In Multi-Grid Manager, you add and modify IPv4 and IPv6 networks, add extensible attributes and restrict synchronization for network views and networks to manage the network infrastructure of your entire enterprise.

Adding IPv4 and IPv6 Networks

To add an IPv4 or IPv6 network to a specific Grid or Grids:

1. From the Data Management tab, select the IPv4 or IPv6 Map or List panel, and then click the Add icon.

2. In the Add Network wizard, do one of the following to add new networks:

   • IPv6 Prefix: This is displayed only if you are adding an IPv6 network. If you are adding an IPv6 network using a previously defined global IPv6 prefix, you can select it from the list.

   • Address: Enter the network address.

   • Netmask: Adjust the netmask slider to a fixed netmask for this network address.

   • Networks: Add an IPv4 network or an IPv6 network to expand the network.
     Or

   • Click the Next Available icon to have the appliance search for the next available network.

     • Create new network(s) under: Enter the network container in which you want to create the new
       network. When you enter a network that does not exist, the appliance adds it as a network
       container. You can also click Select Network to select a specific network in the Network Selector dialog box. The Network Selector option displays only networks from Grids-NIOS 8.6.5 and later.

     • Number of new networks: Enter the number of networks you want to add to the selected network container. The maximum number is 20 at a time. Note that when you have existing networks in the table and you select one, the number you enter here includes the selected network.

       • Click Add Next to add the networks. Multi-Grid Manager lists the networks in the table.

       • Click Add Next or Cancel.

   • Comment: Enter useful information about the network address.

   • Disable: Select the checkbox to disallow the network from being usable.

3. Click Next and complete the following to delegate the new network to an existing Grid or Grids:

   • Grid: Select the Grid to which you want to delegate the newly created network.

   • Network View: Select the network view to which you want to delegate the network. Click + to delegate the same network to another Grid and network view.

4. Click Next to add extensible attributes.
   To schedule this task, click the Schedule icon at the top of the wizard. In the Schedule Change panel, click Later, and then specify a date, time, and time zone.

5. Save and Close the configuration.

Modifying IPv4 and IPv6 Networks

To modify an IPv4 or IPv6 network:

1. From the Data Management tab, select the IPv4 or IPv6 Map or List panel, and then click the Edit icon.

2. The IPv4 Network or IPv6 Network editor provides the following tabs from which you can modify data:

   • In General Tab:

     • Address: Displays the network address.

     • Netmask: Displays the netmask of the network as you resize the network.

     • Comment: Modify the information about the network address.

     • Disable: You can disable and enable existing networks.

     • Grid: Displays the Grid to which the network block belongs.

     • Network View: The network view to which the network belongs to in the Grid.

   • Extensible Attributes: Modify extensible attributes as described in Entering Extensible Attribute Values.

   • Permissions: Modify the permissions of the network as described in Modifying Permissions.

3. Save the configuration.

Resizing IPv4 Networks

You can resize an IPv4 network to increase or decrease the network size and the number of IP addresses in the network. When you resize a network to a smaller netmask, you increase the number of IP addresses within that network. You can change the size of an IPv4 or IPv6 network when the operation does not affect existing objects in the network. You can resize an existing network only if the network is not assigned to a Grid member. When a network has a parent network or subnets, the upper limit of the network size is marked in red in the resize network slider, and you cannot resize beyond this limit. For example, if a network has a /16 parent network, you cannot resize the network to a network that is larger than /16.
To resize a network:

1. From the Data Management tab, select the IPv4 or IPv6 Map or List panel.

2. Drill down to the network you want to resize, select the network, and then click Resize from the Toolbar. Note that you can only resize networks that are not currently assigned to a Grid member.

3. In the Resize Network editor, do the following:

   • Address: Displays the network address. You cannot modify this field.

   • Netmask: Displays the netmask of the network as you resize the network. You cannot modify this field.

   • Resize slider: Use the resize network slider to specify the appropriate subnet masks for the subnets. When you move the slider, Grid Manager displays the number of subnets and IP addresses within that subnet.

4. Click OK.

Entering Extensible Attribute Values

Multi-Grid Manager displays the required extensible attributes, if any. You must enter values for all required attributes. For more information about extensible attributes, see About Extensible Attributes.
In this step, you can do the following:

• Enter values for extensible attributes

• Add attributes

• Delete non-required attributes

To enter values for extensible attributes:

1. Click the Value column of the attribute.

2. Depending on the required attribute type, either enter or select a value for the attribute from the Value column. You must enter values for all required attributes.

To add attributes:

1. Click the Add icon.
   Grid Manager adds a row to the table with the default attribute displayed.

2. Click the default attribute and expand the list of available attributes.

3. Select an attribute from the drop-down list.

4. Enter or select a value for the attribute from the Value column.

To delete an attribute:

1. Click the checkbox beside the attribute you want to delete.

2. Click the Delete icon.

To delete all attributes:

1. Click the checkbox beside Attribute Name.

2. Click the Delete icon.

Note: You can delete only attributes that are not required. If you have one or more required attributes, you cannot use the delete all function.

Restricting Synchronization

You can restrict synchronization of network views, network containers, and networks from the managed Grid to the Multi-Grid Master. You can do this when you are configuring or modifying them.

Restricting Synchronization for Network Views

To restrict synchronization when adding a new network view:

1. Log in to the managed Grid. Make sure that the Grid remains joined with the Multi-Grid Master.

2. From the Administration tab, select the Network Views tab, and then click the Add icon.

3. In the Network View wizard, do the following:

   • Disable sync to MGM: Select this checkbox to disable synchronization. This will restrict the synchronization of all objects that are associated with this network view.

4. Save the changes.

To restrict synchronization when modifying network views:

1. Log in to the managed Grid. Make sure that the Grid remains joined with the Multi-Grid Master.

2. From the Administration tab, select the Network Views tab -> network_view checkbox, and then click the Edit icon.

3. In the Network View editor, select the General tab and complete the following:

   • Disable sync to MGM: Select this checkbox to disable synchronization. This will restrict the synchronization of all objects that are associated with the selected network view.

4. Save the changes.

Restricting Synchronization on IPv4 and IPv6 Networks at the SubGrid level

When you configure IPv4 or IPv6 networks on the managed Grid, you can enable or disable synchronization, or inherit settings from the parent object. You cannot override the settings at the child level if you have already restricted synchronization at the parent level. You may receive an error message when you try to enable synchronization at the child level after disabling synchronization at the parent level.
To restrict synchronization while configuring IPv4 or IPv6 networks:

1. Log in to the managed Grid. Make sure that the Grid remains joined with the Multi-Grid Master.

2. From the Data Management tab -> IPAM tab.

3. From the Add drop-down menu, select IPv4 Network or IPv6 Network.

4. In the Add Network wizard, select one of the following:

   • Add Network Container: Select this to add a network container.

   • Add Network: Select this to add a network.

5. Click Next and select one of the following from the Sync to MGM drop-down list:

   • Yes: Select this to enable synchronization of networks between the managed Grid and Multi-Grid Master.

   • No: Select this to disable synchronization of networks between the managed Grid and Multi-Grid Master.
     Note: If you have selected No at the parent network (disabled synchronization) and if you try to select Yes when adding a child network, the appliance returns an error. This means that you cannot override the settings at the child level if you have already restricted synchronization at the parent network.

   • Use Inherited Setting: Select this is to inherit synchronization settings from the parent object.

6. Save the changes.

To restrict synchronization while modifying IPv4 or IPv6 networks:

1. Log in to the managed Grid. Make sure that the Grid remains joined with the Multi-Grid Master.

2. From the Data Management tab, select the DHCP tab -> Networks tab -> Networks section -> network checkbox, and then click the Edit icon.
   or
   From the Data Management tab, select the IPAM tab -> network checkbox, and then click the Edit icon.

3. The IPv4 Network editor contains the following basic tabs from which you can modify data:

   • General Basic: You can modify the following fields:

     • Comment: The information you entered for the network.

     • Disabled: This field is displayed only if the selected network is a network without a child network under it. You can disable and enable existing networks instead of removing them from the database, if the selected network does not have a child subnet. This feature is especially helpful when you have to move or repair the server in a particular network.

     • Disable sync to MGM: Click Override and select this checkbox to disable synchronization of the selected network with the Multi-Grid Master. Note that you can override only when you have not disabled synchronization at the parent level.

4. Save the changes.
