traffic behavior view
Set the cell loss priority (CLP) bit
for ATM cells
Quit to system view
Create a policy and enter policy
view
Associate the class with the traffic
behavior in the policy
Quit to system view
Enter ATM interface or
subinterface view

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.
Follow these steps to assign a transmission priority to an ATM PVC:
To do...
Enter system view
Enter ATM subinterface view
Create a PVC and enter PVC view
Use the command...
system-view
traffic classifier tcl-name
[ operator { and | or } ]
if-match [ not ] match-criteria
quit
traffic behavior behavior-name
remark atm-clp atm-clp-value
quit
qos policy policy-name
classifier tcl-name behavior
behavior-name
quit
interface atm { interface-number |
interface-number.subnumber }
pvc { pvc-name [ vpi/vci ] | vpi/vci }
qos apply policy policy-name
{ inbound | outbound }
Use the command...
system-view
interface atm { interface-number |
interface-number.subnumber }
pvc { pvc-name [ vpi/vci ] | vpi/vci }
