    Modifying the Network Settings of a Node in the Junos Space Fabric

    The Junos Space fabric consists of one or more nodes. Network settings for these nodes enable IP connectivity to external systems as well as internal connectivity between nodes. A Junos Space hardware appliance or a Junos Space virtual appliance is configured as a Junos Space node or a Fault Monitoring and Performance Monitoring (FMPM) node using the Junos Space CLI. You can modify the previously configured settings using the Space Node Settings page.

    Note: The settings for the hosted virtual machine can also be modified using the Space Node Settings page. For a hosted virtual machine, you can modify the IP address, the subnet mask, and the gateway IP address.

    To access the Space Node Settings page, navigate to Administration > Fabric > Space Node Settings. Changing node settings enables you to move the Junos Space fabric from one network location to another location and does not require any reinstallation but only a reboot.

    Note: Before you modify the network settings, note the following:

    • The virtual IP (VIP) address of the Junos Space fabric and the IP address of the Junos Space nodes must be in the same subnet.
    • The database VIP address and the node management IP address of the database nodes must be in the same subnet as the VIP address of the fabric.
    • The node management IP addresses of all Junos Space nodes in the fabric must be in the same subnet.
    • The node management IP addresses of all FMPM nodes in the fabric must be in the same subnet.
    • When you modify the device management IP address, all devices that are connected to Junos Space through device-initiated connections must be updated with the new device management IP address by updating the trap target and the outbound-ssh configuration with the new device management IP address.
    • After you modify the network settings for a node, the node must be rebooted in order for the settings to take effect. Junos Space asks you to confirm the reboot and, upon confirmation, reboots the node and applies the new settings.
    • If you modify the settings of a Junos Space node, then all Junos Space nodes in the fabric are rebooted; the FMPM nodes in the fabric are not rebooted. If you modify the settings of an FMPM node, then only the FMPM nodes in the fabric are rebooted; the Junos Space nodes are not rebooted.

    This topic includes the following sections:

    Modifying the Fabric Virtual IP Address

    To modify the virtual IP (VIP) address of the fabric:

    Note: You can modify the IPv4 VIP address, the IPv6 VIP address, or both.

    Note: You can modify the database VIP address of dedicated database nodes by selecting the primary database node and modifying the required fields in the Node Management Interface section of the Space Node Settings page. See Modifying the Network Settings of a Node.

    1. On the Junos Space Network Management Platform UI, select Administration > Fabric > Space Node Settings.

      The Space Node Settings page is displayed.

    2. In the Fabric Virtual IP field, modify the IPv4 VIP address of the fabric.
    3. In the Fabric Virtual V6 IP field, modify the IPv6 VIP address of the fabric.
    4. Click Confirm.

      The Network Settings Change confirmation dialog box appears.

    5. Click Yes to save the changes.

      The Reboot Node dialog box appears requesting you to enter a reason for the reboot.

      Note: If you do not want to save the changes, click the No button on the Network Settings Change confirmation dialog box.

    6. Enter the reason for the reboot and click OK.

      The nodes are rebooted and the new settings take effect. You can verify that the settings have changed when the nodes are in the UP state.

    Modifying the Network Settings of a Node

    Note: Before you modify the network settings of a node, ensure the following:

    • For Junos Space nodes, the node management IP address and the VIP address must be in the same subnet.
    • For FMPM nodes, the node management IP address and the FMPM VIP address must be in the same subnet.
    • The IPv4 and IPv6 addresses that you use must be valid addresses. Refer to http://www.iana.org/assignments/ipv4-address-space for the list of restricted IPv4 addresses and http://www.iana.org/assignments/ipv6-address-space for the list of restricted IPv6 addresses.
    • All nodes in the Junos Space fabric must have the same type of IP address (or addresses) configured. For example, if a Junos Space node or an FMPM node in a fabric is configured with both IPv4 and IPv6 addresses, then all other Junos Space and FMPM nodes in the fabric must be configured with both IPv4 and IPv6 addresses.

    To modify the network settings of a node:

    1. On the Junos Space Platform UI, select Network Management Platform > Administration > Fabric > Space Node Settings.

      The Space Node Settings page is displayed. The nodes that are part of the fabric are displayed in a table.

    2. Click the pencil icon corresponding to the node (or double-click the node) for which you want to modify the settings.

      The network settings for the node are displayed below the row corresponding to the node. The node management interface and device management settings are grouped in the Node Management Interface and Device Management Interface sections of the Space Node Settings page.

      Note: If you have configured the node with only the IPv4 address, you can use this procedure to modify the IPv4 address as well as add an IPv6 address to the node.

    3. To modify the node management interface settings:
      1. In the IP field, enter the IPv4 address (in dotted-decimal notation) of the node.
      2. In the Netmask field, enter the subnet mask (in dotted-decimal notation) for the node.

        Note: The prefix length range for IPv4 addresses is 1 through 32.

      3. In the Gateway field, enter the IPv4 address of the default gateway.
      4. In the IPv6 field, enter the IPv6 address of the node.
      5. In the Prefix field, enter the IPv6 prefix of the node.

        Note: The prefix length range for IPv6 addresses is 1 through 128.

      6. In the Gateway field, enter the IPv6 address of the default gateway.
    4. To modify the database VIP address:

      Note: The databaseVIP and databaseV6VIP fields appear only when you select the primary database node for modifying the network settings.

      1. In the databaseVIP field, enter the IPv4 VIP address of the database.
      2. In the databaseV6VIP field, enter the IPv6 VIP address of the database.
    5. To modify the device management interface settings:
      1. To enable or disable a separate device management interface:
        • Select Enable Device Interface to enable a separate device management interface.

          Note:

          • On a Junos Space fabric with two or more Junos Space nodes, if you configure the device management interface on one Junos Space node, then you must also configure the device management interface on all the other Junos Space nodes in that fabric.
          • The device management IP addresses for all Junos Space nodes must be in the same subnet.
        • Clear Enable Device Interface to disable a separate device management interface.

          Note: If no device management interface is defined, Junos Space Platform uses the node management interface to communicate with devices.

      2. In the IP field, enter the IPv4 address (in dotted-decimal notation) of the device management interface.
      3. In the Netmask field, enter the subnet mask (in dotted-decimal notation) of the device management interface.

        Note: The prefix length range for IPv4 addresses is 1 through 32.

      4. In the Gateway field, enter the IPv4 address of the default gateway for the device management interface.
      5. In the IPv6 field, enter the IPv6 address of the device management interface.

        Note: The prefix length range for IPv6 addresses is 1 through 128.

      6. In the Prefix field, enter the IPv6 prefix of the device management interface.
      7. In the Gateway field, enter the IPv6 address of the default gateway for the device management interface.
    6. Click OK.

      Junos Space Platform performs a first-level validation of the modified network settings, which might take a couple of minutes:

      • If there are validation errors, an error message is displayed in a dialog box. Click OK to close the dialog box.

        You are taken to the Space Node Settings page. Modify the network settings to ensure that there are no validation errors and repeat this step.

      • If there is no validation error, you are taken to the Space Node Settings page, where the nodes that are part of the fabric are displayed.
    7. Click Confirm to confirm the settings.

      Junos Space Platform performs a second-level validation of the modified network settings, which might take a couple of minutes:

      • If there are validation errors, an error message is displayed in a dialog box. Click OK to close the dialog box.

        You are taken to the Space Node Settings page, where you can modify the network settings to ensure that there are no validation errors and repeat the preceding step.

      • If no validation errors are present, the Network Settings Change confirmation dialog box is displayed.

        1. Click Yes to continue.

          The Reboot Node dialog box appears asking you to enter a reason for the reboot.

        2. Enter the reason for the reboot and click OK.

          Junos Space Platform sends a message to logged-in users, applies the changed network settings, and reboots the node. After the node is rebooted and is in the UP state, the modified network settings can be viewed on the Space Node Settings page.
