The PowerSwitch S5248F-ON ToR switches support the database public and private interconnect traffic. They also support the database backup and recovery traffic by providing the interconnectivity between the database servers and the Data Domain backup appliance.
This section provides the recommended configuration of the S5248F-ON ToR switches to support the solution. Your environment might require additional configuration, including configuring the communication to the core data center network. For detailed configuration instructions, see the switch configuration guides at PowerSwitch S5248F-ON on Dell EMC Online Support.
Configure the S5248F-ON ToR switches as follows, in accordance with recommended best practices.
Caution: Ensure that the personnel who are responsible for network management in your environment have reviewed the Spanning Tree Protocol (STP) configuration. Incorrect settings might cause network issues. The values that are provided here are examples only.
Note: The management IP address on the two switches is also used as the VLT backup link.
VLT provides a loop-free environment by presenting two physical switches as one logical switch while not losing bandwidth for the devices connecting to it over two separate links.
A default bridge priority value of 32768 or higher ensures that neither of the ToR switches becomes the root bridge when plugged in to the core data center network.
The following tables show an example of a VLAN configuration for the different traffic types:

Perform the following tasks on each of the S5248F-ON switches:
The following figure shows the console and management ports on the back of the switch. The console port is on the upper right near the fans and power supplies.

The Virtual Link Trunking interconnect (VLTi) heartbeat uses the management interface on the back of the PowerSwitch S5248F-ON switch. Each S5248F-ON switch is connected to the S4148T-ON switch with a Cat 5e Ethernet network cable. To configure the management interface, enter configuration mode on each switch and follow these steps:
SW1(config)# interface mgmt 1/1
SW1(conf-if-ma-1/1/1)# no ip address dhcp
SW1(conf-if-ma-1/1/1)# ip address 172.90.100.252/24
SW2(conf-if-ma-1/1/1)# no ip address dhcp
SW2(conf-if-ma-1/1/1)# ip address 172.90.100.253/24
SW1(conf-if-ma-1/1/1)# exit
Caution: Ensure that the personnel who are responsible for network management in your environment have reviewed the configuration for STP. Incorrect settings might cause network issues. The values that are provided here are examples only.
SW1(config)# spanning-tree mode rstp
SW1(config)# spanning-tree rstp priority 16384
SW2(config)# spanning-tree mode rstp

This section describes how to configure the VLANs on the S5248F-ON switches. The examples show how to configure each VLAN in the site survey. Server NIC ports 1 and 2 are used for all traffic. If your configuration does not use spine/leaf network architecture or if you do not want VLAN traffic to be routed by the S5248F-ON switches, skip the commands in bold italics.
Follow these steps on each S5248-ON switch:
