(Optional) Configuring a Configuration File for a DHCP Client

Context

DHCP can be used to deliver configuration files to clients that require them for startup. You can save the configuration files on the DHCP server or specify the IP address of a dedicated file server. When a configuration file exists on a dedicated file server, the DHCP server needs to specify the IP address of the file server for clients. You can also specify an IP address for the file server by configuring user-defined options for clients.

If the startup configuration file is saved on a file server, the route between the DHCP client and file server must be reachable.

Procedure
