Junos Space Ethernet Interfaces Overview

8
This topic applies to the following Junos Space Appliances: JA1500 and JA2500.
A Junos Space Appliance has four Ethernet interfaces; two interfaces can be used and
two are reserved for future use. The Ethernet interfaces are labeled
and ETH3 for the JA1500 Junos Space Appliance, and
Space Appliance.
When you configure an appliance as a Junos Space node, you can use only one or both
Ethernet interfaces:
When only one Ethernet interface (eth0) is used, the Junos Space nodes in the fabric,
virtual IP (VIP) address of the fabric, and the devices being managed by Junos Space
are on the same subnet.
When both Ethernet interfaces (eth0 and eth3) are used, the Junos Space nodes in
the fabric and virtual IP (VIP) address of the fabric are on the same subnet and are
reachable through Ethernet interface
0 (JA2500 appliance). The devices being managed by Junos Space are on the same
subnet, which is different from the one reachable through Ethernet interface
or Ethernet interface
0
appliance) or Ethernet interface
When you configure an appliance as a specialized node used for fault monitoring and
performance monitoring (FMPM), you can use only the Ethernet interface eth0.
NOTE: For more information about the Junos Space fabric, refer to the Fabric
Management chapter in the Junos Space Network Management Platform User
Guide (available at
http://www.juniper.net/techpubs/en_US/release-independent/junos-space/index.html
The device management interface (eth3) is designed for use in a device management
subnet when the managed devices are not reachable using the eth0 interface or are on
an out-of-band management subnet. The eth3 interface uses the devint routing table
for routing. The devint routing table contains the IP address of the default gateway for
device management traffic and is enabled when the eth3 interface is configured.
NOTE: If the managed network is not reachable through the default gateway,
you must configure static routes.
Any static route configured manually is populated in the main routing table,
which is used to route traffic through the eth0 interface.

Appliance.
