KB.15.15

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

Default: TFTP client and server functionality enabled

NOTE: 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 and the Menu interface

"Download OS" screen become unavailable.

The no tftp [ client|server ] command does not affect auto-TFTP operation. For more

information, see “Using auto-TFTP for IPv6” (page 48).

Copying files over IPv6 using TFTP

Syntax:

copy tftp target ipv6-addr filename [ oobm ]

Copies (downloads) a data file from a TFTP server at the specified IPv6 address to

a target file on a switch that is enabled with TFTP server functionality.

ipv6-addr

If this is a link-local address, use this IPv6 address format:

fe80::device-id %vlan vid

For example:

fe80::123%vlan10

If this is a global unicast address, use this IPv6 format:

ipv6-addr

For example:

2001:db8::123

target

One of the following values:

autorun-cert-file

Copies an autorun trusted certificate to the switch.

autorun-key-file

Copies an autorun key file to the switch.

command-file

Copies a file stored on a remote host and executes the ACL command script

on the switch. Depending on the ACL commands stored in the file, one of

the following actions is performed in the running-config file on the switch:

• A new ACL is created.

• An existing ACL is replaced.

• match, permit, or deny statements are added to an existing ACL.

For more information on ACLs, see "Creating an ACL Offline" in the

“Access Control Lists (ACLs)” chapter in the Access Security Guide.
