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
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
IMPORTANT:
There must be a space before the keyword ip and keyword 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.
