NOTE
Two types of priorities are available for IP packets: IP precedence and DSCP. The IP preference
value ranges from 0 to 7, and the DSCP value ranges from 0 to 63. If no default PVC is specified,
all the priorities need to be configured for PVCs in a PVC group. Only one type of priority
(either the IP precedence or DSCP) can be configured for PVCs in a PVC group.
– If some priorities in the PVC group are not configured for PVCs in the PVC group,
reconfigure priorities for PVCs.
– If all the priorities have been configured for PVCs in the PVC group, go to step 3.
3. Collect the following information and contact Huawei technical support personnel.
