Introduction
This guide provides general configuration examples. The configurations found here may not be applicable for all
environments. Consult Lenovo’s official documentation for further information in regards to your environment's
unique configuration.
Requirements
●This guide was written for CNOS version 10.8.1.0. If you are on a lesser version, update to match 10.8.1.0
due to command syntax changes.
●A Terminal Emulation program, such as PuTTY.
●(Optional) Mini-USB B male to USB A male cable.

Connect to the Switch
Over the Network
By default, the management interface is set to request a DHCP address. If DHCP is available, check your leases on
your DHCP server to determine the IP address of the switch. Using an SSH client, you may log in to the switch over
the network. The default username is admin, and the default password is admin.
Console
Using a terminal emulator, such as PuTTY, connect the provided USB adapter to the port shown below.
Set your console settings as follows:
Default baud rate = 9,600 bps
Character size = 8 characters
Parity = none
Stop bits = 1
Data bits = 8
Flow control = none
The default username is admin and the default password is admin.

CLI Mode Basics
Configuration for the NE1032 is performed through a CLI interface. As a reference:
> = unprivileged mode
# = privileged mode
(config)# = global configuration mode
(config-if)# = interface configuration mode
(config-vrf)# = virtual routing and forwarding configuration mode
Upon login you will be in the unprivileged mode. To enter privileged mode:
> enable
#
NOTE
You can use ? to display what commands are available in the current mode.
In order to configure the switch we need to enter global configuration mode. This mode is used for settings that
aren’t specific to the switch ports.
# conf t
(config)#
Configuration of switch ports is performed in interface configuration mode. To return to the previous configuration
level:
(config-if)# exit
(config)#

Set the Management IP
The management network should be separated from any data networks and have physically independent hardware
supporting it. The goal of the management network is to maintain remote access to network equipment should a
configuration change interrupt the data networks. Optionally, you may use a VLAN interface instead.
Management Configuration Example
> en
# conf t
(config)# int mgmt0
(config)# ip addr 10.205.13.252 255.255.255.0
(config)# vrf context management
(config-vrf)# ip route 0.0.0.0/0 10.205.13.1
Management VLAN Configuration Example
> en
# conf t
(config)# interface vlan 1
(config-if)# ip address 10.205.13.252 255.255.255.0
(config-if)# exit
(config)# ip route 0.0.0.0/0 10.205.13.1

Update the Firmware
Download the Latest Firmware
Download the zip file here.
Unzip the archive. Rename the extracted folder to ne1032 and place it in your local user home directory. Make sure
your firewall will allow port 22, or turn it off temporarily. If you are using a linux machine, ensure sshd is running.
# copy sftp sftp://10.205.105.202//home/cdraper/ne1032/NE1032-CNOS-10.8.1.0.imgs system-

Boot image installation succeeded.
OS image installation succeeded.
Boot loader now contains Software Version 10.8.1.0
Standby image now contains Software Version 10.8.1.0
Switch is currently set to boot active image.
Do you want to change that to the standby image? (y/n) [n] y
Reboot the switch to load the new firmware:
# reload

General Configuration
Set the Enable Mode Password
(config)# enable password SOMEPASS
Generate New SSH keys
# conf t
(config)# no feature ssh
(config)# ssh key rsa length 4096 force
(config)# ssh login-attempts 3
(config)# feature ssh
Set AAA Maximum Attempts
Authentication, authorization, and accounting features determine what resources users have access to, and where to
check for that user’s credentials. Here, we are setting failed login attempts to be logged and the maximum number of
login attempts to 25.
(config)# aaa authentication login error-enable
(config)# aaa local authentication attempts max-fail 25
Create Additional Users
The network-admin account type has full administrative rights to the switch. The network-operator is a limited
account type.
(config)# username <ADMIN> role network-admin password <PASSWORD>
(config)# username <USER> role network-operator password <PASSWORD>
Set NTP
Any internal or external NTP server that is accessible on your network should work.
(config)# feature ntp
(config)# ntp server 10.205.13.2
© Scale Computing 2018 9
Set DNS
Any internal DNS server that is accessible on your network should work.
(config)# ip name-server 10.205.13.3 vrf default
Create VLANs
You may create VLANs individually as follows:
(config)# vlan 2
(config-vlan)# name SCALEBACKPLANE
Or, you may create multiple VLANs at once using a range:
(config)# vlan 1-10
Verify Spanning Tree
(config)# sh spanning-tree
Ensure that the spanning tree protocol supports rapid convergence. By default the NE1032 uses rapid-pvst.
VLAN0001
spanning-tree enabled protocol rapid-pvst
