Switches That Will Use Zero Touch Deployment

Switches that will use Zero Touch Deployment with ExtremeCloud IQ or ZTP+ with ExtremeCloud IQ ‑ Site Engine should upgrade to this release by performing the following steps:

Important

Important

When you perform these steps, any prior configuration for this switch is lost.

You do not need to complete this procedure for switches that are already managed by ExtremeCloud IQ or ExtremeCloud IQ ‑ Site Engine; use the upgrade functionality available in ExtremeCloud IQ or ExtremeCloud IQ ‑ Site Engine.

  1. Upgrade to this release from one of the previously described releases, see Validated Upgrade Paths.

  2. Ensure the switch boots without a configuration file. To ensure the switch boots without a configuration file, perform one of the following actions:

    • Rename existing primary and secondary configuration files. Use the mv command to rename the existing configuration files. For example, mv config.cfg config.cfg.backup.

      This is the preferred option because it ensures that the primary and secondary files are removed while making a backup of them at the same time. This option also ensures that the switch uses the default config.cfg file for the final configuration after it has successfully onboarded.

    • Delete the existing primary and secondary configuration files. Create a backup of these files before you delete them.

    • Boot from non-existent configuration files. Use the boot config choice command to configure the primary and backup configuration files to reference files that do not exist on the switch:

      boot config choice primary config-file nonexistent1.cfg

      boot config choice primary backup-config-file nonexistent2.cfg

      This option also works, however, after the switch has successfully onboarded, it does not use the default config.cfg file but uses the alternative configuration file name provided instead, which might not be desired.

  3. Reboot the switch.

Performing these steps results in a switch with a Zero Touch Deployment configuration with the following characteristics:

After the switch reboots in the Zero Touch Deployment configuration, the DHCP client and ExtremeCloud IQ Agent are enabled. The DHCP client obtains an IP address for the switch, DNS discovery is used to discover a Domain Name Server, and the switch attempts to connect to ExtremeCloud IQ and ExtremeCloud IQ ‑ Site Engine.

All switches also receive a Zero Touch Fabric Configuration. For more information, see Fabric Engine User Guide.
