Configuring a Junos Space Appliance as a Junos Space Node
You can configure a Junos Space Appliance as a Junos Space node or as a specialized node used for fault monitoring and performance monitoring (FMPM). To configure a Junos Space Appliance as a Junos Space node, you must configure basic network and system settings to make the appliance accessible on the network.
From Junos Space Network Management Platform Release 14.1R2 onward, you can configure Junos Space Ethernet interfaces with only IPv4 addresses, or both IPv4 and IPv6 addresses.
From Junos Space Network Management Platform Release 16.1R1 onward, you can configure access to Junos Space through a Network Address Translation (NAT) gateway.
The disk space allocation for a JA2500 Junos Space Appliances is as follows:
1.2 TB for /var
715 GB for /var/log
92 GB for /tmp
92 GB for /
Before you begin, do the following:
Ensure that the Junos Space Appliance is connected to a management console and that the management device is powered on.
Ensure that the appliance is booted and displays the login prompt at the console.
Ensure that you have the following information available:
IPv4 address and subnet mask for the node management (eth0) Ethernet interface
(Optional) IPv6 address and prefix for the eth0 Ethernet interface
IPv4 address of the default gateway for the eth0 Ethernet interface
(Optional) IPv6 address of the default gateway for the eth0 Ethernet interface
IPv4 address of the name server
(Optional) IPv6 address of the name server
(Optional) IPv4 address and subnet mask for the Ethernet interface eth3, if you are configuring a device management interface
Note:When you configure the eth3 interface as the device management interface, the IP addresses of the eth0 and eth3 Ethernet interfaces must be in different subnets.
(Optional)IPv4 address of the default gateway for the eth3 Ethernet interface
Note:If you configure the IPv4 address for the eth3 Ethernet interface, you must configure the IPv4 address of the default gateway.
(Optional) IPv6 address and prefix for the eth3 Ethernet interface
(Optional) IPv6 address of the default gateway for the eth3 Ethernet interface
Note:If you configure the IPv6 address for the eth3 Ethernet interface, you must configure the IPv6 address of the default gateway for the eth3 interface.
Virtual IP (VIP) address in IPv4 and IPv6 formats
The IPv4 format of the VIP address is used for accessing the Junos Space Network Management Platform GUI through a Web browser. This IP address must be in the same subnet as the IP address assigned to the eth0 Ethernet interface
The IPv6 format of the VIP address is used for receiving SNMP traps from managed devices.
IPv4 address or URI of the NTP source to synchronize time
(Optional) IPv4 address of the eth1 Ethernet interface
If the IP address of the eth1 interface is not in the same subnet as the VIP address, ensure that you have the subnet mask and the default gateway for the eth1 interface.
(Optional) IPv4 address for the NAT outbound SSH
(Optional) IPv6 address for the NAT outbound SSH
(Optional) IPv4 port number for the NAT outbound SSH
(Optional) IPv6 port number for the NAT outbound SSH
(Optional) IPv4 address for the NAT trap
(Optional) IPv6 address for the NAT trap
(Optional) IPv4 port number for the NAT trap
(Optional) IPv6 port number for the NAT trap
This topic discusses the following tasks:
Configuring a Junos Space Appliance as a Junos Space Node
You can configure the Junos Space Appliance as a Junos Space node.
To configure a Junos Space Appliance as a Junos Space node:
If you have specified that the Junos Space node is the first node in the fabric or a standalone node, you can access Junos Space Network Management Platform by typing the IP address configured for the Web GUI in a browser.
If you have specified that the Junos Space node is part of an existing cluster (fabric), then you must add the Junos Space node to the Junos Space fabric using the Junos Space Network Management Web GUI. For more information, see the Adding a Node to an Existing Junos Space Fabric topic in the Junos Space Network Management Platform Workspaces Feature Guide (available at http://www.juniper.net/techpubs/en_US/release-independent/junos-space/index.html).
Configuring Access to Junos Space Through a NAT Gateway
You can choose to configure access to Junos Space through a NAT gateway when you are configuring a Junos Space appliance.
When prompted, specify whether you want to configure access to Junos Space using NAT.
Do you want to enable NAT service ? [Y/N]
To configure NAT, type Y.
Note:If you choose to configure NAT, the options that are displayed depend on the IP address or addresses that you have configured for the device management interface. If you have configured eth3 as the device management interface, then the options that are displayed will depend on the IP address or addresses configured for eth3. If eth3 is not configured, the displayed options will depend on the IP address configuration of the eth0 interface.
If the device management interface is assigned an IPv4 address, you are prompted to enter the IPv4 address for the NAT interfaces. If the device management interface is assigned an IPv6 address, you are prompted to enter the IPv6 address for the NAT interfaces. If the device management interface is assigned an IPv4 address and an IPv6 address, you are prompted to select either IPv4, IPv6, or both for the NAT interfaces.
If you are adding the node to an existing cluster and eth3 is configured, you are prompted to specify whether you want to configure the trap interface. You must choose to configure the trap interface, if you are adding the node as the standby VIP node. If eth3 is not configured for the node, you are not prompted to configure the trap interface.
You are prompted to configure NAT IP addresses.

Configuring the eth1 Interface
From Junos Space Network Management Platform Release 14.1R1 onward, you can configure the eth1 Ethernet interface as an administrative interface. Configure the eth1 interface when the Junos Space node reboots after the basic configuration is complete.
The eth1 interface must be configured separately for each node in a multinode fabric.
If you configure the eth1 interface, SSH is disabled on the eth0 and the eth3 interfaces. You can then access the CLI of the Junos Space appliance only through the eth1 interface.
To configure the eth1 interface:
To troubleshoot issues in configuring the eth1 interface, refer to the /var/log/changeEth1.log file.
