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 corresponding 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, which is named
network.cfg
. The host name file 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 configuration 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
.
