If one rule is disabled and another enabled at any given time, the C4/c CMTS uses the types, method and threshold
parameters from the rule that is enabled.
If all rules are disabled, there is no load balancing.
In the case of multiple rules enabled at the same time, the C4/c CMTS use the type, threshold, method, and weight
parameters that cause the most active load balancing. Each parameter is chosen independently and may come from
one or more enabled rules.
The following list shows how each parameter is evaluated when multiple rules are enabled for a single policy:
1.
Load Balance Type - the type attributes from all enabled rules are combined such that they are all in force.
2.
The order of preference for method is:
a.
Utilization
b.
Modem Count
3.
The threshold used in the lowest value.
4.
The order of precedence for weight type is:
a.
equal
b.
usOnly
c.
dsOnly
d.
usPlus
e.
dsPlus
Global Load Balance Settings
There are a number of global load balancing attributes, some of which need to be set for periodic load balancing to occur.
These include:
enable - Turn on/off dynamic load balancing for the whole system
general-group-defaults init-technique - Set initialization technique for general groups. Choose from broadcast-
ranging, unicast-ranging, ranging, direct, reinit-mac
general-group-defaults policy - Assign a policy to general group.
