Netboot Configuration
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.
