Randall,
Yes, that is how IPMI LAN works, and you probably do have something
wrong in the IPMI LAN configuration on the server.
There are a number of IPMI LAN parameters that may need to be set up:
BMC IP, gateway, MAC, channel, user, SOL, PEF, etc.
Note that you might have configured the baseboard NIC (usually IPMI
channel 1) when you meant to configure the dedicated BMC NIC (usually
IPMI channel 3).
You can view all of the various parameters via several ipmitool
commands, or I like the way that ipmiutil.sf.net shows all of the
LAN-related parameters with one command ("ipmiutil lan", or "ipmiutil
lan -L 3" for channel 3).

Subject: [Ipmitool-devel] IPMI BMC with dedicated management
port(RJ-45).... connecting over LAN??
Greetings,
This is my first post to this mailing list and I'm hoping that someone
can help me better understand how to connect to IPMI through a dedicated
management port. I've read pretty much everything I can get my hands on
and I'm still a bit in the dark.
I have 2 servers that will eventually be members of a cluster, and my
initial plan was to use IPMI over LAN for cluster fencing. The servers
have a 'management port' (RJ-45) that I connected to a switch via
standard CAT-5e. I used IPMItool to assign IP addresses/netmask, with
the intention of having a small network specifically for IPMI traffic.
The problem is that I can't connect to any remote machines using the LAN
interface. Using the -vvv option I can see the initial ping-discovery
packet, and it is being sent to the correct address, but nothing ever
comes back. I can only assume that either there is no communication, or
I've setup something wrong.
The strange thing is that the management port does not show up as an
interface when I do an ifconfig -a. However, I'm not sure if it is
supposed to. This isn't a normal NIC, it is supposed to be hooked
directly into the BMC and useable even if the server is powered down.
That is why I wanted to use it for fencing.
Has anyone seen this type of setup before? From what I've read the LAN
interface of IPMI seems to make reference to interfaces that the OS is
aware of. Is SOL what I need in order to use the management interface?
Any help would be appreciated. I can confirm that IPMI is working
locally, it's just getting to a remote machine over the network that is
not working.
