Service Class Definition
Creating a Service Class Definition
To create a service class definition, enter the following command in Configure mode:
The following is a description of the parameters used to create a service class definition:
service <string>Specifies a name for the service class definition. The maximum length is
32 characters.
srv-cat Defines the service category for the service class definition:
cbr Constant Bit Rate provides a guaranteed constant bandwidth
specified by the Peak Cell Rate (PCR). This service category requires
only the PCR value. The Sustainable Cell Rate (SCR) and Maximum
Burst Size (MBS) values are ignored. This service category is intended
for applications that require constant cell rate guarantees such as
uncompressed voice or video transmission.
ubr Unspecified Bit Rate is strictly best effort and runs at the available
bandwidth. Users may limit the bandwidth by specifying a PCR
value. The SCR and MBS are ignored. This service class is intended
for applications that do not require specific traffic guarantees. UBR is
the default.
rt-vbr Real-Time Variable Bit Rate provides a guaranteed constant
bandwidth (specified by the SCR), but also provides for peak
bandwidth requirements (specified by the PCR). This service
category requires the PCR, SCR, and MBS options and is intended for
applications that can accommodate bursty real-time traffic such as
compressed voice or video.
nrt-vbr Non Real-Time Variable Bit Rate provides a guaranteed constant
bandwidth (specified by the SCR), but also provides for peak
bandwidth requirements (specified by the PCR). This service
category requires the PCR, SCR, and MBS options and is intended for
applications that can accommodate bursty traffic with no need for
real-time guarantees.
pcr Specifies the Peak Cell Rate, which defines the maximum cell transmission
rate. The default is 176603 cells/sec. This parameter is valid for CBR, rtVBR,
and nrtVBR service categories. This parameter is optional for UBR.
pcr-kbits Specifies the Peak Cell Rate, which defines the maximum cell transmission
rate, expressed in kbits/sec. The default is 149759 kbits/sec (176603
