Andy,
I'm using ipmitool version 1.8.11.
Corey,
ipmitool didn't recognize the retry' responses. Typically this is what
happens:
ipmitool -> BMC: What is IP?
ipmitool -> BMC: What is IP? (retry)
ipmitool -> BMC: What is IP? (retry)
BMC -> ipmitool: IP is 192.168.1.1
ipmitool -> BMC: What is MAC?
BMC -> ipmitool: IP is 192.168.1.1 (retry)
ipmitool -> BMC: What is IP Source?
BMC -> ipmitool: IP is 192.168.1.1 (retry)
BMC -> ipmitool: MAC is 00:40:D9:02:97:16
BMC -> ipmitool: IP Source is 2
Tool parses the output as:
IP - 192.168.1.1
MAC - 192.168.1.1.0.0
IP Src - 192
I shall get the wireshark captures if required.
Thanks
Yugender
