1Introduction
This document shows how to configure Dell™Networking S5000 switches for use as a dedicated iSCSI
SAN with Dell SC Series storage using Dell best practices.
1.1 Audience
This switch configuration guide describes an optimal configuration following Dell best practices for an SC
Series iSCSI SAN and is intended for storage or network administrators and deployment personnel.
1.2 Switch details
The table below provides an overview of the switch configuration.
Table 1 Switch specifications

Switch model
S5000
Switch firmware
9.9.9.0 or later
Note: For proper functionality, the switch must be at the firmware version shown in the table above
before proceeding with this configuration. Using previous firmware versions may have unpredictable
results.

2Dell recommended switch configuration
These steps outline how to configure two S5000 switches for use as an iSCSI SAN with SC Series storage.
2.1 Hardware configuration
1. Power on the two switches.
2. Connect a serial cable to the serial port of the first switch.
3. Using any terminal utility, open a serial connection session to the switch.
4. Open the terminal emulator and configure it to use the serial port (usually COM1, but this may vary
depending on the system). Configure serial communications for 9600,N,8,1 and no flow control.
2.2 Delete startup configuration
Note: This example assumes a switch at its default configuration settings. Using the delete startup-
config command will set the startup configuration file to its default settings. You should always backup
your configuration settings prior to performing any configuration changes
FTOS>enable
FTOS#delete startup-config
Proceed to delete startup-config [confirm yes/no]yes
FTOS#reload
System configuration has been modified. Save? [yes/no]no
Proceed with reload [confirm yes/no]yes
Note: The switch will reboot.
2.3 Disabling Data Center Bridging (DCB) configuration
Note: For non-DCB environments, DCB must be manually disabled using the following steps:
FTOS>enable
FTOS#configure
FTOS(conf)#no dcb enable
FTOS(conf)#exit
FTOS#copy running-config startup-config

7 SCG2004 Dell Networking S5000 Switch Configuration Guide for SC Series SANs
2.4 Configure out of band (OOB) management port
FTOS>enable
FTOS>#config
FTOS(conf)#interface Managementethernet 0/0
FTOS(conf-if-ma-0/0)#no shutdown
FTOS(conf-if-ma-0/0)#ip address ipaddress mask
FTOS(conf-if-ma-0/0)#exit
2.5 Configure route for OOB management port (optional)
FTOS (conf)#management route X.Y.Z.0 /24 A.B.C.1
Note: X.Y.Z.0 is the network your management system is connecting from and A.B.C.1 is the gateway for
the switch. If your management system is on the same subnet as the switch, the previous step may be
omitted. The example above assumes a class C subnet mask.
2.6 Configure login credentials
FTOS(conf)#username admin password yourpassword privilege 15
FTOS(conf)#enable password yourpassword
2.7 Enable switch ports
Option 1: You can enable ports individually by entering the port number
FTOS(conf)#interface tengigabitethernet 0/0
FTOS(conf-if-te-0/0)#switchport
FTOS(conf-if-te-0/0)#no shutdown
FTOS(conf-if-te-0/0)#exit
Option 2: You can enable multiple ports at once using the “range” parameter
FTOS(conf)#interface range tengigabitethernet 0/0 –47
Note: The message below will be displayed if there are FC ports.
% Warning: Non-existing ports (non configured) are ingnored by interface-range

8 SCG2004 Dell Networking S5000 Switch Configuration Guide for SC Series SANs
FTOS(conf-if-range-te-0/0-47)#switchport
FTOS(conf-if-range-te-0/0-47)#no shutdown
2.8 Enable Jumbo Frames
FTOS(conf-if-range-te-0/0-47)#mtu 12000
2.9 Enable flow control
FTOS(conf-if-range-te-0/0-47)#flowcontrol rx on tx off
2.10 Configure spanning tree on edge ports
Note: Use the following command only on server- and storage-connected edge ports.
FTOS(conf-if-range-te-0/0-47)#spanning-tree rstp edge-port
FTOS(conf-if-range-te-0/0-47)#exit
FTOS(conf)#protocol spanning-tree rstp
FTOS(conf-rstp)#no disable
FTOS(conf-rstp)#exit
2.11 Configure VLAN
Note: Dell recommends assigning a unique vlan_id (between 2-4094) for each switch fabric. For
example, assign VLAN 100 on the first switch and VLAN 200 on the second switch. The following
example assigns all the ports to the VLAN, however, you may also assign individual ports to the VLAN
after they are enabled (Section 2.7). If you prefer to use the default VLAN, then you may skip this section
entirely.
FTOS(config)#interface vlan vlan_id
FTOS#(config-if-vl-###)#no shutdown
FTOS#(config-if-vl-###)#untagged tengigabitethernet 0/0-47
FTOS#exit

2.12 Save configuration
FTOS#copy running-config startup-config
2.13 Configure additional switch
Repeat the commands from Section 2 to configure the second switch.

3Configure UPM ports as Ethernet pass-through (optional)
The FC ports on the Unified Port Module (UPM) can be configured as Ethernet pass-through. Use this
section only if the UPM module is used. The 12 ports are divided into six port groups numbered 0-5. Two
ports in each port group can be configured separately as FC or Ethernet pass-through.
Note: This operation requires a reload for the changes to take effect.
3.1 View the current configuration
Use this command to view the current mode of the ports and also the port group mapping.
FTOS# show system stack-unit 0 port-group portmode
PortGroupId Ports Mode(Curr Boot) Mode(Next Boot)
0 0,1 FC FC
1 2,3 FC FC
2 4,5 FC FC
3 6,7 FC FC
4 8,9 FC FC
5 10,11 FC FC
3.2 Configure port group 0 as Ethernet pass-through
FTOS(conf)# stack-unit 0 port-group 0 portmode Ethernet
Changing port mode on slot 0 port-group 0 will make interface configs of 0 and 1
obsolete after a save and reload.
[confirm yes/no]:yes
Please save and reload for the changes to take effect.
Note: Save and reload is required.

11 SCG2004 Dell Networking S5000 Switch Configuration Guide for SC Series SANs
3.3 To revert Ethernet pass-through to FC ports
FTOS(conf)# no stack-unit 0 port-group 0 portmode ethernet
Changing port mode on slot 0 port-group 0 will make interface configs of 0 and 1
obsolete after a save and reload.
[confirm yes/no]:yes
Please save and reload for the changes to take effect.
Note: Save and reload is required.
