cable load-balance group (global configuration)
cable load-balance group (global configuration)
To create a load-balance group and configure the type of load-balancing to be used, use the cable load-
balance group command in global configuration mode. To delete a load-balance group, use the no form
of this command. To reset a load-balance group to its default configuration, use the default form of this
command.
Syntax Description n
method modem
method service-flows
method utilization
Defaults No load-balance groups are created. By default, a load-balance group uses the actual number of cable
modems online each interface to determine load balancing needs (modem option).
Note If you do not create any load-balance groups, the Cisco CMTS defaults to using a form of registration-
based load balancing that attempts to equally distribute cable modems among upstreams at the time the
cable modems register and come online. No load balancing is done for downstreams or for cable modems
that are already online.

cable load-balance group n [method utilization | method modem | method service-flows]
no cable load-balance group n
Specifies the number of the load-balance group. The valid range is 1 to 20.
Note
(Optional) Specifies that the load-balance group should use the number of
active cable modems on an interface to determine the current load (default).
This method does not take into account the amount of traffic flowing
through those particular cable modems.
(Optional) Specifies that the load-balance group should use the number of
active service flow IDs (SFIDs) on an interface to determine the current
load.
(Optional) Specifies that the load-balance group should use an interface's
current percentage of utilization to determine the current load.
Tip
You can create a maximum of 20 load-balance groups on each
chassis. However, you can reuse those load-balance groups on
different sets of cable interfaces, as long as they are in different
domains. If downstreams are not included in a load-balance group,
then each downstream can be considered a separate domain.
The utilization method does not begin moving cable modems for
load balancing until the utilization of the interface is at 25 percent
or more. This is done to avoid the unnecessary moving of cable
modems due to temporary spikes in an interface's utilization rates.
