Configuring the DNS server

A DNS server is required in the following situations:
•
The TFTP server does not have a host name file. However, devices need to perform the
following tasks:
Use their IP addresses to obtain their host names.
Obtain configuration files named in the format of host name.cfg from the TFTP server.
•
The DHCP server assigns the TFTP server domain name through the DHCP reply message.
Devices must use the domain name to obtain the IP address of the TFTP server.

Configuring the gateway

If the devices to be automatically configured and the servers for automatic configuration reside in
different network segments, you must perform the following tasks:
•
Deploy a gateway and make sure the devices can communicate with the servers.
•
Configure the DHCP relay agent feature on the gateway.
•
Configure the UDP helper feature on the gateway.
When a device sends a request through a broadcast packet to the file server, the UDP helper
changes the broadcast packet to a unicast packet and forwards the unicast packet to the file
server. For more information about UDP helper, see Layer 3—IP Services Configuration Guide.
