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 file 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 configured 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 file 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 file to configure 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 first 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 configures all interfaces for untagged VLAN traffic. 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 five minutes, it
automatically exits ZTD mode. During this time, you can abort ZTD by entering the ztd cancel command. The command
unlocks the switch configuration so that you can enter OS10 CLI commands.
● When ZTD is enabled, the command-line interface is locked so that you cannot enter OS10 configuration 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 configure 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 files specified in the ZTD provisioning script — OS10 image, CLI configuration batch file, and post-ZTD script.
● In the provisioning script, enter the file names for the IMG_FILE, CLI_CONFIG_FILE, and POST_SCRIPT_FILE
variables as shown in ZTD provisioning script.
● If no file names are specified, OS10 immediately exits ZTD and returns to CLI configuration mode.
● If the download of any of the specified files fails, ZTD stops. OS10 exits ZTD and unlocks the CLI configuration mode.
2. If an OS10 image is specified for IMG_FILE, ZTD installs the software image in the standby partition. If no configuration file
is specified for CLI_CONFIG_FILE, ZTD reloads the switch with the new OS10 image.
3. If an OS10 CLI batch file with configuration commands is specified 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 file.
4. If a post-ZTD script file is specified for POST_SCRIPT_FILE, ZTD executes the script. For more information, see Post-ZTD
script.
