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:

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


GUI interface with an instance of JBOSS running (GUI)


Not supported


Not supported


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:
