1Introduction
This document illustrates how to configure Dell™ Networking S4810 and Dell Force10™S4810 switches
for use with EqualLogic™PS Series storage using Dell best practices. The recommended configuration
uses link aggregation groups (LAGs) for inter-switch connections. Optional steps are provided in Section 3
to enable Data Center Bridging (DCB) and for stack configurations.
If you are following the Rapid EqualLogic Configuration steps at
http://en.community.dell.com/techcenter/storage/w/wiki/3615.rapid-equallogic-configuration-portal-
by-sis.aspx, use sections 1 and 2, or 1 and 5 in this Switch Configuration Guide.
For more information on EqualLogic SAN design recommendations, see the EqualLogic Configuration
Guide at: www.delltechcenter.com/page/equallogic+configuration+guide.
1.1 Audience

2Dell recommended switch configuration
These steps show you how to configure two S4810 switches with a Link Aggregation Group (LAG). The
switches are interconnected using two of the 40 GbE Quad Small Form-factor Pluggable (QSFP) uplink
ports, and the LAG is configured for Dynamic Link Aggregation Control Protocol (LACP).
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 Putty or another terminal utility, open a serial connection session to the switch.
4. Open your terminal emulator and configure it to use the serial port (usually COM1 but this may
vary depending on your system). Configure serial communications for 9600,N,8,1 and no flow
control.
5. Connect the (QSFP) LAG cables between the switches, by connecting port 48 on switch 1 to port
48 on switch2 and port 52 on switch 1 to port 52 on switch 2. See this configuration in Figure 1.
2.2 Delete startup configuration
Note: The following commands will delete all configuration settings.
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 Configure out of band (OOB) management port
FTOS>enable
After the startup configuration is deleted, the factory default Enable mode password is force10.
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

8 SCG1000 | Dell Networking S4810 and Force10 S4810 Configuration Guide for EqualLogic SANs
2.4 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.
2.5 Configure login credentials
FTOS(conf)#username admin privilege 15 password 0 yourpassword
FTOS(conf)#enable password level 15 0 yourpassword
2.6 Enable switch ports
Option 1: You can enable ports individually by entering the port number.
FTOS#configure
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
FTOS(conf)#exit
Option 2: You can enable multiple ports at once using the ‘range’ parameter.
FTOS#configure
FTOS(conf)#interface range tengigabitethernet 0/0 –47
FTOS(conf -if-range-te-0/0-47)#switchport
FTOS(conf -if-range-te-0/0-47)#no shutdown
FTOS(conf -if-range-te-0/0-47)#exit
FTOS(conf)#exit
2.7 Enable Jumbo Frames
FTOS#configure
FTOS(conf)# interface range tengigabitethernet 0/0 –47
FTOS(conf -if-range-te-0/0-47)#mtu 12000
2.8 Configure flow control
FTOS(conf -if-range-te-0/0-47)#flowcontrol rx on tx off

FTOS(conf-if-range-te-0/0-47)#exit
FTOS(conf)#protocol spanning-tree rstp
FTOS(conf-rstp)#no disable
FTOS(conf-rstp)#exit
2.10 Configure port channel for LAG
These commands configure the switch interconnect as a LAG.
FTOS(conf)#interface Port-channel 1
FTOS(conf-if-po-1)#mtu 12000
FTOS(conf-if-po-1)#switchport
FTOS(conf-if-po-1)#no shutdown
FTOS(conf-if-po-1)#exit
2.11 Configure QSFP ports for LAG
These commands assigns 40Gb QSFP ports to the Port Channel.
FTOS(conf)#interface range fortyGigE 0/48 , fortyGigE 0/52
FTOS(conf-if-range-fo-0/48,fo-0/52)#no ip address
FTOS(conf-if-range-fo-0/48,fo-0/52)#mtu 12000
FTOS(conf-if-range-te-0/48,fo-0/52)#no shutdown
FTOS(conf-if-range-fo-0/48,fo-0/52)#flowcontrol rx on tx off
FTOS(conf-if-range-fo-0/48,fo-0/52)#port-channel-protocol lacp
FTOS(conf-if-range-fo-0/48,fo-0/52-lacp)#port-channel 1 mode active
FTOS(conf-if-range-fo-0/48,fo-0/52-lacp)#exit
FTOS(conf-if-range-fo-0/48,fo-0/52)#exit
FTOS(conf)#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.
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.

10 SCG1000 | Dell Networking S4810 and Force10 S4810 Configuration Guide for EqualLogic SANs
3Configure Data Center Bridging (DCB) (Optional)
To enable DCB mode on the switch, use the following commands.
Note: You must complete the Dell recommended switch configuration steps in Sections 2.1 to 2.12
before configuring the switch for DCB mode.
3.1 Disable 802.3x flowcontrol on SFP+ ports
FTOS#configure
FTOS(conf)#interface range tengigabitethernet 0/0 - 47
FTOS(conf-if-range-te-0/0-47)#no flowcontrol rx on tx off
FTOS(conf-if-range-te-0/0-47)#exit
3.2 Disable 802.3x flowcontrol on QSFP ports
FTOS(conf)# interface range fortyGigE 0/48 , fortyGigE 0/52
FTOS(conf-if-range-fo-0/48-52)#no flowcontrol rx on tx off
FTOS(conf-if-range-fo-0/48-52)#exit
3.3 Enable DCB and reload
FTOS(conf)#dcb enable
FTOS(conf)#exit
FTOS#copy running-config startup-config
FTOS#reload
Note: The switch will reboot.
3.4 Create tagged VLAN for all ports and port-channels
FTOS#configure
FTOS(conf)#interface vlan vlan-id
Note: You must supply a VLAN id. The valid range is 2-4093.
FTOS (conf-if-vl-vlan-id*)#no shutdown
FTOS (conf-if-vl-vlan-id*)#tagged tengigabitethernet 0/0-47
FTOS (conf-if-vl-vlan-id*)#tagged port-channel 1
FTOS (conf-if-vl-vlan-id*)#exit

11 SCG1000 | Dell Networking S4810 and Force10 S4810 Configuration Guide for EqualLogic SANs
3.5 Configure DCB policies
FTOS(conf)#dcb-map profile-name
FTOS(conf-dcbmap-profile-name*)#priority-group 0 bandwidth 50 pfc off
FTOS(conf-dcbmap-profile-name*)#priority-group 1 bandwidth 50 pfc on
Note: The sum of the bandwidth-percentages must be equal to 100.
FTOS(conf-dcbmap-profile-name*)#priority-pgid 0 0 0 0 1 0 0 0
FTOS(conf-dcb-profile-name*)#exit
3.6 Apply policies to switch ports
FTOS(conf)#interface range ten 0/0 –47
FTOS(conf-if-range-te-0/0-47)# dcb-map profile-name
FTOS(conf-if-range-te-0/0-47)#exit
FTOS(conf)#interface range fortyGigE 0/48 , fortyGigE 0/52
FTOS(conf-if-range-fo-0/48,fo-0/52)# dcb-map profile-name
FTOS(conf-if-range-fo-0/48,fo-0/52)#exit
FTOS(conf)#exit
Note: The sum of the bandwidth-percentages must be equal to 100.
3.7 Save configuration
FTOS#copy running-config startup-config
3.8 Configure additional switches
Repeat the commands from section 3 to configure DCB on additional switches.

12 SCG1000 | Dell Networking S4810 and Force10 S4810 Configuration Guide for EqualLogic SANs
4Reverting from DCB to non-DCB configuration (Optional)
One method to revert from a DCB configured switch to a non-DCB configured switch is to delete the
current configuration (startup-config) and follow the steps in Section 2. If deleting the current
configuration is not an option, then use the following procedure to unconfigure DCB and enable standard
flow control.
Note: This is a disruptive operation that requires down time. The arrays will temporarily lose
communication with each other. Power off all arrays and hosts connected to the SAN before proceeding
with these steps.
4.1 Disable DCB
FTOS#configure
FTOS(conf)#no dcb enable
FTOS(conf)#exit
4.2 Remove DCB policies and apply standard flow control
FTOS#configure
FTOS(conf)#interface range tengigabitethernet 0/0 - 47
FTOS(conf-if-range-te-0/0-47)#no dcb-map profile-name
FTOS(conf-if-range-te-0/0-47)#flowcontrol rx on tx off
FTOS(conf-if-range-te-0/0-47)#exit
FTOS(conf)#interface range fortyGigE 0/48 , fortyGigE 0/52
FTOS(conf-if-range-fo-0/48,fo-0/52)#no dcb-map profile-name
FTOS(conf-if-range-fo-0/48,fo-0/52)#flowcontrol rx on tx off
FTOS(conf-if-range-fo-0/48,fo-0/52)#exit
FTOS(conf)#exit
4.3 Revert to default VLAN ID on switch and arrays
Once DCB is disabled on the switch, the EqualLogic arrays will no longer use the VLAN ID that was
configured when DCB was enabled. The arrays will revert to the default or native VLAN. Therefore, a valid
VLAN must be configured for all host servers, switches, and EqualLogic array members. A valid VLAN can
use the default or native VLAN ID (typically 0 or 1) or a specific VLAN can be configured (for example,
VLAN 100). If a non-default VLAN is configured, then any ports connected to the arrays must be
configured as “untagged”.
Note: Host NICS must also be updated with matching VLAN information.
Use the steps below to configure the native VLAN on the switch.

13 SCG1000 | Dell Networking S4810 and Force10 S4810 Configuration Guide for EqualLogic SANs
FTOS#configure
FTOS(conf)#no interface vlan vlan-id
4.4 Save configuration
FTOS#copy running-config startup-config
4.5 Reload
FTOS#reload
System configuration has been modified. Save? [yes/no]yes
Proceed with reload [confirm yes/no]yes
Note: The switch will reboot.
4.6 Verify DCB status
FTOS#show dcb
Figure 2 Screen shot of show DCB
4.7 Configure additional switch
Repeat the commands from section 4 to disable DCB on any additional switches.

14 SCG1000 | Dell Networking S4810 and Force10 S4810 Configuration Guide for EqualLogic SANs
5Optional stack configuration
Note: If you wish to use a stack configuration instead of LAG, follow the instructions below instead of
Section 2.
One advantage of stacked switches is that they can be managed as a single switch; however firmware
updates will update all members of the stack simultaneously and therefore should only be done during
planned downtime.
5.1 Delete startup configuration on first switch
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.
5.2 Configure stack on the first switch
FTOS>enable
After the startup configuration is deleted, the factory default Enable mode password is force10.
FTOS#config
FTOS(conf)#stack-unit 0 priority 1
FTOS(conf)#stack-unit 0 stack-group 12
FTOS(conf)#stack-unit 0 stack-group 13
FTOS(conf)#exit
FTOS#copy running-config startup-config
FTOS#reload
5.3 Delete startup configuration on the second switch
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

15 SCG1000 | Dell Networking S4810 and Force10 S4810 Configuration Guide for EqualLogic SANs
Note: The switch will reboot.
5.4 Configure stack on the second switch
FTOS>enable
FTOS#stack-unit 0 renumber 1
Note: The switch will reboot.
FTOS#config
FTOS(conf)#stack-unit 1 priority 1
FTOS(conf)#stack-unit 1 stack-group 12
FTOS(conf)#stack-unit 1 stack-group 13
FTOS(conf)#exit
FTOS#copy running-config startup-config
FTOS#reload
5.5 Verify stack configuration
From the first switch (Master) CLI, confirm that the stack has formed:
FTOS#show redundancy
Note: The switch front panel will show a steady light in the MASTER LED for the Master unit and a
blinking light for the Standby unit. All of the following configuration step must be performed from the
master switch.
5.6 Configure out of band (OOB) management port
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)#no shutdown
FTOS(conf-if-ma-0/0)#exit
5.7 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.

5.8 Configure login credentials
FTOS(conf)#username admin privilege 15 password 0 yourpassword
FTOS(conf)#enable password level 15 0 yourpassword
5.9 Configuring switch ports
FTOS(conf)#interface range tengigabitethernet 0/0 –47
FTOS(conf-if-range-te-0/0-47)#mtu 12000
FTOS(conf-if-range-te-0/0-47)#switchport
FTOS(conf-if-range-te-0/0-47)#spanning-tree rstp edge-port
FTOS(conf-if-range-te-0/0-47)#flowcontrol rx on tx off
FTOS(conf-if-range-te-0/0-47)#no shutdown
FTOS(conf-if-range-te-0/0-47)#exit
FTOS(conf)#interface range tengigabitethernet 1/0 –47
FTOS(conf-if-range-te-1/0-47)#mtu 12000
FTOS(conf-if-range-te-1/0-47)#switchport
FTOS(conf-if-range-te-1/0-47)#spanning-tree rstp edge-port
FTOS(conf-if-range-te-1/0-47)#flowcontrol rx on tx off
FTOS(conf-if-range-te-1/0-47)#no shut
FTOS(conf-if-range-te-1/0-47)#exit
FTOS(conf)#protocol spanning-tree rstp
FTOS(conf-rstp)#no disable
FTOS(conf-rstp)#exit
FTOS(conf)#exit
5.10 Save configuration and reload
FTOS#copy running-config startup-config
Reload the stack to allow settings to take effect:
FTOS#reload
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.
