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 N3248TE-ON switch is installed in each rack as shown in the figure below.
The 1 GbE BASE-T ports on each N3248TE-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 10 GbE SFP+ ports are available on each N3248TE-ON for use as uplinks to the OOB management network core.
Devices on the OOB Management network in this guide use the 100.67.0.0/16 IP address block.
