The zero touch deployment (ZTD) process is enabled by default and starts an automatic discovery process, similar to the ONIE discovery process.
ZTD starts the Dynamic Host Configuration Protocol (DHCP) client on all the interfaces, including management and front-panel ports. ZTD sends DHCP discovery packets with DHCP option 60 (vendor-class specifier) on all the interfaces and listens for the DHCP offer. The DHCP server responds with Option 240 in its response (the DHCP offer). Option 240 includes the valid OS10 image and configuration files. The system proceeds with ZTD, installs OS10 image, and executes the configuration files.
NOTE:The DHCP server response with Option 240 is received through the management port or a front-panel port.
The ZTD auto discovery runs continuously until any of the discovery methods complete or you cancel the ZTD process manually using the
ztd cancel command or you enter into CONFIGURATION mode.
After ZTD completes, use the
show ztd-status command to view the ZTD status. A message similar to the following appears:
OS10# show ztd-status
-----------------------------------
ZTD Status : disabled
ZTD State : completed
Protocol State : idle
Reason : ZTD process completed successfully at Sun Nov 7 09:42:52 2021
