12 Leaf-Spine Deployment and Best Practices Guide | Version 1.0
4 Management network
The OOB management network is isolated from the leaf-spine production network. It is the same for the layer
2 and layer 3 leaf-spine topologies.
An S3048-ON installed in each rack provides 1GbE connectivity to the management network. The RJ-45
OOB management ports on each spine and leaf switch are connected to the S3048-ON switches as shown in
Figure 9. PowerEdge server iDRACs and Chassis Management Controllers (CMCs) are also connected for
server administration.
For the S3048-ON management switches, all ports used are in layer 2 mode and are in the default VLAN.
Rapid Spanning Tree Protocol (RSTP) is enabled as a precaution against loops. No additional configuration is
required.
Note: The management network used in the examples in this guide is 100.67.187.0/24.

Note: A management network is not a requirement to configure or use a leaf-spine network, but is
recommended to efficiently manage servers, switches and storage devices.
