Parameters
min: Specifies the minimum priority of IP packets carried by the PVC, in the range of 0 to 7.
max: Specifies the maximum priority of IP packets carried by the PVC, in the range of 0 to 7. The max
value must equal to or be larger than the min value.
default: Specifies the PVC as the default PVC. IP packets without transmission priorities are sent through
the default PVC.
Usage guidelines
This command is applicable to only the PVCs in a PVC-group.
If no PVC is specified as the default PVC, IP packets without transmission priorities are sent through all
PVCs that are not configured with priorities in turn.
If no PVC is specified as the default PVC and all PVCs are configured with transmission priorities, IP
packets that cannot find the PVCs with corresponding priorities are dropped.
This command cannot change the priority of an IP packet.
Examples
# Configure PVC aa with VPI/VCI value being 1/32 to carry IP packets with priorities from 0 to 3.
