Step Command Remarks
6. Enable the OAM
continuity check (CC)
function.
oam cc end-to-end { both |
sink | source }
Optional.
By default, OAM CC is disabled.
• When you configure OAM CC on a PVC,
you must configure one end of the PVC as
the source and the other end as the sink.
• On a PVC with the OAM CC function
enabled, if the detecting end fails to
receive CC cells within 3 seconds, the
state of the PVC changes to down and
will change to up only after CC cells or
packets are received again.
• When disabling OAM CC on a PVC, you
must make sure that the role of the PVC in
continuity check is the same as the one
that has been enabled. For example, if
you have enabled the PVC as both the
CC cell source and the sink, you should
perform the undo oam cc end-to-end
both command rather than the undo oam
cc end-to-end sink command to disable
the function.
• This command cannot be configured on
the PVCs in a PVC group.
7. Set the service type and
rate-related parameters for
the PVC.
• Set the service type to
constant bit rate (CBR):
service cbr output-pcr
[ cdvt cdvt-value ]
• Set the service type to
unspecified bit rate
(UBR), and set the
rate-related parameters:
service ubr output-pcr
• Set the service type to
nrt_VBR, and set the
rate-related parameters:
service vbr-nrt
output-pcr output-scr
output-mbs
• Set the service type to
rt_VBR, and set the
rate-related parameters:
service vbr-rt output-pcr
output-scr output-mbs
Optional.
By default, the service type of a PVC is UBR.
You can use any of these four commands to
configure a service type and its rate
parameters for a PVC.
Note the following:
• A newly configured service type
overwrites the old one.
• Setting of the arguments cdvt-value,
output-scr, and output-mbs does not take
effect on the router.
Configuring applications carried by ATM
IPoA, IPoEoA, and EoA are mutually exclusive on an ATM PVC.
