Netboot Configuration - Lenovo RackSwitch G8264 Command Reference Manual

Netboot Configuration

© Copyright Lenovo 2017
Netboot allows the switch to automatically download its configuration file over the
network during switch reboot and apply the new configuration. Upon reboot, the
switch includes the following options in its DHCP requests:
 Option 66 (TFTP server address)
 Option 67 (file path)
If the DHCP server returns the information, the switch initiates a TFTP file transfer
and loads the configuration file into the active configuration block. As the switch
boots up, it applies the new configuration file. Note that the option 66 TFTP server
address must be specified in IP‐address format (host name is not supported).
If DHCP is not enabled, or the DHCP server does not return the required
information, the switch uses the manually‐configured TFTP server address and file
path.
