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 switchesProcedure

Configure the S5248F-ON switches:

1. Using the RJ45 serial cable included with your switch, connect one end to your workstation and the other end to the RS-232 console port of the switch.

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.

Figure 3.        Serial port

2. Using terminal emulation software, configure the appropriate COM port as follows:

• 15200 baud rate
• No parity/no flow control
• 8 data bits/1 stop bit

3. When the connection is successful, enter configuration mode by running the following command:

OS10# configure terminal

4. Configure the hostname and time zone and set a username and password for EXEC mode by running the following commands:

OS10(config)# hostname <hostname>

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

SW1(config)# clock timezone <time zone, for example, CST -6 0>

5. Configure routing to your default gateway, and save the configuration by running the following commands:

SW1(config)# ip route 0.0.0.0/0 <core network gateway>

SW1(config)# do write memory

Configure the management interface

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:

1. Configure the management port by running the following commands:

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

2. Enable SPT by running the following commands:

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 VLTi

Configure the ports to be used for VLTi traffic:

1. Run the following commands:

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

2. Create the VLT domain and add the discovery interfaces:

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

3. Ensure that the VLT domain is properly configured by running the following command in enable mode:

SW1# show vlt 1 | find Status

The following output appears:

VLTi Link Status

    port-channel1000       : up

VLT Peer

Unit ID  System MAC Address  Status  IP Address    Version

-----------------------------------------------------------------  1        54:bf:64:be:f7:40   up      192.168.1.253  2.0

4. Run the following commands to configure the ports that the servers are connected to on the switch. Based on the site survey example, ports Ethernet 1/1/1 through Ethernet 1/1/16 are in use on each switch.

SW1(config)# interface range ethernet 1/1/1-1/1/16

SW1(conf-range-eth1/1/1-1/1/16)# no ip address

SW1(conf-range-eth1/1/1-1/1/16)# mtu 9216

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)# spanning-tree guard root

SW1(conf-range-eth1/1/1-1/1/16)# no shutdown

5. Verify that the ports are properly configured by running the following command:

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

 flowcontrol receive off

 spanning-tree guard root

 spanning-tree port type edge

Configure the VLANs

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:

1. Configure the OOB VLAN:

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.

2. Configure the management VLAN by running the following commands:

SW1(config)# interface vlan 110

SW1(conf-if-vl-110)# description “Management VLAN”

SW1(conf-if-vl-110)# ip address 172.90.110.252/24

SW1(conf-if-vl-110)# mtu 9216

SW1(conf-if-vl-110)# vrrp-group 2

SW1(conf-if-vlan110-vrid-2)# virtual-address 172.90.110.254

SW1(conf-if-vlan110-vrid-2)# exit

SW1(conf-if-vl-110)# no shutdown

SW1(conf-if-vl-110)# exit

SW1(config)# do write

3. Configure the live migration VLAN by running the following commands:

SW1(config)# interface vlan 120

SW1(conf-if-vl-120)# description “Live Migration VLAN”

SW1(conf-if-vl-120)# ip address 172.90.120.252/24

SW1(conf-if-vl-120)# mtu 9216

SW1(conf-if-vl-120)# vrrp-group 3

SW1(conf-if-vlan120-vrid-3)# virtual-address 172.90.120.254

SW1(conf-if-vlan120-vrid-3)# exit

SW1(conf-if-vl-120)# no shutdown

SW1(conf-if-vl-120)# exit

SW1(config)# do write

4. Configure the compute VM VLAN by running the following commands:

SW1(config)# interface vlan 210

SW1(conf-if-vl-210)# description “Compute VM VLAN”

SW1(conf-if-vl-210)# ip address 172.90.210.252/24

SW1(conf-if-vl-210)# mtu 9216

SW1(conf-if-vl-210)# vrrp-group 4

SW1(conf-if-vlan210-vrid-3)# virtual-address 172.90.210.254

SW1(conf-if-vlan210-vrid-3)# exit

SW1(conf-if-vl-210)# no shutdown

SW1(conf-if-vl-210)# exit

SW1(config)# do write

5. To verify that all the settings have been properly recorded, review the configuration from enable mode by running the following command:

SW1# show running-config

6. Repeat the preceding steps to configure the bottom Dell EMC Networking S5248F-ON switch in the configuration.

Configure the port channel

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:

1. Configure the port-channel that will be used by running these commands:

SW1(config)# interface port-channel 101

SW1(conf-if-po-101)# description “OOB uplink”

SW1(conf-if-po-101)# no shutdown

SW1(conf-if-po-101)# switchport mode trunk

SW1(conf-if-po-101)# switchport trunk allowed vlan 100,110,120,210

SW1(conf-if-po-101)# mtu 9216

SW1(conf-if-po-101)# vlt-port-channel 101

SW1(conf-if-po-101)# exit

2. Configure the port that will be used for the port channel by running these commands:

SW1(config)# port-group 1/1/12

SW1(conf-pg-1/1/12)# mode Eth 10g-4x

SW1(conf-pg-1/1/12)# exit

SW1(config)# interface ethernet 1/1/48:1

SW1(conf-if-eth1/1/48:1)# no shutdown

SW1(conf-if-eth1/1/48:1)# description “OOB uplink”

SW1(conf-if-eth1/1/48:1)# channel-group 101 mode active

SW1(conf-if-eth1/1/48:1)# mtu 9216

SW1(conf-if-eth1/1/48:1)# exit

3. Repeat the preceding steps to configure the bottom Dell EMC Networking S5248F-ON switch.
