Chassis Cluster Redundant Ethernet Interfaces
A redundant Ethernet (reth) interface is a pseudo-interface that includes minimum one physical interface from each node of a cluster. A reth interface of the active node is responsible for passing the traffic in a chassis cluster setup. For more information, see the following topics:
Understanding Chassis Cluster Redundant Ethernet Interfaces
For SRX300, SRX320, SRX340, SRX345, SRX380, SRX1500, SRX1600, SRX2300, SRX4100, SRX4200, and SRX4300 devices, the total number of logical interfaces that you can configure across all the redundant Ethernet (reth) interfaces in a chassis cluster deployment is 1024.
For SRX5800, SRX5600, SRX5400, and SRX4600 devices, the total number of logical interfaces that you can configure across all the redundant Ethernet (reth) interfaces in a chassis cluster deployment is 4096.
Starting with Junos OS Release 12.1X45-D10 and later, sampling features such as flow monitoring, packet capture, and port mirroring are supported on reth interfaces.
A redundant Ethernet interface must contain, at minimum, a pair of Fast Ethernet interfaces or a pair of Gigabit Ethernet interfaces that are referred to as child interfaces of the redundant Ethernet interface (the redundant parent). If two or more child interfaces from each node are assigned to the redundant Ethernet interface, a redundant Ethernet interface link aggregation group can be formed. A single redundant Ethernet interface might include a Fast Ethernet interface from node 0 and a Fast Ethernet interface from node 1 or a Gigabit Ethernet interface from node 0 and a Gigabit Ethernet interface from node 1.
On SRX5600, and SRX5800 devices, interfaces such as 10-Gigabit Ethernet (xe), 40-Gigabit Ethernet, and 100-Gigabit Ethernet can be redundant Ethernet (reth) interfaces.
SRX4100 and SRX4200 devices support 10-Gigabit Ethernet (xe) interfaces as redundant Ethernet (reth) interfaces.
A redundant Ethernet interface is referred to as a reth in configuration
commands.
A redundant Ethernet interface's child interface is associated with the redundant Ethernet interface as part of the child interface configuration. The redundant Ethernet interface child interface inherits most of its configuration from its parent.
The maximum number of redundant Ethernet interfaces that you can configure varies, depending on the device type you are using, as shown in Table 1. The number of redundant Ethernet interfaces configured determines the number of redundancy groups that can be configured in the SRX Series Firewalls.

You can enable promiscuous mode on redundant Ethernet interfaces. When promiscuous mode is enabled on a Layer 3 Ethernet interface, all packets received on the interface are sent to the central point or Services Processing Unit (SPU), regardless of the destination MAC address of the packet. If you enable promiscuous mode on a redundant Ethernet interface, promiscuous mode is then enabled on any child physical interfaces.
To enable promiscuous mode on a redundant Ethernet interface, use the
promiscuous-mode statement at the [edit
interfaces] hierarchy.
A redundant Ethernet interface inherits its failover properties from the redundancy group
x that it belongs to. A redundant Ethernet interface remains active as long
as its primary child interface is available or active. For example, if
reth0 is associated with redundancy group 1 and redundancy group 1
is active on node 0, then reth0 is up as long as the node 0 child of
reth0 is up.
Point-to-Point Protocol over Ethernet (PPPoE) over redundant Ethernet (reth) interface is supported on SRX300, SRX320, SRX340, SRX345, SRX380, SRX1500, and SRX1600 devices in chassis cluster mode. This feature allows an existing PPPoE session to continue without starting a new PPP0E session in the event of a failover.
On SRX300, SRX320, SRX340, SRX345, and SRX380 devices, the number of child interfaces is restricted to 16 on the reth interface (eight per node).
When using SRX Series Firewalls in chassis cluster mode, it is not recommended to configure any local interfaces (or combination of local interfaces) along with redundant Ethernet interfaces.
For example:
The following configuration of chassis cluster with redundant Ethernet interfaces in which interfaces are configured as local interfaces:
ge-2/0/2 {
unit 0 {
family inet {
address 10.1.1.1/24;
}
}
}
The following configuration of chassis cluster redundant Ethernet interfaces, in which interfaces are configured as part of redundant Ethernet interfaces, is supported:
interfaces {
ge-2/0/2 {
gigether-options {
redundant-parent reth2;
}
}
reth2 {
redundant-ether-options {
redundancy-group 1;
}
unit 0 {
family inet {
address 10.1.1.1/24;
}
}
}
}
You can enable promiscuous mode on redundant Ethernet interfaces. When promiscuous mode is enabled on a Layer 3 Ethernet interface, all packets received on the interface are sent to the central point or Services Processing Unit (SPU), regardless of the destination MAC address of the packet. If you enable promiscuous mode on a redundant Ethernet interface, promiscuous mode is then enabled on any child physical interfaces.
To enable promiscuous mode on a redundant Ethernet interface, use the
promiscuous-mode statement at the [edit
interfaces] hierarchy.
IP-over-IP Tunneling
IP-over-IP tunneling is supported over the reth interface in SRX chassis cluster configuration. Tunneling allows the encapsulation of one IP packet over another IP packet.
The tunnel configuration is created on both the primary and secondary devices. The traffic passing through the IP-IP tunnel is synced from primary device to secondary device. The tunnel configuration on secondary device is considered as backup and active in the event of failure of the primary device. The traffic resumes on the secondary device in the event of the failure of the primary.
On SRX Series Firewalls, Generic Routing Encapsulation (GRE) and IP-IP tunnels use internal interfaces, gr-0/0/0 and ip-0/0/0, respectively. The Junos OS creates these interfaces at system bootup; they are not associated with physical interfaces.

Example: Configuring Chassis Cluster Redundant Ethernet Interfaces
This example shows how to configure chassis cluster redundant Ethernet interfaces. A redundant Ethernet interface is a pseudointerface that contains two or more physical interfaces, with at least one from each node of the cluster.
Requirements
Before you begin:
Understand how to set the chassis cluster node ID and cluster ID. See Example: Setting the Chassis Cluster Node ID and Cluster ID.
Set the number of redundant Ethernet interfaces.
Understand how to set the chassis cluster fabric. See Example: Configuring the Chassis Cluster Fabric Interfaces.
Understand how to set the chassis cluster node redundancy groups. See Example: Configuring Chassis Cluster Redundancy Groups.
Overview
After physical interfaces have been assigned to the redundant Ethernet interface, you set the configuration that pertains to them at the level of the redundant Ethernet interface, and each of the child interfaces inherits the configuration.
If multiple child interfaces are present, then the speed of all the child interfaces must be the same.
A redundant Ethernet interface is referred to as a reth in configuration commands.
You can enable promiscuous mode on redundant Ethernet interfaces. When promiscuous mode is enabled on a Layer 3 Ethernet interface, all packets received on the interface are sent to the central point or Services Processing Unit regardless of the destination MAC address of the packet. If you enable promiscuous mode on a redundant Ethernet interface, promiscuous mode is then enabled on any child physical interfaces.
To enable promiscuous mode on a redundant Ethernet interface, use the promiscuous-mode statement at the [edit interfaces] hierarchy.

Results
From configuration mode, confirm your configuration by entering the
show interfaces command. If the output does not display
the intended configuration, repeat the configuration instructions in this
example to correct it.
For brevity, this show command output includes only the
configuration that is relevant to this example. Any other configuration on
the system has been replaced with ellipses (...).
