This section describes a minimal configuration for your Dell EMC Networking S5248F-ON switches to support the Ready Stack. Additional configuration might be necessary for your environment and to configure communication to your core data center network.
If you are not familiar with configuring the Dell EMC Networking S5248F-ON switch, see the S5248F-ON documentation on Dell EMC Online Support.
Configure the S5248F-ON switches:
The following figure shows the console and management ports. The console port is located on the upper right side of the switch when you are looking at the back portion near the fans and power supplies.

SW1(config)# username <username> password <password> role sysadmin

The VLTi heartbeat uses the management interface on the back of the Dell EMC Networking S5248F-ON switch, which is connected with a Cat 5e Ethernet network cable from the top S5248F-ON switch to the bottom S5248F-ON switch. To configure the management interface, go into global configuration mode on the 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 192.168.1.252/24
SW2(conf-if-ma-1/1/1)# no ip address dhcp
SW2(conf-if-ma-1/1/1)# ip address 192.168.1.253/24
SW1(conf-if-ma-1/1/1)# exit
SW1(config)# spanning-tree mode rstp
SW1(config)# spanning-tree rstp priority 16384
SW2(config)# spanning-tree rstp priority 32768
Caution: Ensure that the personnel responsible for network management in your environment have reviewed the configuration for SPT because incorrect settings may cause network issues. The values provided here are examples only.
Configure the ports to be used for VLTi traffic:
SW1(config)# interface range ethernet 1/1/53-1/1/54
SW1(conf-range-eth1/1/53-1/1/54)# description VLTi
SW1(conf-range-eth1/1/53-1/1/54)# no switchport
SW1(conf-range-eth1/1/53-1/1/54)# exit
SW1(config)# vlt-domain 1
SW1(conf-vlt-1)# backup destination 192.168.1.253
SW2(conf-vlt-1)# backup destination 192.168.1.252
SW1(conf-vlt-1)# discovery-interface ethernet 1/1/53-1/1/54
SW1(conf-vlt-1)# do write memory
SW1# show vlt 1 | find Status
The following output appears:

SW1(conf-range-eth1/1/1-1/1/16)# switchport mode trunk
SW1(conf-range-eth1/1/1-1/1/16)# switchport access vlan 100
SW1(conf-range-eth1/1/1-1/1/16)# switchport trunk allowed vlan 110,120,210
SW1(conf-range-eth1/1/1-1/1/16)# spanning-tree port type edge

SW1(conf-range-eth1/1/1-1/1/16)# no shutdown
SW1(conf-range-eth1/1/1-1/1/16)# show config
The output for each port appears as follows:
interface ethernet1/1/1
no shutdown
switchport mode trunk
switchport access vlan 100
switchport trunk allowed vlan 110,120,210
mtu 9216

This section describes how to configure the VLANs on the S5248F-ON switch. 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:
SW1(config)# interface vlan 100
SW1(conf-if-vl-100)# description “out-of-band VLAN”
SW1(conf-if-vl-100)# ip address 172.90.100.252/24
SW1(conf-if-vl-100)# mtu 9216
SW1(conf-if-vl-100)# vrrp-group 1
SW1(conf-if-vlan100-vrid-1)# virtual-address 172.90.100.254
SW1(conf-if-vlan100-vrid-1)# exit
SW1(conf-if-vl-100)# no shutdown
SW1(conf-if-vl-100)# exit
SW1(config)# do write
Note: You can connect iDRAC ports to the ToR switch as necessary. Use the same configuration as in this step. The configuration is the same as in the preceding steps. The Virtual Router Redundancy Protocol (VRRP) implementation is optional.

The Networking S3048-ON switch connects to the network through the Networking S5248F-ON switches using a port channel that consists of one interface on each Networking S5248F-ON switch. Follow these steps:
