You can use J-Web Quick Configuration
to quickly configure redundant Ethernet (reth) interfaces.
A redundant Ethernet interface is a pseudo interface that manages
two “child” physical interfaces, one on each node of
the cluster. Configuration parameters set for a redundant Ethernet
interface are inherited by its child interfaces. A redundant Ethernet
interface allows the chassis cluster to share one IP address across
two links. When a redundancy group that the redundant Ethernet interface
belongs to fails over, its redundant Ethernet interfaces fail over
with it and their interfaces on the new node become active.
Note:
Before configuring redundant Ethernet interfaces, you must specify
the reth-count so that reth interfaces will show in the configuration
or J-Web interfaces screen. For example, to specify that there will
be five redundant Ethernet interfaces, enter:
Click an interface name by which to group physical Ethernet
interfaces for redundancy. See Figure 58.
To add an interface to a redundant Ethernet interface,
click Add.
Fill in the parameter settings for the logical interfaces
as described in Table 48. For details, see the JUNOS Software Interfaces and Routing Configuration Guide.
Fill in the information for Redundant Parent to
specify the redundant parent Ethernet interface of the child physical
interface.
To apply the configuration and stay on the Quick Configuration
page, click Apply.
To apply the configuration and return to the main Configuration
page, click OK.

Logical Interfaces
Add Logical Interfaces
Defines one or more logical units that you connect to this physical
redundant Ethernet interface. You must define at least one logical
unit for a redundant Ethernet interface.
Click Add.
To delete a logical interface, select the check box corresponding
to the interface you want to delete and click Delete.
High Availability
Redundancy Number
Specifies the number of the redundancy group to which the redundant
interface belongs. Failover properties of the interface are inherited
from the redundancy group.
Select a number from 0 through 225.
Loop Back
Enables or disables the loopback option.
By default, the loopback is disabled. Select Yes to
enable loopback mode.
Flow Control
Enables flow control on the Ethernet interface.
Select Yes.
Sources Filtering
Enables the filtering of media access control (MAC) source addresses
to block all incoming packets to that interface.
By default, the source address filtering is disabled. Select Yes.
Redundant Parent
Specifies the name of the redundant Ethernet interface that
a physical interface is associated with to form a redundant Ethernet
interface pair.
