Two versions of each supported 7750 SR platform software license are currently available: one for non-ZTP bootup, and one for ZTP bootup. Software packages for ZTP bootup contain a bof.cfg file with the auto-boot flag set, which causes the node to automatically boot up in ZTP mode and execute ZTP processes.
The auto-boot flag contains the following information:
client ID
The client ID is sent to the DHCP server to identify the chassis or node and to find a pool for the DHCP offer. If no client ID is configured, the chassis serial number is sent.
This option is used for both IPv4 client ID and IPv6 DUID Type 2.
port (port:vlan)
The port is used to send DHCP discovery; the port number must be configured manually in the BOF.
For more information about the BOF, see Boot options.
