Configuring a Junos Space Virtual Appliance as a Junos Space Node

 

After you deploy a Junos Space Virtual Appliance on a VMware ESX, VMware ESXi, or Kernel-based Virtual Machine (KVM) server, you must enter basic network and machine information to make your Junos Space Virtual Appliance accessible on the network. You must also add disk space to the partitions of the Junos Space Virtual Appliance.

Before you begin, 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
