•
eth2—The eth2 interface is reserved for future use.
• eth3—Use the eth3 interface as the device management interface for SSH access to
managed devices when the managed devices are on an out-of-band management
subnet or on a subnet not accessible through the eth0 interface.
NOTE:
• If the managed devices are not accessible 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.
• When the eth3 interface is configured as a device management interface,
Junos Space Platform does not forward ICMP packets through the eth3
interface. To allow ICMP packets through the eth3 interface, routes must
be added manually.
•
When you configure an appliance as a Junos Space node, you can configure the Ethernet
interfaces as follows:
• Configure only the eth0 interface.
When only 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.
• Configure the eth0 and eth3 interfaces.
When Ethernet interfaces eth0 and eth3 are used, the Junos Space nodes in the
fabric and VIP address of the fabric are on the same subnet and are reachable through
Ethernet interface
ETH0
(JA1500 appliance) or 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
ETH0 or Ethernet
interface 0 , and are reachable through Ethernet interface ETH3 (JA1500 appliance)
or Ethernet interface 3 (JA2500 appliance).
• Configure the eth0 and eth1 interfaces.
When Ethernet interfaces eth0 and eth1 are used, the Junos Space nodes in the fabric
and the VIP address of the fabric may or may not be on the same subnet. The eth1
interface provides SSH access to the Junos Space nodes.
The VIP address and the devices being managed by Junos Space are on the same
subnet.
•
Configure the eth0, eth1, and eth3 interfaces.
When Ethernet interfaces eth0, eth1, and eth3 are used, the Junos Space nodes in
the fabric and the VIP address of the fabric may or may not be on the same subnet.
The Junos Space nodes are reachable (SSH access) only through the eth1 interface.
The managed devices can be reached through the eth0 interface if they are configured
on the same subnet as the VIP address; on any other subnet, the managed devices
can be reached through the eth3 interface.
