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 CPS appliance IP address with a Server Set command, a reboot is required before the change becomes effective. In these cases, the CPS database is updated when you enter the command and you are prompted that the change will not take effect until the CPS 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 CPS appliance are terminated.

Understanding Conventions

This section describes the parts of a CPS 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.
