Examples
The following example shows how to display the existing QoS profiles on the CMTS:
Router#
show cable qos profile
ID Prio Max Guarantee Max Max TOS TOS Create B IP prec.
upstream upstream downstream tx mask value by priv rate
bandwidth bandwidth bandwidth burst enab enab
1 0 0 0 0 0 0x0 0x0 cmts(r) no no
2 0 64000 0 1000000 0 0x0 0x0 cmts(r) no no
3 7 31200 31200 0 0 0x0 0x0 cmts yes no
4 7 87200 87200 0 0 0x0 0x0 cmts yes no
5 2 256000 0 128000 1503 0x0 0x0 cm no no
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 following example displays detailed output for profile 1:
Router#
show cable qos profile 1 verbose
profile-index
Displays cable QoS table. Valid range is 1 to 255.
verbose
Displays detailed information about the QoS profiles.
Release
Modification
11.3NA
This command was introduced.
12.0(3)T
The command was included in the mainline release.
12.0(7)XR
The
verbose
option was added.
12.1(1)T
The IP precedence rate enabling bits were added to the display.
12.1(4)CX
This command was deprecated for DOCSIS 1.1 use, because DOCSIS 1.1
replaces the QoS profile model with a service flow model. The
show
interface cable qos paramset
command is used for DOCSIS 1.1 operation.
