NRM-Attributes

[Lothar Mueller]

Hi all,

as I was unable finding any docs about the NRM_xxx Attributes of models, hopefully the community is able to

put some light one this.

As we had any issue with wrong SW-Versions reported by JasperSoft I digged into the problem and found that

an Device-Attribute NRM_RunningFirmware wasn't up-to-date (reconfigure model updated it).

With that discovered I wasn't able to get behind the concept of NRM-Attributes and how they are created.

Is there anybody in this community able to explain the concept behind NRM-Attributes?

And, second question: How can I update NRM-Attributes for more than one model (CLI, ...)?

Thanks for helping.

Lothar,

The NRM attributes (NRM standing for Normalized) are used to populate attributes like firmware, CPU, memory where there is no standard mib for these attributes. However, that information could be located within a standard mib attribute like the sysDescr or a vendor private mib. They give the developer of the model type the ability to specify which mibs to look at to get the information to populate the values for firmware, CPU and memory or the user to customize where to get that information.

This was done mainly so users can use the same attributes for firmware, CPU and memory and not have to worry about this is the firmware attribute for Cisco devices and this is the one for Juniper  devices and this is the one for XXX devices etc, etc, etc.

All of the NRM attributes work in the basic same way. The following are some knowledge article and document references that should help to understand.

Spectrum uses the same process to populate the serial number but the attributes do not start with "NRM".
