Setting Up the HDLM Functions
The table below summarizes the functions that can be set in HDLM. For
details about each function, see Setting Up Load Balancing on page 3-135
and subsequent sections.
Each function has a default value and a recommended value. If no function is
set by the HDLM command's set operation, the default value is applied for
each function. The recommended values are used as the guideline values
when functions are configured.
