I don't understand waht happend. My BMC on R310 don't responds ping. As
BMC IP: 172.30.0.150
SO (Debian) IP: 172.30.0.151
When I ping 172.30.0.151 all works perfectly.
IPMI over LAN is activated (I checked it in the BIOS config utility and
in the OSMA web GUI).
Something that came to my attention is that in the OMSA LAN
configuration I get the following message (Spanish):
"Precaución: El tráfico de administración del acceso remoto no funciona
correctamente cuando la LAN en la placa base (LOM) está integrada a
cualquier tarjeta complementaria adaptadora de red."
In english is something like that:
"Warning: The administrative traffic of remote access don't work
correctly when the LAN in the motherboard (LOM) is integrated to any
complementary network adapter."
I can't figured out what this message exactly means. When you don't have
iDRAC (like in my R310) the administrative traffic must be shared with
normal traffic (OS traffic), so, why I get this warning message?.
Thanks and regards.
