Note: Before a new upstream channel that is added to a Spectrum Group is
considered for load balancing, the new upstream channel must have at least
one cable modem registered on it. To do this, a user must use the cable
modem ucc command to manually force a cable modem onto the new
upstream channel. After one cable modem is registered on the new upstream
channel, any subsequently registering cable modems will be eligible for load
balancing. Refer to the
Channel
Use the no load-balancing static command in Spectrum Group mode to disable static
upstream load balancing for a Spectrum Group, as follows:
MOT (config-spcgrp:<Spectrum Group name>)# no load-balancing
static
Note: If load balancing is disabled for a Spectrum Group, that specific
Spectrum Group can still be load balanced by including the Spectrum Group
name with the cable load-balance spectrum-group command. If the cable
load-balance spectrum-group command is used without a specific
Spectrum Group name, any Spectrum Groups that have load balancing
disabled will not be load balanced.
If static upstream load balancing is enabled for a Spectrum Group, cable modems are
balanced across the upstream channels within the same Spectrum Group based only
on count. If the cable modem count on the current upstream channel on which the
cable modem is trying to register is greater than the count on the least loaded
upstream channel by a difference of 5, the cable modem is automatically moved to the
least loaded upstream channel.
Note: If a user invokes the load-balance feature through the CLI with the
cable load-balance spectrum-group command (see
