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 via their dedicated hardware management ports. It is also commonly used to
carry heartbeat messages sent between switches configured as VLT peers.
For OOB management 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 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: This is not to be confused with the in-band management network which runs on the same physical
network as other VxRail and end-user traffic. In-band connections are covered in Section 3.
Devices on the OOB management network in this guide use the 100.67.0.0/16 IP address block.
