
media-type "ethernet";
action "/sbin/ifconfig $subsystem down";
};
=20
notify 200 {
match "system" "IFNET";
match "type" "LINK_UP";
media-type "ethernet";
action "/sbin/ifconfig $subsystem up";
};
And what is happening? Well, basically, when the interface detects that eth=
cable has been detached, devd triggers and makes it DOWN, which is ok. But=
, when the card got the cable attached once again (and interface detects th=
e media type and gets ACTIVE state) devd never triggers the second rule, wh=
ich should get the interface UP again.=20
I have tried that with replacing action statements with ones with proper lo=
gging actions, and when interface is UP devd gets the proper state changes =
information.=20
Now the question is: why devd doesent receive any information from interfac=
es in DOWN state? Is that proper behaviour, or a bug? Thanks for any reply,=
and for your attention.
P.S. I am resending this message to freebsd-stable list, as I am not sure i=
f freebsd-questions was a proper choice.
