Operator Ports

Success

• The operator completed successfully.
• The operator depends on the patterns specified in User Command Prompt and Switch User Command Prompt to decide if a command (and the operator) succeeds or fails.

  For example, a pattern of ".*#" succeeds the following command: ‘badCmd’:

  1. The operator executes it:

    # badCmd
  

  2. The output is read (which matches .*# prompt):

    badCmd:  not found
    #
  

  3. Execute the next command.

Failure

• The user provides invalid input; for example, negative remote port, negative connection timeout, 0 or negative prompts timeout, blank user command prompt, and so on.
• Unable to log in. Could not match the data read from the Telnet session (within the time to wait for prompts), with the specified User Login Text Prompt pattern.
• Unable to log in. Could not match the data read from the Telnet session (within the time to wait for prompts), with the specified User Password Text Prompt pattern.
• Unable to log in. Could not match the data read from the Telnet session (within the time to wait for prompts), with the specified User Command Prompt pattern.
• Unable to switch user. Could not match the data read from the Telnet session (within the time to wait for prompts), with the specified Switch User Command Prompt pattern.
• Unable to switch user. Could not match the data read from the Telnet session (within the time to wait for prompts), with the specified Switch User Password Text Prompt pattern.
• The user provided incorrect username/password login credentials.
• The user provided incorrect username/password credentials to switch the user.
• Unable to switch to another user unless the username/password scheme is used to log in to the Telnet session.
• The user provided an unknown remote host.
• Telnet connection to the remote host is refused (Telnet is not allowed).
• The username/password provided are not allowed to log in through Telnet.
• The operator could not match the command prompt (specified in User Command Prompt, or Switch User Command Prompt) with the output read from a command within the time to wait for prompts. In this case either:
  • The command finished execution and returned data that did not match the pattern in User Command Prompt, or Switch User Command Prompt.
  • The command’s execution is taking longer than the time to wait for prompts and the operator stopped reading the output data before the command finished. As a result, it did not match the data read with the pattern covered in User Command Prompt, or Switch User Command Prompt. In this case, you must increase the Time to Wait for Prompts to be greater than the execution time of the longest command in the list.

  Note: In this case, any subsequent commands in the list are not executed and the TelnetCommandsOutput only contains the output of the commands that were executed before (including the output read for the current command).
