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

page 820

) is used for priority

processing.

If the QoS mapping mode is set to CoS with this command, and the

ingress packet type is IPv4, then priority processing will be based on

the CoS and CFI values in the ingress packet.

For an untagged packet, the default port priority (see

page 820

) is used

for priority processing.

XAMPLE

This example sets the QoS priority mapping mode to use DSCP based on

the conditions described in the Command Usage section.
