Connectivity Guide

2 Check the log on the remote server to nd out 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. Check the
following if ping fails:
• If the remote server is reachable through the management route, check if the management route is congured correctly.
• If the remote server is reachable through a front-panel port, check if the static or dynamic route is present.
4 Install the server with the license le on the same subnet as the switch.
5 Check if the server is up and running.
Zero-touch deployment
Zero-touch deployment (ZTD) allows OS10 users to automate switch deployment:
• Upgrade an existing OS10 image.
• Execute a CLI batch le to congure the switch.
• Execute a post-ZTD script to perform additional functions.
ZTD is enabled by default when you boot up a switch with a factory-installed OS10 for the rst time or when you perform an ONIE: OS
Install
from the ONIE boot menu. When a switch boots up in ZTD mode, it starts the DHCP client on all interfaces — management and
front-panel ports. ZTD congures all interfaces for untagged VLAN trac. The switch obtains an IP address and a ZTD provisioning script
URL from a DHCP server running on the network, and downloads and executes the ZTD script.
• ZTD is supported only in an IPv4 network. ZTD is not supported by DHCPv6.
• At least one of the front-panel ports connected to the network on which the DHCP server is running must be in non-breakout mode.
• After booting up in ZTD mode, if a switch receives no DHCP server response with option 240 within ve minutes, it automatically exits
ZTD mode. During this time, you can abort ZTD by entering the ztd cancel command. The command unlocks the switch
conguration so that you can enter OS10 CLI commands.
• When ZTD is enabled, the command-line interface is locked so that you cannot enter OS10 conguration commands. Only show
commands are available.
According to the contents of the provisioning script, ZTD performs these tasks in this sequence. Although Steps 2, 3 and 4 are each
optional, you must enter a valid URL path for at least one of the IMG_FILE, CLI_CONFIG_FILE, and POST_SCRIPT_FILE variables.
For example, if you only want to congure the switch, enter only a CLI_CONFIG_FILE URL value. In this case, ZTD does not upgrade the
OS10 image and does not execute a post-ZTD script.
1 Downloads the les specied in the ZTD provisioning script — OS10 image, CLI conguration batch le, and post-ZTD script.
• In the provisioning script, enter the le names for the IMG_FILE, CLI_CONFIG_FILE, and POST_SCRIPT_FILE variables as
shown in ZTD provisioning script.
• If no le names are specied, OS10 immediately exits ZTD and returns to CLI conguration mode.
• If the download of any of the specied les fails, ZTD stops. OS10 exits ZTD and unlocks the CLI conguration mode.
2 If an OS10 image is specied for IMG_FILE, ZTD installs the software image in the standby partition. If no conguration le is
specied for
CLI_CONFIG_FILE, ZTD reloads the switch with the new OS10 image.
3 If an OS10 CLI batch le with conguration commands is specied for CLI_CONFIG_FILE, ZTD executes the commands in the
PRE-CONFIG and POST-CONFIG sections. After executing the PRE-CONFIG commands, the switch reloads with the new OS10
image and then executes the POST-CONFIG commands. For more information, see ZTD CLI batch le.
4 If a post-ZTD script le is specied for POST_SCRIPT_FILE, ZTD executes the script. For more information, see Post-ZTD script.
NOTE
: The ZTD process performs a single switch reboot. The switch reboot occurs only if either a new OS10 image is installed
or if the PRE-CONFIG section of the CLI batch le has conguration commands that are executed.
ZTD prerequisites
• Store the ZTD provisioning script on a server that supports HTTP connections.
• Store the OS10 image, CLI batch le, and post-ZTD script on a le server that supports either HTTP, FTP, SFTP, or TFTP connections.
• Congure the DHCP server to provide option 240 that returns the URL of the ZTD provisioning script.
