Accessing Help
Enter help or ? in normal or privileged mode to see the commands available in those modes. Command
usage, the help menu, and, when appropriate, parameter ranges are provided if you enter a command
using the wrong number of arguments or inappropriate arguments.
Additionally, appending ? to a command displays a list of valid keywords and arguments for the
command. Insert a space between the last parameter and the question mark (?). For example, eight
parameters are used by the set mls command. To see these parameters, enter set ip ? at the privileged
mode prompt. The system displays all valid keywords and arguments as follows:
Console> (enable) set ip ?
alias Set alias for IP Address
dns Set DNS information
fragmentation Set IP fragmentation enable/disable
http Set IP HTTP server information
