The latest IPS image will read and convert all commands that begin with the words "ip audit" to "ip ips." For example, theip audit name command will become the ip ips name command.
Although IPS will accept the audit keyword, it will generate the ips keyword when you show the configuration. Also, if you issue the help character (?), the CLI will display the ips keyword instead of the audit keyword, and the Tab key used for command completion will not recognize the audit keyword.
