Figure 3-9. Example of Help for a Specific Instance of a Command

Note that if you try to list the help for an individual command from a privilege level that does not include that command, the switch returns an error message. For example, trying to list the help for the interface command while at the global configuration level produces this result:

HP2512# interface help

Invalid input: interface

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 2512 and 2524 offer 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):

Line Command the Using (CLI) Interface

HP2512(config)# interface e 5-8

HP2512(eth-5-8)#

HP2512(eth-Trk1)#

Command executed at configuration level for entering port or trk1 static trunk-group context.

Resulting prompt showing port or static trunk contexts.
