Enable DOCSIS 3.0 General Load Balance Group

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
Interface
In3/0/1:0(573 MHz)
In3/0/1:4(597 MHz)
In3/0/1:8(621 MHz)
In3/0/1:12(645 MHz) initial 2147557888 0%(0%/0%)
In3/0/1:16(669 MHz) initial 2147557888 0%(0%/0%)
In3/0/1:20(693 MHz) initial 2147557888 0%(0%/0%)
In3/0/1:24(717 MHz) initial 2147557888 0%(0%/0%)
In3/0/1:28(741 MHz) initial 2147557888 0%(0%/0%)
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.
