Information About Queuing and Scheduling

On an F-Series module, a queuing policy is closely coupled with the network qos policy. 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. In the egress direction, there are four physical queues for qos policy templates on Cisco Nexus 7000
Series devices, except on the Cisco Nexus 7710 switch and Cisco Nexus 7718 switch, where, beginning with
Cisco Release 6.2(2), there is support for eight physical queues.
The system queuing policy applied by default can be overridden on a per-port basis. In general, the
user-configured queuing policies are per virtual device context (VDC).
Ingress queuing determines the following attributes:
