frames, meaning that only the IEEE 802.1D priority level is significant
and the default PVID of the ingress port is used instead.
◆ DSCP Value – The DSCP value to be used to provide Diffserv node
behavior for the specified application type. This field may contain one of
64 code point values (0-63). A value of 0 represents use of the default
