value you need, type it without losing your place in the argument. Leave a space between the keyword and the question
mark. The question mark will not invalidate the command.
When using context-sensitive help, the space (or lack of a space) before the question mark (?) is significant. To obtain a list
of commands that begin with a particular character sequence, type in those characters followed immediately by the
question mark (?). Do not include a space.
Interactive Mode help
The use of help and the ? mark in interactive mode are not the same. To list the options available for a specific command,
type help at the prompt. To see all the enhanced options, enter a space, question mark (?) followed by the enter key. The
behavior differences are shown in the two examples below:
Example 1
C4(config)# interface cable 15/0
Entering cable interface configuration mode for slot 15 MAC port 0
C4(config-cable)# help
authorization-module - Modify authorization module values
cable - Downstream and upstream parameter configuration

igmp - Static join a multicast group on this port
ip - IP address of Cable Interface
proxy-arp - Enable proxy ARP for this cable interface

shutdown - Shutdown both the MAC and Downstream for the interface
spare-group - Configure a CAM sparing group

Example 2
While in interactive mode, if you enter a space and then a question mark (?) followed by the enter key, a list of commands
along with the available show commands will display as shown below. The additional information that you get by using
?
instead of
help
is shown in bold.
