ISSUE: Spectrum not modeling interfaces although there is a configuration for the interfaces in the interfaces mib
ROOT CAUSE: ifAlias may not be unique across all interfaces
RESOLUTION: Reconfigure the device so that ifAlias is unique across all interfaces.
WORK AROUND: Set the Use_If_Alias attribute id 0x11f80 on the device model to "No". This can be done using the Attributes tab, the Attribute Editor or the Command Line Interface. After setting the Use_If_Alias attribute id 0x11f80 on the device model to "No", the device model will have to be reconfigured by right mouse clicking on the device model and selecting Reconfiguration -> Reconfigure Model from the menu.
