Displaying Help for an individual command.
Syntax:
<command-string> help
This option displays Help for any command available at the current context level.
For example, to list the Help for the interface command in the Global Configuration privilege level:
Example 15 How to display help for a specific command
HP Switch(config)# interface help
Usage: [no] interface < [ethernet] PORT-LIST [...] | loopback <num> >
Description: Enter the Interface Configuration Level, or execute one
command for that level. Without optional parameters
specified, the 'interface' command changes the context to
the Interface Configuration Context Level for execution of
configuration changes to the port or ports in the PORT-LIST
or with loopback keywork it will change context to loopback
mode. Use 'interface ?' to get a list of all valid commands.
Note that trying to list the help for an individual command from a privilege level that does not
include that command results in an error message. For example, trying to list the help for the
interface command while at the global configuration level produces this result:
HP Switch# speed-duplex help
Invalid input: speed-duplex
Configuration commands and the context configuration modes
You can execute any configuration command in the global configuration mode or in selected
context modes. However, using a context mode enables you to execute context-specific commands
faster, with shorter command strings.
The switch offers interface (port or trunk group) and VLAN context configuration modes:
Port or trunk-group context. Includes port-or trunk-specific commands that apply only to the selected
port(s) or trunk group, plus the global configuration, Manager, and Operator commands. The
prompt for this mode includes the identity of the selected port(s):
HP Switch(config)# interface c3-c6
HP Switch(eth-C5-C8)#
HP Switch(config)# interface trk1
HP Switch(eth-Trk1)#
Commands executed at configuration level for entering port and trk1 static
trunk-group contexts, and resulting prompts showing port or static trunk contexts..
HP Switch(eth-C5-C8)#
