Router(config)# cable load-balance docsis30-enable static
Router(config)# end
Enable DOCSIS 3.0 General Load Balance Group
To enable general load balance group, use cable load-balance docsis-group command as shown here:
Router# configure terminal
Router(config)# cable load-balance docsis-group fn 1 md c3/0/1
Router(config-lb-group)# no disable
Router(config-lb-group)# end
Enable Dynamic Load Balance and Fixed-Primary Channel Movement
To balance the load of all downstream channels based on utilization, enable dynamic load balance by running
the following commands:
Router#
configure terminal
Router(config)# cable load-balance docsis30-enable dynamic downstream
Router(config)# end
Fixed primary channel movement is disabled by default. With dynamic load balancing enabled, we recommend
that you enable fixed primary channel movement to reduce service outage by running the following commands:
Router#
configure terminal
Router(config)#
cable load-balance fixed-primary-channel
Router(config)# end
Verify Static Load Balancing Configuration
This section describes how to use show commands to verify the configuration of the static load balancing.
Check the load of all primary channels using the show cable load-balance docsis-group load command as
shown here:
Router# show cable load-balance docsis-group fn 1 md c3/0/1 load | in In

This command output lists all primary channels and shows the number of cable modems used with these
channels. NBCM is the number of narrowband modems used with a channel while WBCM (WB/UB) is the
number of wideband modems used with a channel. The total number of WBCMs must be balanced among
all channels.
The difference between the total number of WBCMs used with any two channels is smaller or equal to the
minimum threshold load. The default value of the minimum threshold load is 5.
