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 |
