You can use J-Web Quick Configuration to quickly
configure redundant Ethernet (reth) interfaces.
A redundant Ethernet interface is a pseudointerface 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.
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:
{primary:node1}
user@host# set chassis cluster reth-count
5
Note that the number of reth interfaces configured
determines the number of redundancy groups that can be configured.
For information about the maximum number of redundant Ethernet interfaces
allowed for each device type, see Table 109.
To configure redundant Ethernet interfaces with
J-Web Quick Configuration:
Select Configure>Interfaces.
Click an interface name by which to group physical Ethernet
interfaces for redundancy. See Figure 173.
To add an interface to a redundant Ethernet interface,
click Add.
Fill in the parameter settings for the logical interfaces
as described in Table 114. 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.
To cancel your entries and return to the main page, click Cancel.

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.
