Figure 93: Example of switch configuration with SFTP enabled
If you enable SFTP and then later disable it,
TFTP and auto-TFTP remain disabled unless they are explicitly re-enabled.
Operating rules
Prerequisites
To enable SFTP by using an SNMP management application,
you must first disable TFTP and, if configured, auto-TFTP on the switch.
You can use either an SNMP application or the CLI to disable TFTP,
but you must use the CLI to disable auto-TFTP. The following CLI commands
disable TFTP and auto-TFTP on the switch.
Procedure
The TFTP feature is
enabled by default, and can be enabled or disabled through the CLI,
the Menu interface (see
), or an SNMP application. Auto-TFTP is
disabled by default and must be configured through the CLI.
Figure 94: Using the Menu interface to disable TFTP
While SFTP is enabled,
TFTP and auto-TFTP cannot be enabled from the CLI. Attempting to enable
either non-secure TFTP option while SFTP is enabled produces one of
the following messages in the CLI:
SFTP must be disabled before enabling tftp.
SFTP must be disabled before enabling auto-tftp.
Similarly, while SFTP is enabled, TFTP cannot
be enabled using an SNMP management application. Attempting to do
so generates an "inconsistent value" message. (An SNMP management
application cannot be used to enable or disable auto-TFTP.)
