Additional Information

Currently is not possible to change List/Table attributes of "Internet Address" type (i.e 0x12d84 - RedundancyPreferredAddress) :

 

In the example below, we try to change the ip address value in the Instance ID "1" of the attribute to "000.000.000.000", and you will get the following error:

In the Oneclick Tomcat log file, we can see the following:

java.lang.Exception: DefaultSpectrumAttributeConfig.makeCsCValue: Object 000.000.000.000 of class java.lang.String could not be converted for attrID 0x12d84 of type CSC_INTERNET_ADDRESS

        at com.aprisma.spectrum.app.topo.web.repository.ModelRepository.writeAttrTable(ModelRepository.java:6708)

 

Engineering has debugged the code and identified the root cause of the issue, and it requires a code change to get this fixed. Actually we did not handle the INTERNET ADDRESS type for this attribute value and hence its failing when we pass internet address as a new value.
 
This is targeted to be fixed post Spectrum 22.2.7 version.

Currently, you can use CLI as a workaround:
