Usage Guidelines
This command assigns a default spectrum group to all of the upstreams on the cable interface. All
upstreams on the interface use this spectrum group unless you override this configuration, using one of
the following commands:
•
•
These two commands override the cable spectrum-group command for the particular upstreams to
which they are applied. The remaining upstreams in the interface, however, continue to use the default
configuration that is specified by the cable spectrum-group command.
You must first create and configure the spectrum groups before you can assign them to an interface. To
Tip
create and configure spectrum groups, use the set of cable spectrum-group commands that are available
in global configuration mode.
Examples The following example shows how to assign spectrum group 1 to all of the upstreams on the cable
interface in slot 3/0:
