Chapter 2 Cisco CMTS Configuration Commands
cable load-balance group threshold
register because the provisioning system has sent them the wrong DOCSIS configuration files. If the
Cisco CMTS detects such unstable situations, it does not load balance cable modems from those
interfaces until the system stabilizes. However, if the system instability persists, you should increase the
threshold values using the
cable load-balance group threshold
command until the system stabilizes.
Examples
The following example shows how to configure load-balance group 2 so that it performs static load
balancing when the difference between two cable interfaces in the group is 20 percent or more.
Router#
config terminal
Router(config)#
cable load-balance group 2 threshold load 20
Router(config)#
The following example shows how to configure load-balance group 5 so that it performs static load
balancing when the difference in usage between two cable interfaces in the group is 20 percent or more,
and so that it performs dynamic load balancing when the difference in usage is 30 percent or more. The
Cisco CMTS will also begin moving cable modems with active UGS service flows when UGS service
flows reach 60 percent of the total bandwidth available on the upstream channel.
Router(config)#
cable load-balance group 5 threshold load 20 enforce 30
Router(config)#
cable load-balance group 5 threshold ugs 60
Router(config)#
cable load-balance group 5 policy ugs
Router(config)#
Note
You must configure the load-balance group with the
cable load-balance group policy ugs
command
before the Cisco CMTS begins enforcing the threshold that was set with the
cable load-balance group
threshold ugs
command.
