Setting the CLP Bit for ATM Cells

By setting the Cell Loss Priority (CLP) bit in ATM cells, you can redefine the drop probability of ATM cells
when the network becomes congested.
Follow these steps to set the CLP bit for ATM cells:
To do...
Set the PVC's
service type to
constant bit rate
(CBR)
Set the PVC's
service type to
unspecified bit
rate (UBR), and
set the
rate-related
parameters
Set the PVC's
service type to
variable bit
rate-non real
time (nrt_VBR),
and set the
rate-related
parameters
Set the PVC's
service type to
variable bit
rate-real time
(rt_VBR), and
set the
rate-related
parameters
Use the command...

Remarks
Optional
By default, aal5snap encapsulation
is adopted.
Optional
By default, OAM F5 Loopback cell
transmission is disabled. However,
if an OAM F5 Loopback cell is
received, it should be responded.
By default, up-count is 3,
down-count is 5 and
retry-frequency is 1 second.
Optional
By default, AIS/RDI alarm cell
detection is enabled, which means
the PVC goes down when the
number of AIS/RDI alarm cells
received reaches down-count and
goes up if no AIS/RDI alarm cell is
received in a period specified by
the up-count argument (in
seconds).
Optional
By default, the service type of a
PVC is UBR.
The CDVT is 500μs by default.
You can use these four commands
to set the service type and the
parameters concerning
transmission rate. Note that a
newly configured service type
overwrites the existing one.
