Dell Technologies has provided sample switch configuration files in GitHub at dell-esg/openshift-bare-metal. These files enable you to easily configure the switches that are used for the OpenShift Container Platform cluster. This chapter describes how to customize these configuration files.
Note: Clone the repository using git clone https://github.com/dell-esg/openshift-bare-metal.git and change to the examples directory.
CAUTION: If you use different hardware or need different configurations, modify the configuration files accordingly.
Configuration instructions use certain typographical conventions to designate commands and screen output.
Command syntax is identified by Courier New font. Information that is specific to your environment is placed inside <> symbols and in italics. For example:
Screen output is in Italic Courier New type. Any user action or commands are in Courier New.
Dell EMC PowerSwitch S5232F switches are in Virtual Link Trunking (VLT) mode and uplinked to core switches in the environment. PowerSwitch S3048 has an uplink to S5232F switches. The following table shows the port connections between switches. These connections are reflected in the sample switch configuration files.
