Issue/Introduction

This article addresses the following questions:

• Can Smarts NCM discover the same device into two different networks?
• Is it possible to get the same device to display in two different networks managed by Smarts NCM?

Environment

NCM - 10.1.X

Resolution

Smarts NCM cannot discover the same device into two networks, as the discovery operation can only discover a device once per device server. Once the device is discovered into a network, it becomes the primary network. Smarts NCM cannot discover the same device into a second or secondary network. However, you can have the same device display and be managed in a secondary network, but it must be managed manually. With this type of manual management, the same device could be added/displayed in multiple secondary networks. To manually add a device that has already been discovered in a primary network by Smarts NCM for management in a secondary network, do the following:

1. Go to Tools > System Administration.
2. Browse the tree to System Administration > Networks > [Target Secondary Network] > Devices.
3. Click the Manage button at bottom right. Apply a filter against Managed Devices. Specify additional characteristics about the device if you have many thousands of devices (IP addresses and Network Name has been removed from screen captures below):
 

 

 

 

4. Locate the desired device(s) and move them from the left list to the right list.
 

 

 

 

5. Click OK (or apply or manage) to Manage those devices into the secondary network.
