Table 4.2 lists the line editing operations for ASCII TTY devices. There is no command line buffer
available on an ASCII TTY device.

When commands take effect

Each command is completely processed before the next command may be entered. Some
commands prompt for confirmation before they are processed. In these cases, you must confirm or
cancel by entering

Y

or

N

respectively.

If you enter a Server FLASH command or if you change the CCM appliance IP address with a Server
Set command, a reboot is required before the change becomes effective. In these cases, the CCM
database is updated when you enter the command and you are prompted that the change will not take
effect until the CCM appliance reboots. You may choose to reboot at that time, or you may decline.
When the unit reboots, your session and all other sessions on the CCM appliance are terminated.

Understanding Conventions

This section describes the parts of a CCM appliance command and the conventions used in this
document to describe a command’s syntax.

Command syntax

A command may have four types of syntax: positional commands, positional parameters, keyword
parameters and keyword values. The following examples demonstrate the syntax types.
The following Set Port command changes the baud rate and flow control settings for port 2.

> PORT 2 SET BAUD=57600 FLOW=XONXOF
