Configuring Redundant Ethernet Interfaces—Quick Configuration

You can use J-Web Quick Configuration to quickly configure redundant (reth) Ethernet 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.

To configure redundant Ethernet interfaces with Quick Configuration:

Select Configuration>Quick Configuration>Interfaces.
Click an interface name to group physical Ethernet interfaces for redundancy. See Figure .
To add an interface to a redundant Ethernet interface, click Add.
Fill in the parameter settings for the logical interfaces as described in Table . For details, see the JUNOS Software with Enhanced Services Interfaces and Routing Configuration Guide.
Fill in the redundant Ethernet interface information, specifying the parent redundant Ethernet interface of the child physical interface as the redundant Parent.
- To apply the configuration and stay on the current Quick Configuration page, click Apply.
- To apply the configuration and return to the previous Quick Configuration page, click OK.
- To cancel your entries and return to the previous Quick Configuration page, click Cancel.

Field	Function	Your Action
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.
Chassis Cluster
Redundancy Number	Specifies the number of the redundancy group that the redundant interface belongs to. 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.
