Command Reference Guide
bootfile <name>
Use the bootfile command to specify a fully qualified directory-path name to a file located on a Trivial File
Transfer Protocol (TFTP) server on the network. Some network devices use the file (the path sent to the
Dynamic Host Configuration Protocol version 4 (DHCPv4) client in the DHCPOFFER message) for initial
configuration. Use the no form of this command to remove a configured boot file.
Syntax Description
<name>
Default Values
By default, there is no specified boot file.
Command History
Release 2.1
Functional Notes
RFC 2131 provides specifications for DHCPv4 servers to supply clients with information that allows the
clients to exchange packets with other hosts on the network. DHCPv4 clients that do not store the correct
boot software on an internal flash drive can receive a boot file from a TFTP server. The AOS DHCPv4
server can provide these devices with the address of the network TFTP server and the configuration file
name. For example, some IP phones use this functionality to download the feature and key activation file.
Use the command tftp-server <name> on page 3064
RFC 2131 includes provisions to allow DHCPv4 servers to utilize the 128 octets designated for the boot file
directory-path for expanding the DHCPv4 options field. RFC 1533 outlines the available DHCPv4 variables
for the options field. This process must be negotiated between client and server during the
DHCPDISCOVER process and should only take place if the client specifies a small maxDHCPv4message
size in the DHCPDISCOVER message.
Usage Examples
The following example specifies the location of a TFTP server on the local area network (LAN) at 10.10.0.4
and a boot file of myconfig.cfg (located in the TFTP server root directory) for the DHCPv4 pool
IP_Phones:
(config)#ip dhcp pool IP_Phones
(config-dhcp)#tftp sever 10.10.0.4
(config-dhcp)#bootfile myconfig.cfg
60000CRG0-35E
Specifies a fully qualified directory-path name to the file located on the
network. If the file is located in the root directory of the TFTP server, enter
the file name only.
