HH Network Profile II Configuration Topology
The None Profile
The None profile is different from the profiles described previously
because it has no pre-defined parameters. You must set all the
parameters manually.
To set the parameters, choose either Fast or Medium from the HH
Network/Token Group dialog box, and click Apply. This presets the
parameters according to the profile.
To enable manual changes and activate the entry fields, choose None
and click Apply again. The former parameter settings will be
overridden and can then be changed.
Because the profiles Fast and Medium cover nearly all conceivable
network topologies, None is recommended for evaluation purposes
only. An extensive knowledge of the functions of the parameters, their
value ranges, and their impact on the availability of the network is
required for proper manual parameterization.
