2.5.10 Configuring the TFTP Server and Bootfile Name for the Client

This task is to specify the IP address and name of a TFTP server and the bootfile name
in the DHCP address pool. The DHCP clients use these parameters to contact the
TFTP server, requesting the configuration file used for system initialization, which is
called auto-configuration. The request process of the client is described below:
1) When a swtich starts up without loading any configuration file, the system sets an
active interface (such as the VLAN interface of the default VLAN) as the DHCP
client to request from the DHCP server 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.
To implement auto-configuration, you need to specify the IP address and name of a
TFTP server and the bootfile name in the DHCP address pool on the DHCP server, but
you do not need to perform any configuration on the DHCP client.
Note:
Currently, S7500E series Ethernet switches do not support the auto-configuration
function, but they can assign parameters such as TFTP server addresses to devices
that support auto-configuration when they are used as DHCP servers.
When option 55 in the requesting client message contains parameters of option 66,
option 67, or option 150, the DHCP server will return the IP address and 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:
Enter system view
Enter DHCP address
pool view
Specify the TFTP
server
Specify the name of
the TFTP server
To do... Use the command...
system-view
dhcp server ip-pool
pool-name
tftp-server ip-address
ip-address
tftp-server domain-name
domain-name
