A IPv6 ndd Tunable Parameters
The following IPv6 tunable parameters allow advanced fine-tuning of HP-UX 11i v2 IPv6
performance.
Supported IPv6-related ndd parameters
To obtain a list of supported IPv6-related ndd parameters, enter:
ndd -h supported | grep ip6
NOTE: For more information on a specific parameter (if help text is provided for that
parameter), enter:
ndd -h <parameter>
Table 6 lists the output received from entering, “ndd -h supported | grep ip6”:
