Chapter 4: Using CCM Commands
Accessing the CLI
You may access the CLI in three ways: using the Telnet CLI, using the serial CLI
or entering the CLI access character during a session to a serial device. When
the CLI is accessed, its prompt appears (>), indicating you may type a command.
Entering Commands
At the command prompt, type a command and then press Return or Enter.
When the key is pressed, the command line comprises all characters to the left
of the cursor. The character at the cursor and any characters to the right of the
cursor are ignored. The following table lists the line editing operations for VT100
compatible devices.

Left Arrow If the cursor is not at the beginning of the line, the cursor moves one
character to the left. If the cursor is at the beginning of the line, no
action is taken.
Right Arrow If the cursor is not at the end of the line, the cursor moves one
character to the right. If the cursor is at the end of the line, no

Up Arrow The CLI maintains a buffer containing the last 16 typed command
lines. If there is a previous command line, it will be output as the
current command line and may be edited. If there is no previous
command line in the command line buffer, the command line is set to
blanks and you may enter a new command.
Down Arrow The next command in the CLI command line buffer is made available
for edit. If there is no next command line, the command line is set to
blanks and you may enter a new command.
Delete The character at the cursor position is deleted and all characters to
the right of the cursor position are moved left one character.
