Duplicate IP address 192.199.199.x - IBM BladeCenter
RETAIN tip: H197407
A network trace of a blade interface may reveal duplicate internal management network Internet Protocol (IP) addresses.
The system may be any of the following IBM servers:
The system is configured with one or more of the following IBM Options:
This tip is not software specific.
The Advanced Management Module (AMM) uses IP addresses 126.96.36.199 and 188.8.131.52 to communicate with the blades' service processors.
Blade service processors use IP address range 184.108.40.206 - 220.127.116.11. This IP address range cannot be altered with AMM firmware 3.54D (Build ID BPET54D) or later.
Performing a network trace of a blade interface mirrored to another chassis may report that duplicate addresses are in use.
Duplicate addresses may also be reported if a network trace of a blade interface is performed in an environment where switches are stacked between chassis.
Seeing duplicate addresses when performing such mirrored traces is not indicative of an issue.
