Configuring Redundant Ethernet Interfaces—Quick Configuration
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.
Figure 20 shows the Interface
page.

Figure 21 shows the Redundant Ethernet Interface Configuration page.

Interface Configuration page
To configure redundant Ethernet interfaces with
J-Web Quick Configuration:
- Select Configuration > Quick Configuration > Interfaces.
- Click an interface name to group physical Ethernet interfaces
for redundancy. See Figure 21.
- To add an interface to a redundant Ethernet interface,
click Add.
- Fill in the parameter settings for the logical interfaces
as described in Table 27. 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 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.
|
Specify a redundant Ethernet interface name.
