Getting Started 19

Download OS10 image and license

OS10 Enterprise Edition may come factory-loaded and is available for download from the Dell Digital Locker (DDL). A factory-loaded OS10 image has a perpetual license installed. An OS10 image that you download has a 120-day trial license and requires a perpetual license to run beyond the trial period. See the Quick Start Guide shipped with your device and My Account FAQs for more information.
Download an OS10 image and license to:
• Re-install the license on a Dell EMC ONIE switch with factory-installed OS10 image and license.
• Install OS10 on a Dell EMC ONIE switch without an operating system (OS) or license installed:
• Device converted from OS9 or a third-party OS after you uninstall (wipe clean) the original OS
• Replacement device received from Dell EMC return material authorization (RMA)
• Upgrade the OS10 image (see Upgrade OS10).
Your OS10 purchase allows you to download software images posted within the rst 90 days of ownership. To extend the software entitlement, you must have a Dell EMC ProSupport or ProSupport Plus contract on your hardware.
Re-install license on factory-loaded OS10
OS10 Enterprise Edition runs with a perpetual license on an ONIE-enabled device with OS10 factory-installed. The license le is installed on the switch. If the license becomes corrupted or is wiped out, you must download the license from DDL under the purchaser's account and reinstall it.
1 Sign in to DDL using your account credentials. 2 Locate the hardware product name with the entitlement ID and order number. 3 Check that the service tag of the purchased device displays in the Assigned To: eld on the Products page.
4 Click Key Available for Download.
5 Select how you want to receive the license key — by email or downloaded to your local device. 6 Click Submit.
7 Save the License.zip le and follow the instructions in Install license to install the license.
Without operating system installed
You can purchase the OS10 Enterprise Edition image with an after point-of-sale (APOS) order for a Dell EMC ONIE-enabled device that does not have a default operating system or license installed. When the order is fullled, you receive an email notication with a software entitlement ID, order number, and link to the DDL.
Bind the software entitlement to the service tag of the switch to extend the entitled download period to be the same time as the support contract. OS10 software entitlement allows you to download OS10 software images posted before the purchase date and within 90 days of the date, by default.
1 Sign into DDL using your account credentials. 2 Locate the entry for your entitlement ID and order number sent by email, then select the product name. 3 On the Productpage, the Assigned To: eld on the Product tab is blank. Click Key Available for Download.
4 Enter the service tag of the device you purchased the OS10 Enterprise Edition for in the Bind to: and Re-enter ID: elds. This
step binds the software entitlement to the service tag of the switch. 5 Select how you want to receive the license key — by email or downloaded to your local device. 6 Click Submit to download the License.zip le.
7 Select the Available Downloads tab.
8 Select the OS10 Enterprise Edition release to download, then click Download.
9 Read the Dell End User License Agreement. Scroll to the end of the agreement, then click Yes, I agree.
10 Select how you want to download the software les, then click Download Now.
20
Getting Started
Once you download the OS10 Enterprise Edition image, unzip the .tar le. Some Windows unzip applications insert extra carriage returns (CR) or line feeds (LF) when they extract the contents of a .tar le, which may corrupt the downloaded OS10 binary image. Turn o this option if you use a Windows-based tool to untar an OS10 binary le.
Once you unzip the OS10 Enterprise Edition and download the license, see Installation and Install license for complete installation and license information.
RMA replacement
A replacement switch comes without an operation system or license installed. If you receive a replacement switch, you must assign the STAG of the replacement switch to the SW entitlement in DDL and install the OS10 software and license.
Follow the steps for an ONIE switch without an OS installed to download OS10 Enterprise Edition and the license. See Installation and
Install license for complete installation and license information.

Installation

You can install OS10 using an industry-standard open network install environment (ONIE) software image with auto-discovery or using a manual installation:
• Automatic (zero-touch) installation — ONIE discovers network information including the DHCP server, connects to an image server,
options to point to the server for the image, and downloads and installs an image automatically.
• Manual installation — Manually congure your network information if a DHCP server is not available, or if you install the OS10
software image using USB media.
System setup
Verify that the system is connected correctly before installation:
• Connect a serial cable and terminal emulator to the console serial port — required serial port settings are 115200, 8 data bits, and no
parity.
• Connect the Management port to the network if you prefer downloading an image over a network. To locate the Console port and the
Management port, see the Getting Started Guide shipped with your device or the platform-specic Installation Guide at
www.dell.com/support.
Install OS10
If an operating system (OS) is installed on a device, navigate to the ONIE boot menu. An ONIE-enabled device boots up with pre-loaded diagnostics and ONIE software.
+--------------------------------------------------------+ |*ONIE: Install OS | | ONIE: Rescue | | ONIE: Uninstall OS | | ONIE: Update ONIE | | ONIE: Embed ONIE | | ONIE: Diag ONIE | +--------------------------------------------------------+
• Install OS — Boots to the ONIE prompt and installs an OS10 image using the automatic discovery process.
• Rescue — Boots to the ONIE prompt and allows for manual installation of an OS10 image or updating ONIE.
• Uninstall OS — Deletes the contents of all disk partitions except ONIE and diagnostics.
• Update ONIE — Installs a new ONIE version.
• Embed ONIE — Formats an empty disk and installs ONIE.
• Diag ONIE — Runs the system diagnostics.
CAUTION
installation, perform Uninstall OS rst to clear the partitions if there is an existing OS on the device. If the problem persists, contact Dell EMC Technical Support.

Getting Started 21

Automatic installation

You can automatically (zero-touch) install an OS10 image on a Dell ONIE-enabled device. Once the device successfully boots to ONIE: Install OS, auto-discovery obtains the hostname, domain name, Management interface IP address, as well as the IP address of the DNS name server(s) on your network from the DHCP server and DHCP options. The ONIE automatic-discovery process locates the stored software image, starts installation, then reboots the device with the new software image.
If a USB drive is inserted, auto-discovery searches the USB storage supporting FAT or EXT2 le systems. It also searches SCP, FTP, or TFTP servers with the default DNS name of the ONIE server. DHCP options are not used to provide the server IP, and the auto discovery method repeats until a successful software image installation occurs and reboots the switch.

Manual installation

You can manually install an OS10 software image if a DHCP server is not available. If the IP address for the Management port (eth0) is not automatically discovered, ONIE sets the IP address to 192.168.3.10. You must manually congure the Management port and congure the software image le to start installation.
1 Save the OS10 software image on an SCP/TFTP/FTP server. 2 Power up the device and select ONIE Rescue for manual installation.
3 (Optional) Stop the DHCP discovery if the device boots to ONIE Install.
$ onie-discovery-stop
4 Congure the IP addresses on the Management port, where x.x.x.x represents your internal IP address. Once you congure the
Management port, the response should be up.
$ ifconfig eth0 x.x.x.x netmask 255.255.0.0 up
5 Install the software on the device. The installation command accesses the OS10 software from the provided SCP, TFTP, or FTP URL,
creates partitions, veries installation, and reboots itself.
$ onie-nos-install image location
The OS10 installer image creates several partitions, including OS10-A (active and default) and OS10-B (standby). After installation completes, the system automatically reboots and loads OS10.
Install OS10 manually
ONIE:/ # onie-nos-install ftp://x.x.x.x/PKGS_OS10–Enterprise-10.3.xxP.bin
Where x.x.x.x represents the location to download the image le from, and xxP represents the version number of the software to install.
Install using USB drive
You can manually install the OS10 software image using USB media. Verify that the USB storage device supports a FAT or EXT2 le system. Plug the USB storage device into the USB storage port on the device.
1 Power up the system to automatically boot with the ONIE: Rescue option. 2 (Optional) Stop the ONIE discovery process if the device boots to ONIE: Install.
$ onie-discovery-stop
3 Create a USB mount location on the system.
$ mkdir /mnt/media

Install OS10 license

If OS10 is factory-loaded on your switch, you do not need to install an OS10 license. If you download OS10 on a trial basis, OS10 comes with a 120-day trial license. To continue with uninterrupted use, purchase and install a perpetual license to avoid the OS10 device rebooting every 72 hours.
After you install OS10 and log in, install the license to run the OS10 Enterprise Edition beyond the trial license period. See Download OS10
image and license for complete information. The OS10 license is installed in the /mnt/license directory.
1 Download the License.zip le from DDL as described in Download OS10 image and license. 2 Open the zip le and locate the license le in the Dell folder. Copy the license le to a local or remote workstation. 3 Install the license le from the workstation in EXEC mode.
license install {ftp: | http: | localfs: | scp: | sftp: | tftp: | usb:} filepath/filename
• ftp://userid:passwd@hostip/filepath — Copy from a remote FTP server
• http://hostip/filepath — Copy from a remote HTTP server
• http://hostip — Send request to a remote HTTP server.
• localfs://filepath — Install from a local le directory.
• scp://userid:passwd@hostip/filepath — Copy from a remote SCP server.
• sftp://userid:passwd@hostip/filepath — Copy from a remote SFTP server.
• tftp://hostip/filepath — Copy from a remote TFTP server.
• usb://filepath — Install from a le directory on a storage device connected to the USB storage port on the switch.
• filepath/filename — Enter the directory path where the license le is stored.

Troubleshoot license installation failure
An error message displays if the installation fails.
License installation failed
1 Verify the installation path to the local or remote location you tried to download the license from. 2 Check the log on the remote server to see why the FTP or TFTP le transfer failed. 3 Ping the remote server from the switch — use the ping and traceroute commands to test network connectivity. If the ping fails:
• Check if a Management route is congured on the switch. If not, use the management route command to congure a route to the server network.
• Install the server with the license le on the same subnet as switch.
4 Check if the server is up and running.

Remote access

You can remotely access the OS10 command-line interface (CLI) and the Linux shell. When you install OS10 the rst time, connect to the switch using the serial port.

WARNING
or IPv6 address and static route on a front-end port interface.
To set up remote access to OS10, congure a management route after you assign an IPv4 or IPv6 address to the Management port. The default management route is the path used by a Management port to communicate with a dierent network. Management routes are separate from IPv4 and IPv6 routes and are only used to manage the system through the Management port.
management route 192.168.100.0/24 1.1.1.1 ip route 192.168.100.0/24 2.2.2.2
management route 192.168.200.0/24 managementethernet ip route 192.168.200.0/24 interface ethernet 1/1/1
Congure a management route to the network from which you access the system in CONFIGURATION mode. Repeat the command to congure multiple routes for the Management interface.
management route {ipv4-address/mask | ipv6-address/prefix-length} {forwarding-router-address | managementethernet}
• ipv4-address/mask — Enter an IPv4 network address in dotted-decimal format (A.B.C.D), then a subnet mask in /prex-length format (/xx).
• ipv6-address/prefix-length — Enter an IPv6 address in x:x:x:x::x format with the prex length in /x format (prex range is /0 to /128).
• forwarding-router-address — Enter the next-hop IPv4/IPv6 address of a forwarding router for network trac from the Management port.
• managementethernet — Congures the Management port as the interface for the route, and forces the route to be associated with the Management interface.

CLI Basics

The OS10 command-line interface (CLI) is the software interface you use to access a device running the software — from the console or through a network connection. The CLI is an OS10-specic command shell that runs on top of a Linux-based operating system kernel. By leveraging industry-standard tools and utilities, the CLI provides a powerful set of commands that you can use to monitor and congure devices running OS10.

User accounts

OS10 denes two categories of user accounts — use admin for both the username and password to log into the CLI, or use linuxadmin to log into the Linux shell.

Key CLI features

Consistent command names
Available commands Information about available commands is provided at each level of the CLI command hierarchy. You can enter a
Command completion
Commands that provide the same type of function have the same name, regardless of the portion of the system on which they are operating. For example, all show commands display software information and statistics, and all clear commands erase various types of system information.
question mark (?) at any level and view a list of the available commands, along with a short description of each command.
Command completion for command names (keywords) and for command options is available at each level of the hierarchy. To complete a command or option that you have partially entered, press the Tab key or the Spacebar. If the partially entered letters being a string that uniquely identies a command, the complete command name appears. A beep indicates that you have entered an ambiguous command, and the possible completions display. Completion also applies to other strings, such as lenames, interface names, usernames, and conguration statements.

CLI command modes

The OS10 CLI has two top-level modes:
• EXEC mode — Used to monitor, troubleshoot, check status, and network connectivity.
• CONFIGURATION mode — Used to congure network devices.
When you enter CONFIGURATION mode, you are changing the current operating conguration, called the running conguration. By default, all conguration changes are automatically saved to the running conguration.
You can change this default behavior by switching to the transaction-based conguration mode. To switch to the transaction-based conguration mode, enter the start transaction command. When you switch to the transaction-based conguration mode, you are updating the candidate conguration. Changes to the candidate conguration are not added to the running conguration until you commit them, which activates the conguration. The start transaction command applies only to the current session. Changing the conguration mode of the current session to the transaction-based mode does not aect the conguration mode of other CLI sessions.
• After you explicitly enter the commit command to save changes to the candidate conguration, the session switches back to the default behavior of automatically saving the conguration changes to the running conguration.
• When a session terminates while in the transaction-based conguration mode, and you have not entered the commit command, the changes are maintained in the candidate conguration. You can start a new transaction-based conguration session and continue with the remaining conguration changes.
• All sessions in the transaction-based conguration mode update the same candidate conguration. When you enter the commit command on any session in the transaction-based conguration mode or you make conguration changes on any session in the non- transaction-based mode, you also commit the changes made to the candidate conguration in all other sessions running in the transaction-based conguration mode. This implies that inconsistent conguration changes may be applied to the running conguration. Dell EMC recommends that you only make conguration changes on a single CLI session at a time.
• When you enter the lock command in a CLI session, conguration changes are disabled on all other sessions, whether they are in the transaction-based conguration mode or the non-transaction-based conguration mode. For more information, see
conguration.

CLI command hierarchy

CLI commands are organized in a hierarchy. Commands that perform a similar function are grouped together under the same level of hierarchy. For example, all commands that display information about the system and the system software are grouped under the show
Getting Started
27
system command, and all commands that display information about the routing table are grouped under the show route-map command.

CLI command categories

There are several broad groups of CLI commands available:
set Controls the CLI environment and congure the CLI screen.
ssh Connects to other network systems or to open secure shell connections.
copy Copies les from one location on a device to another, from a device to a remote system, or from a remote system
to a device.
congure Enters CONFIGURATION mode to congure routing protocols, interfaces, network management, and user access.
exit Moves up one command mode. Use the end command to go directly to EXEC mode.
quit Leaves or exits the CLI.

CONFIGURATION Mode

When you initially log in to OS10, you are automatically placed in EXEC mode by default. To access CONFIGURATION mode, enter the configure terminal command. Use CONFIGURATION mode to manage interfaces, protocols, and features.
Interface mode is a sub-mode of CONFIGURATION mode. Interface mode is where you congure Layer 2 and Layer 3 protocols, and IPv4 and IPv6 services specic to an interface:
• Physical interfaces include the Management interface and Ethernet ports
• Logical interfaces include loopback, port-channel, and virtual local area networks (VLANs)
From CONFIGURATION mode, you can also congure L2 and L3 protocols with a specic protocol-conguration mode, such as spanning- tree protocol (STP) or border gateway protocol (BGP).
