7.3 Single switch
This example uses a four-node VxRail cluster connected to a single switch, as shown in Figure 14.

and 1/1/10.
Four-node cluster connected to a single switch
The commands in the following sections are run to complete the switch configuration. The port numbers used
in the configuration commands correspond to those shown in Figure 14.
Note: The commands in the tables below should be entered in the order shown. All commands are provided
in the file attachment named S5248F-single-switch.txt.
7.3.1 General settings
Configure the hostname, OOB management IP address, and default gateway. Enable IPv6 MLD snooping to
allow discovery of the VxRail nodes. Specify an NTP server accessible by the switch. In this example, this is
an NTP server on the OOB management network, with a different IP address than the one used by the VxRail
nodes on the External Management network.
Note: Default spanning tree settings are used in this deployment. In SmartFabric OS10, RVPST+ is enabled
by default, and RPVST+ VLAN priority numbers start at 32769. Modify the spanning tree settings if required
for your environment. LLDP is enabled on each interface and globally by default. LLDP is useful for
troubleshooting and validation. Dell EMC recommends leaving it enabled.
