Chapter 2      Cisco CMTS Configuration Commands

cable load-balance group threshold

Defaults

The 

load

 parameter defaults to 10 percent, the 

load minimum 

parameter defaults to 5, the 

stability

 

parameter defaults to 50 percent, and the 

ugs

 parameter defaults to 70 percent. By default, only static 

load balancing is done (no 

enforce

 option). If the 

enforce

 option is given without a threshold value, it 

defaults to the same value as the 

load

 parameter.

Command History

Usage Guidelines

The 

cable load-balance group threshold 

command configures a load-balance group for the threshold 

values that it should use to determine when a cable modem should be moved to a new downstream or 
upstream. You can specify the following different thresholds:

•

load

—Specifies the maximum load usage that can exist between interfaces in a load-balance group 

before the Cisco CMTS begins static load-balancing operations. The default value of 

load-value

 is 

10 percent, which means that two upstreams or two downstreams can have usage rates that vary up 
to 10 percent before the Cisco CMTS begins rebalancing the load usage. This rebalancing, however, 
is done only when cable modems first register with the Cisco CMTS—the Cisco CMTS does not 
switch cable modems that are already online. 

For example, if the 

load

 value is 10 percent, and upstream 1 is at 23 percent and upstream 2 is at 30 

percent, no cable modems are moved. However, if load usage for upstream 2 reaches 35 percent, the 
Cisco CMTS begins assigning new cable modems, as they register, to upstream 1 until the difference 
in load usage between the two upstreams falls below 10 percent. 

Note

The default of 10 percent is the minimum recommended threshold. Do not set this threshold 
below 10 percent unless you have been instructed to do so by Cisco TAC. 

•

enforce

—Enables dynamic load balancing, so that the Cisco CMTS can move cable modems that 

are already online. This option has its own threshold value, which specifies the difference in load 
usage that must exist between two interfaces in a group before the Cisco CMTS begins moving 
online cable modems. The Cisco CMTS continues to move cable modems until the difference in load 
usage rates falls below the threshold value. 

When using dynamic load balancing and an upstream channel is overloaded, the Cisco CMTS sends 
an Upstream Channel Change (UCC) request to a cable modem to instruct it to move to another 
upstream. The cable modem should move to the new upstream channel, without going offline or 
having to reregister with the CMTS. 

When using dynamic load balancing and a downstream channel is overloaded, the Cisco CMTS 
sends an abort response to a cable modem’s ranging request (RNG-REQ) message. When the cable 
modem sends a new REG-REQ message, the Cisco CMTS specifies the new downstream channel in 
the Downstream Frequency Override field in its REG-RSP message. The cable modem must go 
offline and reregister on the new downstream channel, so as to conform to the DOCSIS 1.0 
specifications.
