Configuring Redundant Ethernet Interfaces

A redundant Ethernet interface is a pseudointerface that contains two physical interfaces, one from each node of the cluster. To create a redundant Ethernet interface, you configure the two physical interfaces independently. You configure the rest of the configuration that pertains to them at the level of the redundant Ethernet interface, and each of the child interfaces inherits this configuration.

Note: A redundant Ethernet interface is referred to as a reth in configuration commands.

Use the following commands to bind redundant child physical interfaces to reth1:


            
               {primary:node1}
               user@host# set interfaces ge-0/0/0 gigether-options
                     redundant-parent reth1
               {primary:node1}
               user@host# set interfaces ge-7/0/0 gigether-options
                     redundant-parent reth1
               {primary:node1}
               user@host# set interfaces fe-1/0/0 fast-ether-options
                     redundant-parent reth1
               {primary:node1}
               user@host# set interfaces fe-8/0/0 fast-ether-options
                     redundant-parent reth1

Use the following commands to:

Add reth 1 to redundancy group 1.
Set the MTU size to 1500 bytes.
Assign IP address 10.1.1.3/24 to reth1.
{primary:node1} user@host# set interfaces reth1 redundant-ether-options redundancy-group 1 {primary:node1} user@host# set interfaces reth1 unit 0 family inet mtu 1500 {primary:node1} user@host# set interfaces reth1 unit 0 family inet address 10.1.1.3/24

Use the following command to associate reth1.0 with a security zone named Trust. Security zone configuration is the same for redundant Ethernet interfaces as for any other interface.


            
               {primary:node1}
               user@host# set security zones security-zone
                     Trust interfaces reth1.0
