Dell EMC PowerSwitches

Update the input parameters

Under the control_plane/input_params directory, edit the following files:

1. base_vars.yml file: Update the following variable to enable or disable Ethernet switch configurations in the cluster.

   Variable	Default, choices	Description
   ethernet_switch_support	false true	Set the variable to "true" to enable Ethernet switch configurations.

2. login_vars.yml file: Enter the following details to configure Ethernet switches.
   a. ethernet_switch_username- username for Ethernet switches.
   NOTE: The username must not contain the following characters: -, \, "", and \'
   b. ethernet_switch_password- password for Ethernet switches.
   NOTE: Minimum length of the password must be eight characters and the maximum limit is 30 characters. Do not use these characters while entering a password: -, \, "", and \'

3. ethernet_tor_vars.yml or ethernet_vars.yml file: If ethernet_switch_support is set to "true" in the base_vars.yml file, then update the following variables.

   a. Edit the ethernet_tor_vars.yml file for all S3* and S4* PowerSwitches such as S3048-ON, S4048T-ON, S4112F-ON, S4048-ON, S4048T-ON, S4112F-ON, S4112T-ON, and S4128F-ON.

   The interfaces are from ethernet 1/1/1 to ethernet 1/1/52. For more information about the interfaces, see the Supported interface keys of PowerSwitch S3048-ON (ToR Switch) section in the README file. NOTE: The playbooks will fail if any invalid configurations are entered.WARNING: When set to "true", the startup configuration file is updated. If incorrect configurations or commands are entered, the Ethernet switches may not operate as expected.

   Variables	Default, choices	Description
   os10_config	"interface vlan1" "exit"	Global configurations for the switch.
   os10_interface	By default: Port description is provided. Each interface is set to "up" state.	Update the individual interfaces of the PowerSwitch S3048-ON (ToR Switch).
   save_changes_to_startup	false true	Change it to "true" only when you are certain that the updated configurations and commands are valid.

b. Edit the ethernet_vars.yml file for Dell PowerSwitch S5232F-ON and all other PowerSwitches except S3* and S4* switches.

The interfaces are from ethernet 1/1/1 to ethernet 1/1/34. By default, the breakout mode is set for 1/1/1 to 1/1/31. NOTE: The playbooks will fail if any invalid configurations are entered.WARNING: When set to "true", the startup configuration file is updated. If incorrect configurations or commands are entered, the Ethernet switches may not operate as expected.

Variables	Default, choices	Description
os10_config	"interface vlan1" "exit"	Global configurations for the switch.
breakout_value	10g-4x 5g-4x 40g-1x 50g-2x 100g-1x	By default, all ports are configured in the 10g-4x breakout mode in which a QSFP28 or QSFP+ port is split into four 10G interfaces. For more information about the breakout modes, see Configure breakout mode.
os10_interface	By default: Port description is provided. Each interface is set to "up" state. The fanout/breakout mode for 1/1/1 to 1/1/31 is as per the value set in the breakout_value variable.	Update the individual interfaces of the Dell PowerSwitch S5232F-ON.
save_changes_to_startup	false true	Change it to "true" only when you are certain that the updated configurations and commands are valid.

Deploy Omnia Control Plane

Before you configure the Dell EMC PowerSwitches, you must complete the deployment of Omnia control plane. Go to Step 8 in the Steps to install the Omnia Control Plane file to run the ansible-playbook control_plane.yml file.
