1Introduction

This document illustrates how to configure a Cisco® Nexus 9504 chassis for use with Dell™ SC Series

storage using Dell best practices. The recommended configuration when using a single chassis is to

configure two I/O modules.

For more information on SC Series SAN design recommendations, see the

Dell Storage Compatibility

Matrix

1.1 Audience

This switch configuration guide describes a verified configuration following Dell best practices for a

dedicated 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

Nexus 9504

Switch firmware

7.0(3)I1(2)

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 show you how to configure a single Cisco Nexus 9504 chassis with two linecard modules that

are installed in Slot 1 and Slot 2.

Note: The configuration steps in this section are only recommended when the switch is used as a

dedicated SAN for iSCSI traffic (not shared with LAN traffic).

2.1 Hardware configuration

1. Power on the chassis

2. Connect a serial cable to the active supervisor management port.

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.

2.2 Delete startup configuration

Note: This example assumes a switch at its default configuration settings. Using the “write erase”

command will set the startup configuration file to its default settings. You should always backup your

configuration settings prior to performing any configuration changes

switch#write erase

Warning: This command will erase the startup-configuration

Do you wish to proceed anyway ? (y/n) [n] y

switch# reload

This command will reboot the system

Do you want to continue? (y/n) [n] y

Note: The switch will reboot.

7 SCG3252 | Cisco Nexus 9504 Switch Configuration Guide for Dell SC Series SANs

2.3 Running the basic system configuration

The following steps use the setup utility to configure connectivity for basic management of the system.

After the switch fully reboots, the following prompts will appear:

Abort Power On Auto Provisioning and continue with normal setup ?(yes/no)[n]: y

---- System Admin Account Setup ----

Do you want to enforce secure password standard (yes/no): yes

Enter the password for "admin": my password

Confirm the password for "admin": my password

---- Basic System Configuration Dialog VDC: 1 ----

This setup utility will guide you through the basic configuration of

the system. Setup configures only enough connectivity for management

of the system.

Please register Cisco Nexus9000 Family devices promptly with your

supplier. Failure to register may affect response times for initial

service calls. Nexus9000 devices must be registered to receive

entitled support services.

Press Enter at anytime to skip a dialog. Use ctrl-c at anytime

to skip the remaining dialogs.

Would you like to enter the basic configuration dialog (yes/no): yes

Create another login account (yes/no) [n]: n

Configure read-only SNMP community string (yes/no) [n]: n

Configure read-write SNMP community string (yes/no) [n]: n

Enter the switch name : my switch name

Continue with Out-of-band (mgmt0) management configuration? (yes/no) [y]: y

Mgmt0 IPv4 address : my IP address

Mgmt0 IPv4 netmask : my netmask

Configure the default gateway? (yes/no) [y]: y

IPv4 address of the default gateway : my gateway

Configure advanced IP options? (yes/no) [n]:n

Enable the telnet service? (yes/no) [n]: y

Enable the ssh service? (yes/no) [y]: n

Configure the ntp server? (yes/no) [n]: n

Configure default interface layer (L3/L2) [L2]: L2

Configure default switchport interface state (shut/noshut) [shut]: shut

Configure CoPP system profile (strict/moderate/lenient/dense/skip) [strict]:skip

The following configuration will be applied:

Would you like to edit the configuration? (yes/no) [n]: n

Use this configuration and save it? (yes/no) [y]: y

[########################################] 100%

Copy complete.

Log into the switch using the credentials you created.

Note: You must perform port configurations for each individual port that is connected to a storage

controller or a host server interface port, or you can specify a range of ports to configure. This example

assumes all 48 ports on Linecard Modules 1 and 2.

2.4 Enabling Jumbo Frames

switch# configure

switch(config)#system jumbomtu 9216

switch(config)# interface ethernet 1/1-48 , ethernet 2/1-48

switch(config-if-range)# mtu 9216

switch(config-if-range)#exit

Note: By default, Data Center Bridging (DCB) is enabled. This document will provide steps to disable

DCB. Perform all operations during a maintenance window, whereas a temporary loss of

communication between host servers and storage arrays may occur.

2.5 Enabling LLDP

switch(config)#feature lldp

switch(config)#interface ethernet 1/1-48 , ethernet 2/1-48

switch(config-if-range)# lldp receive

switch(config-if-range)# lldp transmit

switch(config-if-range)#exit

switch(config)#exit

9 SCG3252 | Cisco Nexus 9504 Switch Configuration Guide for Dell SC Series SANs

2.6 Disabling Data Center Bridging (DCB)

All steps in Section 2.6 are required in order to properly disable DCB. Also, when upgrading from previous

versions to version 7.0(3)I1(2), Section 2.6 must be performed to properly disable DCB.

switch# configure

switch(config)#lldp tlv-select dcbxp

switch(config)#copy running-config startup-config

switch(config)#no lldp tlv-select dcbxp

switch(config)#exit

switch#copy running-config startup-config

Note: The above steps are needed due to Cisco Bug Number “CSCuo63486 LLDP - link err-disabled

upon reload when dcbx tlv is disabled”.

2.7 Enable link level flow control (802.3x)

You must perform this step for each individual port that is connected to a storage controller or a host

server interface port, or you can specify a range of ports to configure.

switch# configure

switch(config)#interface ethernet 1/1-48 , ethernet 2/1-48

switch(config-if-range)#priority-flow-control mode off

switch(config-if-range)#flowcontrol send off

switch(config-if-range)#flowcontrol receive on

switch(config-if-range)#exit

2.8 Configure portfast on edge ports

switch(config)#interface ethernet 1/1-48 , ethernet 2/1-48

switch(config-if-range)#spanning-tree port type edge

Warning: edge port type (portfast) should only be enabled on ports connected to

a single host. Connecting hubs, concentrators, switches, bridges, etc… to this

interface when edge port type (portfast) is enabled, can cause temporary

bridging loops. Use with CAUTION.

Edge Port Type (Portfast) will be configured in 96 interfaces due to the range

commend but will only have effect when the interfaces are in a non-trunking

mode.

switch(config-if-range)#exit

10 SCG3252 | Cisco Nexus 9504 Switch Configuration Guide for Dell SC Series SANs

2.9 Enable switch ports

The following example enables a range of ports. If preferred, you may enable individual ports as needed.

switch(config)# interface ethernet 1/1-48 , ethernet 2/1-48

switch(config-if-range)# shutdown

switch(config-if-range)# no shutdown

switch (config-if-range)# exit

2.10 Save configuration

switch#copy running-config startup-config

switch#reload
