Re-marking the CLP flag value of ATM cells

You can re-mark the cell loss priority (CLP) flag value of ATM cells to specify the drop precedence for the cells.

To re-mark the CLP flag value of ATM cells:

Step

Command

Remarks

1. Enter system view.

system-view

N/A

2. Create a traffic class and enter its view.

traffic classifier classifier-name [ operator { and | or } ]

N/A

3. Configure match criteria.

if-match [ not ] match-criteria

By default, no match criteria exist.

4. Return to system view.

quit

N/A

5. Create a traffic behavior and enter its view.

traffic behavior behavior-name

By default, no traffic behaviors exist.

6. Re-mark the CLP flag value of ATM cells.

remark [ green | red | yellow ] atm-clp atm-clp-value

By default, the CLP flag value of ATM cells is not re-marked.

The CLP flag value of ATM cells is 0 or 1. The cells with a CLP flag value of 1 are dropped first when network congestion occurs.

7. Return to system view.

quit

N/A

8. Create a QoS policy and enter its view.

qos policy policy-name

N/A

9. Associate a traffic class with a traffic behavior in the QoS policy.

classifier classifier-name behavior behavior-name [ mode dcbx ]

By default, a traffic class is not associated with a traffic behavior.

10. Return to system view.

quit

N/A

11. Enter ATM interface view or ATM subinterface view.

interface atm { interface-number | interface-number.subnumber }

N/A

12. Enter PVC view or PVC view in PVC group.

  • Enter PVC view:pvc { pvc-name [ vpi/vci ] | vpi/vci }

  • Enter PVC view in PVC group:

    1. pvc-group group-number

    2. pvc { pvc-name [ vpi/vci ] | vpi/vci }

N/A

13. Apply the QoS policy to the PVC.

qos apply policy policy-name outbound

By default, no QoS policy is applied to the PVC.
