Configuring the TFTP server and bootfile name for the client
For the DHCP server to support client auto-configuration, you must specify the IP address or name of a
TFTP server and the bootfile name in the DHCP address pool. You do not need to perform any
configuration on the DHCP client.
The DHCP client uses these parameters to contact the TFTP server and request the configuration file used
for system initialization.
1.
When a router starts up without loading any configuration file, the system sets an active interface
(such as the interface of the default VLAN) as the DHCP client to request from the DHCP server for
parameters, such as an IP address and name of a TFTP server, and the bootfile name.
2.
After getting related parameters, the DHCP client will send a TFTP request to obtain the
configuration file from the specified TFTP server for system initialization. If the client cannot get
such parameters, it will perform system initialization without loading any configuration file.
When Option 55 in the client’s request contains parameters of Option 66, Option 67, or Option 150, the
DHCP server will return the IP address or name of the specified TFTP server, and bootfile name to the
client.
Follow these steps to configure the IP address and name of the TFTP server and the bootfile name in the
DHCP address pool:
