You can modify an egress CoS to queue map irrespective of the ingress CoS to queue map by using the match
cos command to configure the desired CoS to queue mapping.
An egress queue follows a hierarchical scheduling pattern when both drop classes are present. For more
information, see the "Ingress Queuing" section. For a given network qos template, the egress queuing
configuration (the number of DWRR queues, number of priority queues, and the scheduling hierarchy) are
fixed. You can modify the bandwidth percentage, priority level, and shaper for a given port.
You use the bandwidth command to control the bandwidth allocated to an egress queue (traffic class). For
more information about the bandwidth command, see the Cisco Nexus 7000 Series NX-OS Quality of Service
Command Reference.
Note
Bandwidth and priority are mutually exclusive on a class map (queue).
