If the QoS mapping mode is set to DSCP with this command, and the
◆
ingress packet type is IPv4, then priority processing will be based on
the DSCP value in the ingress packet.
If the QoS mapping mode is set to DSCP, and a non-IP packet is
◆
received, the packet's CoS and CFI (Canonical Format Indicator) values
are used for priority processing if the packet is tagged. For an untagged
packet, the default port priority (see
processing.
If the QoS mapping mode is set to CoS with this command, and the
