Configuring Dell EMC Networking S5248F-ON switches

  • 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.

    1. 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
    1. When the connection is successful, enter configuration mode by running the following command:

    OS10# configure terminal

    1. 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>

    1. 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

    1. 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

    1. 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

    1. 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

    1. 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

    1. 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.

    1. 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

    1. 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

    1. 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

    1. 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

    1. 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

    1. 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

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