The following example shows how to display the existing QoS profiles on the CMTS:
Router# show cable qos profile

Profiles 1 and 2 are always created by the CMTS at initial startup. The CMTS dynamically creates
profiles 3 and 4, as shown above, to support Voice over IP (VoIP) codecs G.711 and G.729 when a CM
configures phone lines and uses dynamic service requests to request VoIP service. The remaining
profiles, such as profile 5 above, are typically created by a CM when it comes online.
Profile 3 creates a grant-size of 31.22 KiloBytes per second for G.729 service, and profile 4 creates a
grant-size of 87.2 KiloBytes per second for G.711 service. Both profiles use a default grant-interval of
20 milliseconds. For more information on these profiles, see the TAC technical note at the following

The verbose option was added.
The IP precedence rate enabling bits were added to the display.
This command was deprecated for DOCSIS 1.1 use, because DOCSIS 1.1
replaces the QoS profile model with a service flow model. The
