Does the default queue for DSCP contain CoS values?
If all DSCP values are not mapped to a nondefault ingress queue, the default queue should have the CoS values associated with it. DSCP queuing is automatically disabled when the user removes all match dscp commands (using no match statements).
How are queuing policies selected for network QoS?
For each network qos policy that is activated, its corresponding default queuing policy is automatically selected for the system target. In the ingress direction, either two or four queues (buffer pools) are formed depending on the policy template.
Do I need a license to use qsqos?
QoS requires no license. Any feature not included in a license package is bundled with the Cisco NX-OS system images and is provided at no extra charge to you. For a complete explanation of the NX-OS licensing scheme, see the Cisco Nexus 7000 Series NX-OS Licensing Guide, Release 4.2. However, using VDCs requires an Advanced Services license.
