Introduction 1 Introduction This document illustrates how to configure Dell EMC™ Networking S4048-ON and S4048T-ON switches for use with Dell EMC™ SC Series or Dell™ PS Series storage using Dell EMC best practices. Link aggregation groups (LAGs) for inter-switch connections are mandatory for PS Series iSCSI SAN environments and optional for SC Series iSCSI SAN environments. The switches are interconnected to each other using 40 GbE cables.
Introduction 1.4 Hardware configuration This section lists the required steps to configure your switches. The steps in this section apply to all switch OS versions. Note: Do not connect any server NIC or storage controller cables to the switch before performing the following configuration steps. 1. 2. 3. 4. Power on the two switches. Connect a serial cable to the serial port of the first switch. Using PuTTY or another terminal utility, open a serial connection session to the switch.
Introduction 1.5.1 SC Series cabling diagram The cabling diagram shown in Figure 2 represents the Dell EMC recommended method for deploying servers and SC Series storage arrays.
Introduction 1.5.2 PS Series cabling diagram The cabling diagram in Figure 2 represents the Dell EMC recommended method for deploying servers and PS Series storage arrays.
Switch command-line configuration (OS 9.x) 2 Switch command-line configuration (OS 9.x) This section provides command-line steps to configure Dell EMC Networking S4048-ON and S4048T-ON switches running Dell Networking OS 9.x. If your switches are running Dell Networking OS 10.x, skip section 2 and follow the steps in section 3. Table 2 provides an overview of the switch configuration. Switch specifications (OS 9.
Switch command-line configuration (OS 9.x) 2.1.2 Delete startup configuration Note: This example assumes a switch is using the default configuration settings. Using the delete startupconfig command will set the startup configuration file to its default settings. Always back up your configuration settings prior to performing any configuration changes. DellEMC>enable DellEMC#delete startup-config Proceed to delete startup-config [confirm yes/no]yes DellEMC#reload System configuration has been modified.
Switch command-line configuration (OS 9.x) Option 2: Enable multiple ports at once using the range parameter. DellEMC#configure DellEMC(conf)#interface range tengigabitethernet 1/1–1/48 DellEMC(conf -if-range-te-1/1-48)#switchport 2.1.7 Enable Jumbo frames DellEMC(conf -if-range-te-1/1-48)#mtu 9216 2.1.8 Configure flow control DellEMC(conf -if-range-te-1/1-48)#flowcontrol rx on tx off 2.1.
Switch command-line configuration (OS 9.x) 2.1.12 Reload switch DellEMC#reload System configuration has been modified. Save? [yes/no]:yes Proceed with reload [confirm yes/no]:yes 2.1.13 Configure additional switch Repeat the commands from section 2.1 to configure the second switch. Note: The preceding procedure places all switch ports in the default VLAN. If you prefer to place ports in a non-default VLAN, refer to the documentation for your switch. 2.
Switch command-line configuration (OS 9.x) 2.2.4 Configure DCB policies DellEMC(conf)#dcb-map DellEMC(conf-dcbmap-profile-name*)#priority-group 0 bandwidth 50 pfc off DellEMC(conf-dcbmap-profile-name*)#priority-group 1 bandwidth 50 pfc on Note: The sum of the bandwidth-percentages must be equal to 100. DellEMC(conf-dcbmap-profile-name*)#priority-pgid 0 0 0 0 1 0 0 0 DellEMC(conf-dcb-profile-name*)#exit 2.2.
Switch command-line configuration (OS 10.x) 3 Switch command-line configuration (OS 10.x) This section provides steps to configure Dell EMC Networking S4048-ON or S4048T-ON switches running Dell Networking OS 10.x. If your switches are running Dell Networking OS 9.x, do not follow the steps in section 3; follow the steps in section 2. Table 3 provides an overview of the switch configuration. Switch specifications (OS 10.
Switch command-line configuration (OS 10.x) 3.1.2 Delete startup configuration Note: This example assumes a switch is using the default configuration settings. Using the delete startupconfiguration command will set the startup configuration file to its default settings. Always back up your configuration settings prior to performing any configuration changes. OS10# delete startup-configuration Proceed to delete startup-config [confirm yes/no(default)]yes OS10# reload System configuration has been modified.
Switch command-line configuration (OS 10.x) 3.1.7 Enable Jumbo frames and flow control OS10(conf-range-eth1/1/1-1/1/48)# mtu 9216 OS10(conf-range-eth1/1/1-1/1/48)# flowcontrol receive on OS10(conf-range-eth1/1/1-1/1/48)# flowcontrol transmit off 3.1.8 Configure spanning tree on edge ports OS10(conf-range-eth1/1/1-1/1/48)# spanning-tree port type edge OS10(conf-range-eth1/1/1-1/1/48)# exit Note: Spanning tree is enabled by default. If it needs to be reconfigured, use the following command.
Switch command-line configuration (OS 10.x) 3.1.11 Configure additional switch Repeat the commands from section 3.1 to configure the second switch. Note: The preceding procedure places all switch ports in the default VLAN. If you prefer to place ports in a non-default VLAN, refer to the switch documentation. 3.2 Configure Data Center Bridging (optional) To enable Data Center Bridging (DCB) mode on the switch, use the following commands.
Switch command-line configuration (OS 10.x) 3.2.5 Create PFC dot1p traffic class The following commands configure a network QoS class map and match the iSCSI traffic class. OS10(config)# class-map type network-qos OS10 (config-cmap-nqos)# match qos-group 4 OS10 (config-cmap-nqos)# exit 3.2.
