Configuring Redundant Ethernet Interfaces—Quick Configuration

Note: For SRX 210 devices, you can configure a maximum of eight redundant Ethernet interfaces.

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:



{primary:node1}
user@host# set chassis cluster reth-count
5

To configure redundant Ethernet interfaces with J-Web Quick Configuration:

Select Configuration > Quick Configuration > Interfaces.
Click an interface name by which to group physical Ethernet interfaces for redundancy. See Figure 27.
To add an interface to a redundant Ethernet interface, click Add.
Fill in the parameter settings for the logical interfaces as described in Table 113. 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.

Table 113: Redundant Ethernet Interface Options

Field	Function	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.
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.	Specify a redundant Ethernet interface name.
