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 virtual appliance is configured as a Junos Space node using the Junos Space CLI. You can modify the previously configured settings using the Space Node Settings page.
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.
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.
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.

Modifying the Fabric Virtual IP Address
To modify the virtual IP (VIP) address of the fabric:
You can modify the IPv4 VIP address, the IPv6 VIP address, or both.
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.
Modifying the Network Settings of a Node
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.
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 in a fabric is configured with both IPv4 and IPv6 addresses, then all other Junos Space nodes in the fabric must be configured with both IPv4 and IPv6 addresses.
