4.2 OOB Management network
The Out-of-band (OOB) Management network is an isolated network for remote management of servers,
switches, and storage devices using their dedicated hardware management ports. It is also commonly used to
carry heartbeat messages sent between switches configured as VLT peers.
For OOB Management network connections, one S3048-ON switch is installed in each rack as shown:

OOB management network connections
Note: This guide focuses on the devices in Rack 1. Devices shown in other racks are for illustration purposes
only.
1GbE BASE-T ports on each S3048-ON are connected downstream to hardware management ports on each
device. This includes VxRail node iDRACs, PowerEdge Server iDRACs, and dedicated management ports on
switches and storage arrays.
Four 10GbE SFP+ ports are available on each S3048-ON for use as uplinks to the OOB management
network core.
Note: The OOB Management network is not to be confused with the External and Internal Management
networks. The External and Internal Management networks and their VLANs are covered in Chapter 5.
Devices on the OOB Management network in this guide use the 100.67.0.0/16 IP address block.
