Issue/Introduction

Spectrum Network Configuration Manager (NCM) requires the device be modeled in the Spectrum database with a read/write community string. However, I do not want regular users to have read/write access to the devices associated with the model. How to configure Spectrum to allow the use of NCM while preventing regular users from having read/write access to the devices associated with the models.

Environment

Release: Any
Component:

Resolution

First you will need to use Spectrum model security to configure user access to the models. Configure the model security so the "regular" users do not have read/write access to the models. Reference the "Model Security in OneClick" section of the Spectrum documentation.

Second, model the device with a read only community string

Third, populate the CommunityNameForSNMPSets attribute 0x11a7f with a read/write community string. This can be done by selecting the model and updating the attribute from the Attributes tab or using the Attribute Editor.

By populating the CommunityNameForSNMPSets attribute 0x11a7f with a read/write community string, users that have read/write access to the model through Spectrum model security string will cause Spectrum to use the community string from the CommunityNameForSNMPSets attribute 0x11a7f when they need to write to the device.
