Description
Interface bandwidth, in megabits per second (mbps), for the downstream or upstream. The
system uses this value in calculating whether the loads on the interfaces are balanced.
Changing a channel parameter, such as modulation profile or channel width, that affects the
channel's bandwidth also changes the weight value.
How often, in seconds, the Cisco CMTS determines the current load on each cable interface in
the load balance group, as configured using the
Load balancing method being used for this load balance group, as configured using the
load-balance group (global configuration)
Thresholds configured for this load balance group, as configured using the
group threshold
command:
Minimum = Minimum difference in the number of cable modems or service flows that can
•
exist on two interfaces in the group before cable modems are moved between the
interfaces. If the imbalance between interfaces is below this value, cable modems are not
moved. This field contains a value only when the group is configured for the modems or
service-flows method of load balancing. (This value is configured using the load
minimum option of the
Static = Minimum difference in the percentage of total load that must exist between
•
interfaces in a load-balance group before the Cisco CMTS performs static load balancing.
When the load between interfaces is greater than this value, cable modems that are in the
process of registering with the CMTS are moved between interfaces until the load
difference is again below this value. (This value is configured using the load option of the
cable load-balance group threshold
Enforce = Minimum difference in the percentage of total load that must exist between
•
interfaces in a load-balance group before the Cisco CMTS performs dynamic load
balancing and begins moving cable modems that are currently online. When the difference
in load between two interfaces falls below this value, the CMTS stops dynamic load
balancing and performs static load balancing. (This value is configured using the enforce
option of the
cable load-balance group threshold
Ugs = Percentage of the bandwidth that is allocated for Unsolicited Grant Services (UGS)
•
traffic, such as Voice-over-IP (VoIP), that is in use on an interface because the CMTS
moves cable modems that are online with active UGS service flows. (This value is
configured using the ugs option of the
Source downstream or upstream interface that is part of a cable load balance group. If the
Target field contains a value, this indicates that this source interface is currently
oversubscribed, and that the CMTS is trying to reduce its load by moving cable modems from
the source interface to the target interface.
