Spectrum modeling infrastructure guide talks about populating the serial number value if the Mib contains the serial number in a custom object. This Tec Doc is an enhancement to this information and talks about how you can perform the same if the data type of the custom Mib object differs from Serial Number attribute type.
In normal scenario DeviceSerialAttr holds the custom serial number mib object id to populate the serial number in Spectrum Oneclick. For this to work the custom mib object attribute data type should be a text string as serial number attribute type is text string. This will not work if the data type of custom mib object attribute is different from text string - i.e. if it is a list data type.
Follow this solution to make this work. This solution assumes that the custom mib object is already mapped to a custom attribute from Mib tools.
Now observe that the serial number attribute holds the correct value populated by the custom Mib object. As a whole you are just creating a new attribute on custom model type whose data type is text string which is same as serial number data type .
