Configuring IP addresses over Ethernet Interfaces

Perform the following steps to configure IP addresses over the network interfaces which you plan to configure under LLT. These interfaces must not be aggregated interfaces.

  1. Configure IP addresses using Linux ifconfig command. Make sure that the IP address for each link must be from a different subnet.

    Typical private IP addresses that you can use are:

    Node0:

    link0: 192.168.1.1

    link1: 192.168.2.1

    Node1:

    link0: 192.168.1.2

    link1: 192.168.2.2

  2. Run IP ping test between nodes to ensure that there is network level connectivity between nodes.
  3. Configure IP addresses to start automatically after the system restarts or reboots by creating a new configuration file or by modifying the existing file.

    • On RHEL, modify the /etc/sysconfig/network-scripts/ directory by modifying the ifcfg-eth (Ethernet) configuration file.

    • On SUSE, modify the /etc/sysconfig/network/ by modifying the ifcfg-eth (Ethernet) configuration file.

      For example, for an Ethernet interface eth0, create the ifcfg-eth0 file with values for the following parameters. 

      DEVICE=eth0
BOOTPROTO=static
IPADDR=192.168.27.1
NETMASK=255.255.255.0
NETWORK=192.168.27.0
BROADCAST=192.168.27.255
NM_CONTROLLED=no # This line ensures IPs are plumbed correctly after bootup
ONBOOT=yes
STARTMODE='auto' # This line is only for SUSE
