Debugging A Feature Module - HP 5500 EI Series Configuration Manual

• Screen output switch—Controls whether to display the debugging information on a certain screen.
As shown in Figure 3, assume that the device can provide debugging for the three modules 1, 2, and 3.
The debugging information can be output on a terminal only when both the protocol debugging switch
and the screen output switch are turned on.
Output of debugging information depends on the configurations of the information center and the
debugging commands of each protocol and functional module. Debugging information is typically
displayed on a terminal (including console or VTY) for display. You can also send debugging
information to other destinations. For more information, see "Configuring the information center."

Debugging a feature module

Output of debugging commands is memory intensive. To guarantee system performance, enable
debugging only for modules that are in an exceptional condition. When debugging is complete, use the
undo debugging all command to disable all the debugging functions.
Configure the debugging, terminal debugging, and terminal monitor commands before you can display
detailed debugging information on the terminal. For more information about the terminal debugging
and terminal monitor commands, see Network Management and Monitoring Command Reference.
