Connectivity Guide
28 Dell EMC Networking OS10 Enterprise Edition Switch Configuration Guide for VxRail featuring S5248F-ON,
S5232F-ON and S5148F-ON
7.2.1 General settings
Configure the hostname, OOB management IP address and default gateway. 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 that used by the VxRail nodes on the in-band management network. Enable RSTP
as a precaution against loops. Configure S5148F-Leaf1A as the primary RSTP root bridge using the
spanning-tree rstp priority 0 command and S5148F-Leaf1B as the secondary RSTP root bridge
using the spanning-tree rstp priority 4096 command.
Note: In OS10EE, LLDP is enabled on each interface and globally by default. LLDP is useful for
troubleshooting and validation. Dell EMC recommends leaving it enabled.

7.2.2 Configure VLANs
In this section, VLANs are configured per Table 2.
Create the in-band management VLAN and assign a unique IP address on each switch. Configure VRRP to
provide gateway redundancy. Set the VRRP priority. The switch with the largest priority value becomes the
master VRRP router. Assign the same virtual address to both switches.
Create the vMotion, vSAN, and VM Network VLANs.
