Keywords:
In this example one active/backup bond will be configured on bridge0 and one active/backup bond will be configured on bridge1.
  1. Connect to the ASP Host server using the services port connection.
  2. Initiate a session to the ASP host using a Secure Shell (SSH) client e.g., PuTTY.
  3. Authenticate using the existing custadm credentials or craft if EASG is enabled.
  4. Execute the following CLI command: configNetwork.
  5. Follow the script prompts:
    1. Type y to continue if the connection is via services port.
    2. Type n to continue (OOBM configuration is not part of this procedure).
    3. Enter the number of bridges to configure: 2.
      ADDITIONAL INFORMATION:
      Note:
      Script automatically detects existing configuration and will display the current value between parentheses.
    4. To configure bridge0 (Management/VM Bridge), type 1 for 1G active/backup bond.
    5. Enter the second port # to use in the bond e.g. 3 for eno12429.
    6. Type n to continue (VLAN configuration is not part of this procedure).
      ADDITIONAL INFORMATION:
      Note:
      Script automatically detects existing configuration and will display the current value between parentheses. If VLAN configuration is detected, to retain current configuration, simply press Enter without making any changes to keep existing setup.
    7. To configure bridge1 (Secondary VM Bridge), type 1 for 1G active/backup bond.
    8. Enter the first port # to use in the bond e.g. 2 for eno12399.
    9. Enter the second port # to use in the bond e.g. 1 for eno12419.
    10. Type n to continue (VLAN configuration is not part of this procedure).
      ADDITIONAL INFORMATION:
      Note:
      Script automatically detects existing configuration and will display the current value between parentheses. If VLAN configuration is detected, to retain current configuration, simply press Enter without making any changes to keep existing setup.
    11. Press Enter key (7 times) until prompt displays Continue with these values? y=continue/n=retry/q=quit (n). If satisfied with current selections type y.
      ADDITIONAL INFORMATION:
      Note:
      Although multiple changes at the same time are supported by the network script, IP address changes are not part of this procedure.
