How to prevent the DUPLICATE MAC WITH DIFFERENT IP DETECTED alarm in SPECTRUM on a per model basis

Problem Environment:
Spectrum 09.01.02.00 or greater
DUPLICATE MAC WITH DIFFERENT IP DETECTED
0x11ce2
0x10519
0x10911
In some cases, users may have a need to have two or more models that have the same mac address. The default functionality in Spectrum is to assert a DUPLICATE MAC WITH DIFFERENT IP DETECTED alarm (Event ID 0x10911 Probable Cause ID 0x10519). This is a user clearable alarm. However, after the user clears the alarm, it will be re-asserted after a while.
To disable the alarm from being re-asserted after clearing, the user can set the  attribute NeedDuplicateMACDiffIP (0x11ce2) to "No" on ALL the models with the duplicate mac address. This can be done using one of the following:


1. The Command Line Interface


2. The Attribute Editor


3. The Attribute tab in the Component Detail panel (Spectrum 09.00.00.00 only)
