Enabling TFTP for IPv6

Client and server TFTP for IPv6 is enabled by default on the switch. However, if it is disabled, you can re-enable it by specifying TFTP client or server functionality with the tftp <client|server> command.

Enter the tftp <client|server> command at the global configuration level.


no tftp <client|server [listen <data|both>]>

Enables TFTP for IPv4 and IPv6 client or server functionality so that the switch can:

  • Use TFTP client functionality to access IPv4- or IPv6-based TFTP servers in the network to receive downloaded files.

  • Use TFTP server functionality on the switch to be accessed by other IPv4 or IPv6 hosts requesting to upload files.

The no form of the command disables the client or server functionality.

Default: TFTP client and server functionality enabled


To disable all TFTP client or server operation on the switch except for the auto-TFTP feature, enter the no tftp <client|server> command. To re-enable TFTP client or server operation, re-enter the tftp <client|server> command. (Entering no tftp without specifying client or server affects only the client functionality. To disable or re-enable the TFTP server functionality, you must specify server in the command.)

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

The no tftp <client|server> command does not affect auto-TFTP operation. For more information, see Using auto-TFTP for IPv6.
