Maximum downstream data rate in kilobits per second that a modem
using this QoS profile receives. Valid values are from 0 to 100,000.
Default value is 0 (no downstream rate limit).
This option has been deprecated and removed from the CLI,
Note
because its function should be accomplished through the
DOCSIS configuration file.
Maximum upstream data rate in kilobits per second that a modem using
this QoS profile receives. Valid values are from 0 to 100,000. Default
value is 0 (no upstream rate limit).
Arbitrary, unique string to identify this QoS profile. The maximum
length is 32 characters before Cisco IOS Release 12.2(11)BC2, and
80 characters in Cisco IOS Release 12.2(11)BC2 and later.
Relative priority number assigned to upstream traffic by this QoS
profile. Valid values are from 0 to 7, with 7 being the highest priority.
Default value is 0.
Enables Baseline Privacy Interface (BPI) encryption. The default is to
disable BPI encryption.
Overwrite the ToS field in the IP datagrams received on the upstream
before forwarding them downstream (or IP backbone). This parameter
sets the hexadecimal mask bits to the hexadecimal values for the ToS
mask and ToS value, thereby helping the CMTS identify datagrams for
QoS on the backbone.
Each parameter is an 8-bit hexadecimal value that ranges from 0x00 to
0xFF. The default value is 0xFF starting with Cisco IOS Release
12.2(15)BC2 and later, and the default is 0x00 in earlier releases. The
new TOS value is calculated using the following formula:
New ToS = ((Original ToS) AND (NOT tos-mask)) OR tos-value
This formula is how the TOS was calculated in DOCSIS 1.0+
Note
networks before the DOCSIS 1.1 specification was finalized.
For information on the new method of calculating the TOS in
DOCSIS 1.1 networks, see the
Modification
This command was introduced.
This command was included in the Release 12.0 T train.
The value for the max-burst parameter was changed from its original value
of 0 to 255 minislots (as required in the initial DOCSIS 1.0 specification) to
the current, DOCSIS-required value of 0 to 65,535 bytes.
