OOB management topology

  • The out-of-band (OOB) management network is an isolated network for remote management of hardware. This includes VxRail nodes, servers, switches, storage arrays, and rack power distribution units (PDUs) using their dedicated management ports.

    For OOB management network connections, one N3248TE-ON switch is installed in each rack, as shown in the figure below.

    The OOB management network is required to access the SFS web UI. It also enables switch console access using SSH, and VxRail node console access using the iDRAC. This network is also used to carry heartbeat messages between switches configured as VLT peers, and for OpenManage Network Integration (OMNI) to communicate with the SFS leader switch.

    Note: OOB management switches are not part of the SmartFabric.

    Note: This guide covers the equipment shown in Racks 1 and 2. Other devices and racks shown in the figure above are for demonstration purposes only.

    Four 10 GbE SFP+ ports are available on each N3248TE-ON for use as uplinks to the OOB management network core.

    1 GbE BASE-T ports on each N3248TE-ON are connected downstream to hardware management ports on each device in the rack. This includes the VxRail node iDRAC ports and switch management ports. Management ports on other devices, such as PowerEdge server iDRAC ports, storage array management ports, and rack PDU management ports, are also connected to this network.

    OOB management switch configuration is not detailed in this guide. The N3248TE-ON can function as an OOB management switch with its OS10 factory default configuration. By default, all ports are in switchport mode, in VLAN 1, administratively up, and rapid per-VLAN spanning tree plus (RPVST+) is enabled.

    Note: At a minimum, Dell Technologies recommends changing the admin password to a complex password during the first login.

    Note: For reference, devices on the OOB Management network in this guide use the 100.67.0.0/16 IP address block. These addresses are examples only. Use IP addresses that are suitable for your environment.
