Enabling TFTP

TFTP is enabled by default on the switch. If TFTP operation has been disabled, you can re-enable it by specifying TFTP client or server functionality with the tftp <client server> command at the global configuration level.

Syntax: [no] tftp <client server [listen <oobmdataboth>]>

Disables/re-enables TFTP for client or server functionality so that the switch can:

• Use TFTP client functionality to access TFTP servers in the network to receive downloaded files.

• Use TFTP server functionality to upload files to other devices on the network.

• For switches that have a separate out-of-band management

 

port, the listen parameter in a server configuration allows you

 

to specify whether transfers take place through the out-of­

 

band management (oobm) interface, the data interface, or

 

both. Refer to Appendix I, “Networked Out-of-Band

 

Management (OOBM)” in this guide for more information

 

on out-of-band management.

 

 

U s a g e N o t e s

To disable all TFTP client or server operation on the switch except for the

 

auto-TFTP feature, enter the no tftp <client server> command.

 

When ip ssh file transfer is used to enable SCP and SFTP functionality on the

 

switch, this will disable TFTP client and server functionality. Once ip ssh file

 

transfer is enabled, TFTP and auto-TFTP cannot be re-enabled from the CLI.

 

When TFTP is disabled, instances of TFTP in the CLI copy command and the

 

Menu interface “Download OS” screen become unavailable.

 

The no tftp <client server> command does not disable auto-TFTP operation.

 

To disable an auto-TFTP command configured on the switch, use the no auto­

 

tftp command described on page A-11to remove the command entry from the

 

switch’s configuration.

 

For information on how to configure TFTP file transfers on an IPv6 network,

 

refer to the “IPv6 Management Features” chapter in the IPv6 Configuration

 

Guide for your switch.
