Understanding How Junos Space Uses Ethernet Interfaces eth0 and eth3

Junos Space is designed to perform best using only eth0 if the managed devices are routable, using in-bound management. Use eth3 for a device management subnet if the managed devices are non-routable or on an out-of-band management subnet.

Table 8 describes how Junos Space interfaces intentionally function:

/Interface

Function

eth0

SSH and device management if eth3 is not configured (node IP)

eth0:0

GUI interface with an instance of JBOSS running (GUI)

eth1

Not supported

eth2

Not supported

eth3

Device management when managed devices are on a subnet and not reacheable by way of eth0.

Junos Space uses eth0 and eth3 interfaces as follows:
