This section describes the following:

- How to add an IPAM Sync configuration.
- How to edit an IPAM Sync configuration.
- How to delete an IPAM Sync configuration.

To add a sync configuration, complete the following:

1. Go to the **Settings** icon > **Setup** > **NIOS IPAM Sync**.
2. Click **Add ****Sync ****Configuration**.  
The **Sync configuration wizard** dialog box opens.
3. In **Step ****1** of the Wizard, enter the NIOS Grid Master IP address or host name, with username and password. For standalone NIOS deployments, enter the IP address or host name of the NIOS device. The default login credentials are admin/infoblox.
4. Click **Next**.  
Make sure the NIOS system is reachable before attempting a connection, and ensure you have the correct admin account and password. The specified username and password also must provide access to the Infoblox DMAPI (Data and Management API). Any NIOS administrator account can be set to allow API access from within NIOS with an Allowed Interfaces setting of API. Consult the *Infoblox API Documentation *guide for the version of NIOS in the current operation for more details, and consult the *NIOS Administration Guide *for the procedure on defining API interface access for an admin account.
5. In **Step ****2**, in **NS1 Network View**, select **default** as the view to which to export data. This information is obtained from the Infoblox Grid Master.
6. In **NetMRI Network View**, select the required view.
7. In **Time restriction**, select **Include all data, regardless of polling time**.> Macro (inline-media-image)

In the versions prior to 7.3.1, NetMRI sent data collected from devices that were successfully polled within the last two hours. This restriction was removed in version 7.3.1. You can request to export all data regardless of the last successful device polling time or data from devices successfully polled in the last several hours.
8. Select **Synchronize ****Device ****Information** if you want to include devices (IP addresses) in the synchronization.
9. If you enabled the synchronization of device information and you want to include end host IP addresses into NIOS IPAM Sync, select **Include addresses from ARP tables**.   
By default, only routers IP addresses are included in NIOS IPAM Sync. Selecting this option allows you to export IP addresses of end hosts from ARP tables of discovered devices to NIOS IP Map, along with routers IP addresses. These end hosts are listed in a separate tab in NetMRI: **Network Explorer** > **Switch Port Management** > **End Hosts** > **End Host Present**. If the discovery engine does not recognize a device as an infrastructure or network device, it is treated as end host. Data displayed for end hosts collected from ARP tables includes the IP address, MAC address, and Last Discovered and First Discovered stamps.  
Retrieving end hosts IPs based on ARP entries does not guarantee accurate results as the lifetime of ARP tables entries on network devices is very limited (e.g., up to 5 minutes officially, 10 minutes in real life for Cisco IOS-based devices) and the amount of tables entries is relatively small.
10. To add internal subnets as networks in NIOS, activate the **Add ****IPAM** **networks** **for ****subnets ****within ****NetMRI ****discovery** **ranges** option. This will export subnets discovered by NetMRI and classified as internal (i.e., within the defined discovery ranges). To export all internal subnets, select the **All** option. To limit the exported internal subnets, select the **Restrict** **to** **subnet s** **within** **the** **following** **summary** **routes** option, and enter a list of summary routes. Separate each route with a comma, or put each on a new line. Subnets within a listed summary route are exported. For example, to export only the subnets in a class A 10 network, enter 10.0.0.0/8.
11. To add external subnets as networks in NIOS, activate the **Add** **IPAM** **networks ****for ****subnets ****outside** **of ****NetMRI ****discovery ****ranges** option. This will export subnets discovered by **NetMRI** and classified as external (i.e., outside the defined CIDR blocks). To export all external subnets, select the **All** option. To limit the exported external subnets, select the **Restrict** **to** **subnets ****within** **the** **following** **summary ****routes** option, and enter a list of summary routes as described above for internal subnets.
12. Click **Next**.
13. In **Step 3**, if you want to schedule synchronization, select **Schedule Enabled**. This is optional. If you do not schedule a synchronization, you can execute a synchronization at any time. For information, see the next section.
14. Select a **Recurrence** **Pattern**, **Execution ****Time**, and **day** (this is the starting day for repetitive synchronizations).
15. Click **Next**.
16. In **Step** **4**, review the sync configuration. Click **Previous** if you need to change any changes.
17. Click **Finish**.

Now you can run the configured synchronization between NetMRI and NIOS. For more information, see the next section, [*<span style="color: #0000ff"><u>Synchronizing Between NetMRI and NIOS Appliance</u></span>*](https://infoblox-docs.atlassian.net/wiki/spaces/netmri761/pages/1056870210)*<span style="color: #0000ff"><u>s</u></span>*.

To edit a sync configuration, perform the following:

1. Go to the **Settings** > **Setup** > **NIOS IPAM Sync**.
2. Click the** Actions** icon for the required sync configuration and then choose **Edit**.   
A summary of the current configuration appears.
3. Click **Edit**.  
The **Sync** **configuration** **wizard** appears. See the procedure for adding a sync configuration above for the wizard steps.

To delete a sync configuration, complete the following:

1. Go to the **Settings** > **Setup** > **NIOS IPAM Sync**.
2. Click the **Actions** icon for the required sync configuration and then choose **Delete**.
3. In the **Delete Configuration** dialog box, click **OK**.

To exclude devices with unmapped VRFs from IPAM sync, complete the following:

1. Go to the **Settings** icon > **General Settings** > **Advanced Settings**.
2. In the **IPAM Sync** group, click the** Action** icon for the **Exclude Devices with Unmapped VRFs** setting and then choose **Edit**.
3. In the **Editing Setting Exclude Devices with Unmapped VRFs** dialog box, choose **on **and then click **OK**.
