NOTE:
Specify an IP address for the network calling processor before performing other configurations.
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 or a Layer 3 Ethernet interface) 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 sends a TFTP request to obtain the configuration
file from the specified TFTP server for system initialization. If the client cannot get such parameters,
it performs system initialization without loading any configuration file.
To configure the IP address and name of the TFTP server and the bootfile name in the DHCP address
pool:
Step Command

Specifying a server's IP address for the DHCP client
Some DHCP clients need to obtain configuration information from a server, such as a TFTP server. You
can specify the IP address of that server in each address pool of the DHCP server. The DHCP server sends
the server's IP address to DHCP clients along with other configuration information.
To specify the IP address of a server:
