[Ipmitool-devel] Bridged sensor read doesn't work in 1.8.13, works ok in 1.8.11

[Siegel, Jeffrey]

I have a micro-TCA chassis with an MCH made by NAT Gmbh. I use ipmitool over LAN to talk to the MCH, and other cards in the chassis.

This command allows me to read the sensor data from the card in slot AMC7:
$ ./ipmitool.exe -H 10.168.0.3 -P "" -T 0x82 -B 0 -t 0x7e -b 7 sensor

For ipmitool version 1.8.11, the output is:

Hello Jeffrey,

there were some changes related to bridging. You might want to follow
on those. I can't help you further than that.

Good luck and best regards,

Z et All,

I'm working with Jeff on trying to figure out what is going on with his
micro-TCA chassis.
Sorry I neglected to include ipmitool-devel on this.

FYI: My current thought is that SDR repository indicates that sensors
are on channel 0 instead of
of where they really reside, on channel 7. I'll let everyone on the
list know what we find out.

Thanks,
Jim
