Step Command Remarks
8. Set the maximum number of
BDs allowed.
tx-bd-limit
value
Optional.
The value range for the value
argument varies with interface
card models.
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.
To set the CLP bit for ATM cells:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Create a class and enter
class view.
traffic classifier
tcl-name
[
operator
{
and
|
or
} ]
N/A
3. Configure the match criteria.
if-match
[
not
]
match-criteria
N/A
4. Return to system view.
quit
N/A
5. Create a traffic behavior and
enter traffic behavior view.
traffic behavior
behavior-name
N/A
6. Mark the CLP bit for ATM
cells.
remark atm-clp
atm-clp-value
Optional.
By default, the CLP bit is not
marked for ATM cells.
The CLP bit of ATM cells is 0 or 1.
When congestion occurs, ATM
cells with CLP bit 1 are dropped
preferentially.
7. Return to system view.
quit
N/A
8. Create a policy and enter
policy view.
qos policy
policy-name
N/A
9. Associate the class with the
traffic behavior in the policy.
classifier
tcl-name
behavior
behavior-name
N/A
10. Return to system view.
quit
N/A
11. Enter ATM interface or
subinterface view.
interface atm
{ interface-number
| interface-number.subnumber }
N/A
12. Create a PVC and enter
PVC view.
pvc
{ pvc-name [ vpi/vci ] |
vpi/vci }
By default, no PVC is created.
13. Apply the QoS policy on the
PVC.
qos apply policy
policy-name
{
inbound
|
outbound
}
N/A

Router Series Comware 5 ACL and QoS Configuration Guide.
Assigning a transmission priority to an ATM PVC
You can assign transmission priorities to ATM PVCs associated with the UBR, rt-VBR, or nrt-VBR
service. At the time of bandwidth allocation, the PVC with higher priority has priority over other PVCs.
