Chapter 2 Cisco CMTS Configuration Commands
cable load-balance group (interface configuration)
Note
If both downstreams and upstreams are assigned to the same load-balance group, the
Cisco CMTS attempts to balance both the downstream and upstream values when it moves
cable modems.
•
If the load-balance group includes downstream interfaces, you must also configure the downstream
center frequency on those interfaces, using the
cable downstream frequency
cable interface
command. This command is informational-only on cable interfaces that use an external upconverter,
but it is required for load balancing, so that the Cisco CMTS knows where to move cable modems
when it is load balancing downstreams.
•
Load balancing is done only on a per-chassis basis—all interfaces in a load-balance group must be
in the same chassis.
Note
In Cisco IOS Release 12.2(15)BC1, you can configure an interface for both load balancing and Hot-
Standby Connection-to-Connection (HCCP) N+1 redundancy, but load balancing does not continue after
a switchover from a Working to a Protect interface. Load balancing resumes when the Cisco CMTS
switches back to the Working interface.
Examples
The following example shows how to assign the first downstream on the cable interface line in slot five
to load balance group 5:
Router#
config terminal
Router(config)#
interface cable 5/0
Router(config-if)#
cable load-balance group 5
Router(config-if)#
