When running the CLI command 'show attributes' the returned output does not correctly show the model_handle attribute value for the model in question.
./show attributes attr=0x129fa mh=0x1220e8
Id Name Iid Value
0x129fa Model_Handle 0x0
In the above example instead of seeing the model handle for the model, a null 0x0 is returned instead. This can cause
problems for administrators who have automation scripts in place and require the value to be present in the output
It was found that the problem is caused by a recent change in Spectrum 10.4.1 on the handling of Keyed Attributes. The introduced change was
to pre-loaded the keyed attributes into Memory during SpectroSERVER startup. This however appears to cause an issue with the model_handle
attribute when being retrieved via the cli.
Release : 10.4.1, 104.2 (NetOps 20.2)
Component : Spectrum Core / SpectroSERVER
The caching of the keyed attributes can be disabled by adding the setting without quotes cache_keyed_attrs=false to the .vnmrc and
restarting the SpectroSERVER
When keyed attribute caching is disabled a log message will be printed in the VNM.OUT log at startup. This can be used to
verify the caching was successfully disabled.
