NetMRI discovery depends on a collection of under-the-hood features to ensure that polling and addition of devices in the network proceed smoothly and accurately. This chapter describes the three following critical tasks.

For how to execute a configured NIOS IPAM Sync, see 30804724 Synchronizing Between NetMRI and NIOS Appliances.

NetMRI supports synchronization of IPv6 subnet and address information between NetMRI and target NIOS systems, to automatically define networks in IPAM. Some subnetworks may not be reported to NIOS during IPAM Sync owing to their addressing being part of MPLS VPNs. |

Now you can run the configured synchronization between NetMRI and NIOS. For more information, see the next section, Synchronizing Between NetMRI and NIOS Appliances.
To edit a sync configuration, perform the following:
...
- Network sync: Newly-imported subnets are imported as “managed”.
- If the imported subnet conflicts with an existing subnet, it is not accepted. The imported subnet can go into a container as long as there is no conflict.
- If the subnet already exists, no changes are made.
- If the subnet is in IPAM but not in NetMRI, it is left in IPAM.
- IP address sync: New IP addresses are added and marked as “unmanaged”. If an IP address already exists, the field values is overwritten during the import.
- Before NetMRI 7.1.4 and NIOS 8.1, if the IP address exists in IPAM but it is not in the import file, it is left in IPAM.
- As of NetMRI 7.1.4 and NIOS 8.1, if the IP address exists in IPAM but it is not in the import file, its discovered data is cleared out. You can control the time that the IP address stays in the NetMRI database after it is no longer discovered under NetMRI. To do so, go to Setup -> General Settings -> Advanced Settings.
Viewing IPAM Sync Discovered Data in NetMRI and NIOS
In NIOS, you can view the data discovered by NetMRI and synchronized using IPAM Sync as follows:

NetMRI automatically supports an Infoblox utility, Cisco Discovery Service, that enables network administrators to provide Cisco-validated reporting and analysis. NetMRI operates as a Cisco Discovery Service-enabled system supporting discovery of network systems for analysis and management. You can use the CDS Integration Tool as part of a new NetMRI installation, or use the tool to extract further insight and value from an existing deployment. Cisco Gold Partner status is required for effective use of the software utility.
NetMRI supports CDS API version 2.0 and uses a NetMRI device or virtual machine to inspect all aspects of a network's Cisco infrastructure to collect the following information:
