Configuring the TFTP Server

78-6511-05
If you do not configure the DHCP server with the lease options described earlier,
then it replies to client requests with only those parameters that have available
values. If the IP address and subnet mask are not in the reply, the switch is not
configured. If the DNS server IP address, router IP address, or TFTP server name
are not found, the switch might broadcast TFTP requests. Unavailability of other
lease options does not affect autoconfiguration.
If the configuration file on the switch does not contain the IP address, the
switch obtains its address, mask, gateway IP address, and host name from
DHCP. If the service config global configuration command is specified in the
configuration file, the switch receives the configuration file through TFTP
requests. If the service config global configuration command and the IP
address are both present in the configuration file, DHCP is not used, and the
switch obtains the default configuration file by broadcasting TFTP requests.
The DHCP server can be on the same or a different LAN as the switch. If it is on
a different LAN, the switch must be able to access it through a relay device. The
DHCP server can be running on a UNIX or Linux operating system; however, the
Windows NT operating system is not supported in this release.
For more information, see the
page 6-9. You must also set up the TFTP server with the switch configuration
files; for more information, see the next section.
For CLI procedures, refer to the Cisco IOS Release 12.0 documentation on
Cisco.com for additional information and CLI procedures.
The TFTP server must contain one or more configuration files in its base
directory. The files can include the following:
The configuration file named in the DHCP reply (the actual switch
•
configuration file)
The network-confg or the cisconet.cfg file (known as the default
•
configuration files)
• The router-confg or the ciscortr.cfg file (These files contain commands
common to all switches. Normally, if the DHCP and TFTP servers are
properly configured, these files are not accessed.)
