cells/sec). This is the same as PCR, but is expressed in kbits/sec, and
therefore may be a more convenient form. However, since the natural unit for
ATM is cells/sec, there may be a difference in the actual rate because the
kbit/sec value may not be an integral number of cells. This parameter is valid
for CBR, rtVBR, and nrtVBR service categories. This parameter is optional for
UBR.
scr Specifies the Sustainable Cell Rate which defines the average cell rate. The
default is 0 cells/sec. This parameter is valid only for rtVBR and nrtVBR
service categories.
scr-kbits Specifies the Sustainable Cell Rate which defines the average cell rate. The
default is 0 kbits/sec. This is the same as SCR, but is expressed in kbits/sec,
and therefore may be a more convenient form. However, since the natural
unit for ATM is cells/sec, there may be a difference in the actual rate because
the kbit/sec value may not be an integral number of cells. This parameter is
valid only for rtVBR and nrtVBR service categories.
mbs Specifies the Maximum Burst Size in cells. MBS specifies how many cells can
be transmitted at the Peak Cell Rate. The default is 0 cells. This parameter is
valid only for rtVBR and nrtVBR service categories.
encap Specifies the encapsulation scheme to transport multi protocol data over the
AAL5 layer:
routed-llc Logical link control. This is the default.
routed-vcmux VC-based multiplexing.
oam OAM (Operation, Administration, and Management) loopback cells are used
to provide loopback capabilities and confirm whether a VC connection is up.
Only F5 OAM segments are supported, which provides loopback capabilities
on a VC connection level. This parameter turns OAM ON or OFF on the PVC.
The default is OFF. OAM OFF means that the SSR responds to F5 OAM
requests, but will not generate F5 OAM responses.
Applying a Service Class Definition
To apply a service class definition to a virtual channel, virtual path, or an ATM port, enter
the following command in Configure mode:
The following is a description of the parameters used to apply a service class definition:
service <string>Specifies the name of the service class definition which you want to apply.
The maximum length is 32 characters.
