Configuring network interfaces

You can configure network interfaces on the system. The number and type of interfaces vary according to the specific needs of your system.

Attention: This operation can be performed when the system is powered on as well as powered off. Because network configuration changes occur immediately, existing network sessions, such as HMC connections, are stopped. If a firmware update is in progress, do not perform this operation. The new settings must be used to re-establish any network connections. Additional errors might also be logged if the system is powered on.

You can change the network configurations when the system is in any state.

To perform this operation, you must have one of the following authority levels:
  • Administrator
  • Authorized service provider

To configure network interfaces, do the following steps:

  1. On the ASMI Welcome pane, specify your user ID and password, and click Log In.
  2. In the navigation area, expand Network Services.
  3. Click Network Configuration.
    Important: If you are attempting to configure a network connection on a multi-drawer system, you must select the primary or secondary service processor, and then click Continue.
  4. Specify one of the following network configurations and click Continue:
    • In the Interface Configuration section, click one the following configurations:
      • IPv4
      • IPv6
    • In the Static Route Configuration, click IPv4.
      Note: This settings cannot be done for sibling service processor. For example, if the user is logged in from primary service processor, then this settings cannot be done for secondary service processor
  5. Skip to one of the following steps depending on the networking configuration you specified:
    • If you selected IPv4 in Interface Configuration, Continue with the next step.
    • If you selected IPv6 in Interface Configuration, Continue with step 7.
    • If you selected IPv4 in Static Route Configuration, skip to step 12.
  6. Select Configure this interface to specify the configuration details for the required interface. You can specify the details for eth0 and eth1 network interfaces.
    1. From the IPv4 list, select Enabled.
    2. From the Type of IP address list, select one of the following options:
      Static
      If you select this option, then you must specify the host name, IP address, subnet mask, broadcast address, and the default gateway.
      Dynamic
      No additional input is required.
  7. Select Configure this interface to specify the configuration details for the required interface. You can specify the details for eth0 and eth1 network interfaces.
    1. From the IPv6 list, select Enabled.
    2. From the DHCP list ,sect Enabled.
    3. From the Auto-configured IP address list, select Enabled.
    4. In the Host name field, specify the host name.
  8. Provide the configuration details for the IP addresses.
  9. Provide the following details and skip to step 12
    • Domain name
    • IP address of first DNS server
    • IP address of second DNS server
    • IP address of third DNS server
  10. Select the network interface that you want to configure. You can select eth0 or eth1.
  11. Specify the IP address, Subnet mask, and Gateway address for the network interface.
  12. click Continue to verify the IP settings that you specified.
    Attention: If incorrect network configuration information is entered, you may not be able to use the ASMI after the changes are made. To remedy this situation, you must reset the service processor to the default settings by removing the service processor assembly from the server and moving the reset jumpers. Resetting the service processor also resets all user IDs and passwords to their default values.
    Note: To reset network configuration settings to the default factory settings, click Reset Network Configuration.
  13. Click Save settings to make the changes.
