Thanks a lot for that detailed explanation.
It wasn't clear to me that the blades were using a special VLAN for
communication with the AMM (which is indeed what we're using)
I'll keep the non ipmi details off list.

On the IBM Blade platform, you will probably never see out of band
access via IPMI to the BMCs. The BMCs for most operations communicate
via the Bladecenter internal RS485 bus to the Management Module. All
external access is arbitrated by that.
The BMCs do talk via LAN, however their authentication mechanism is
greatly simplified (probably to the point of non-compliance and hence
even if you get ipmitool on that VLAN, it probably won't work), and
talks over a special vlan tagged by the on-board NIC (the management
module calls it the 'sol vlan' or something like that, default 4095),
and all ethernet switch modules are configured to not let that VLAN out
on external ports. It may be possible to get that on external ports
depending on which switch module you buy, but that's really not going to
end up a productive way to go.
