Hi Bill,

I guess you are right, but what happens if I DO want to stay in
active/backup for a while and switch to round robin later?
Is it a bug?

Thanks,
       Eduard.

Hi, Eduard

Please put the cables back after change the mode to round robin,
and then ping the remote PC

The scenario is:
1 Create a bond with 3 interfaces (connect them to switch).
2 Change bond's mode to active/backup.
3 Physicly remove two cables form interfaces ( not the active interface ).
4 Change the mode to round robin.
5 Put the cables back
6 Try to ping some other computer.

Hi,

Now?only?one?interface?is?pinging?to?remote?computer.
Without?removing?the?cables?all?three?interface?will?ping?to?remote

I?did?some?debuging,in?the?code,?and?I?see?that?in?round?robin?all?the
interface?is?in?active?(and?all?of?them?transmiting?periodically).
After?removing?and?puting?back?the?cables(in?active/backup?mode).?the
interfaces?change?their?status?to?backup.
After?this?only?one?interface?is?transmiting?(?the?one?which?was?the?active).

Thanks?in?advance,
