Command Reference
Description Note that:
■ If you do not configure the ip-dscp command, IP packets of all priorities are
carried by the fundamental PVC of the PVC group, that is, the PVC used to
construct the PVC group.
■ If you configure the ip-dscp command with the default keyword, IP packets of
the definitely specified priority levels are carried by the specified PVC, while IP
packets of priority levels that are not specified are carried by the PVC specified
with the default keyword. If no PVC is specified by the
ip-dscp command with
the default keyword, those IP packets of priority levels that are not specified are
carried by the fundamental PVC.
■ The specified PVC must be in the current PVC group, and the lowest priority level
(
min) must be less than or equal to the highest priority level (max).
■ PVC service mapping does not change the priority of an IP packet. To change the
priority of an IP packet, you can configure CAR.
