7.1.5 Understanding CLI Error Messages
The CLI provides feedback on commands by displaying informative messages:

Failure reason of a run command. The failure message is identical to the notification
failure message sent by Syslog. For example, an invalid Syslog server IP address is
displayed in the CLI as follows:
(logging)# syslog-ip 1111.1.1.1
Parameter 'SyslogServerIP' does NOT accept the IP-Address:
1111.1.1.1, illegal IPAddress.
Configuration failed
Command Failed!

"Invalid command" message: The command may not be valid in the current command
mode, or you may not have entered sufficient characters for the command to be
recognized. Use "?" to determine your error.

"Incomplete command" message: You may not have entered all of the pertinent
information required to make the command valid. Use "?" to determine your error.
7.2 Enabling CLI
Access to the device's CLI through Telnet and SSH is disabled by default. This section
describes how to enable these protocols.
7.2.1 Enabling Telnet for CLI
The following procedure describes how to enable Telnet. You can enable a secured Telnet
that uses Secure Socket Layer (SSL) where information is not transmitted in the clear. If
SSL is used, a special Telnet client is required on your PC to connect to the Telnet
interface over a secured connection; examples include C-Kermit for UNIX and Kermit-95
for Windows.
For security, some organizations require the display of a proprietary notice upon starting a
Telnet session. You can use the configuration ini file parameter, WelcomeMessage to
configure such a message (see ''Creating a Login Welcome Message'' on page
48 ).

To enable Telnet:
1. Open the Telnet/SSH Settings page ( Configuration tab > System menu >
Management > Telnet/SSH Settings ).
2. Set the ‘Embedded Telnet Server’ parameter to Enable Unsecured or Enable
Secured (i.e, SSL).
3. Configure the other Tenet parameters as required. For a description of these
parameters, see ''Telnet Parameters'' on page
695 .
4. Click Submit , and then reset the device with a burn-to-flash for your settings to take
effect.
