10 Example 4: Layer 2 with Dell EMC leaf and Cisco Nexus
spine switches
This section provides configuration information to build the layer 2 leaf-spine topology shown in Figure 17.
Dell EMC Networking Z9100-ON switches are used at the leaf layer and Cisco Nexus 7000 series switches
are used at the spine layer.

Example 4: Layer 2 leaf-spine topology with Dell EMC leaf and Cisco Nexus spine switches
Note: All switch configuration files for the topology in Figure 17 are contained in the attachment named
Example4_config_files.pdf. The files may be edited as needed in a plain text editor and commands pasted
directly into switch consoles.
Dell EMC Networking switches start at their factory default settings per Appendix A.
Cisco Nexus switches in this example were reset to their factory default configurations by running write
erase followed by reload. After reload, "Power on Auto Provisioning" was not used, the admin password
was configured and the Nexus “basic configuration dialog” was not used. Refer to your Nexus system
documentation for more information.
