administrator can Telnet to each device to perform specific configurations (for example, configure
the IP address of each interface).
• If devices use different configuration files, you need to configure static address pools to ensure that
each device can get a fixed IP address and a specific configuration file. With this method, the
administrator does not need to perform any other configuration for the devices.
NOTE:
To configure static address pools, you must obtain client IDs. To obtain a device’s client ID, use the display
dhcp server ip-in-use command to display address binding information on the DHCP server after the
device obtains its IP address through DHCP.
Obtaining the configuration file from the TFTP server
File types
A device can obtain the following files from the TFTP server during automatic configuration:
• The configuration file specified by the Option 67 or file field in the DHCP response
• The host name file named network.cfg, which stores mappings between IP addresses and host
names.
For example, the host name file can include the following:
ip host host1 101.101.101.101
ip host host2 101.101.101.102
ip host client1 101.101.101.103
ip host client2 101.101.101.104
CAUTION:
• There must be a space before the keyword ip host.
• The host name of a device saved in the host name file must be the same as the confi
g
uration file name
of the device, and can be identical with or different from that saved in the DNS server.
• The configuration file of a device is named hostname.cfg, where hostname is the host name of the
device. For example, if the host name of a device is aaa, the configuration file of the device is
named aaa.cfg.
• The default configuration file is named device.cfg.
