It will be marked as DSCP BE and classified into forwarding class BE.

It will be marked as DSCP NC1 and classified into forwarding class BE.

It will be marked as DSCP NC1 and classified into forwarding class NC.

It will be marked as DSCP NC1 and classified into forwarding class AF.

Multi-field classification can use both MAC criteria and IP criteria in the same SAP-ingress QoS policy.

Behavior aggregate classification can use both lsp-exp and dscp in the same SAP-ingress QoS policy.

Multi-field classification cannot use both IP criteria and IPv6 criteria in the same SAP-ingress QoS policy.

Behavior aggregate classification cannot use both dot1p and lsp-exp in the same SAP-ingress QoS policy.

weighted fair queues (WFQ)

On all ports on the Nokia 7750 SR.

At the junction of high-speed to low-speed links or at places of traffic aggregation.

At the junction of low-speed to high-speed links or at places of traffic aggregation.

On low-speed WAN links.

Nowhere. Shaping is only performed in hardware and serviced in a round-robin.

On the network egress port.

On the SDP.

On the access ingress port.

On the egress MDA.

On the SAP.

On the ingress MDA.

It will be stored in the reserved buffer space and remain out-of-profile.

It will be stored in the reserved buffer space and become in-profile.

It will contend for shared buffer space with packets from other queues.

It will be discarded because the high-priority-only threshold has been reached.

Queue parameters with which the queue will compete for bandwidth.

The level of hierarchy with which a group of schedulers is associated.

Bandwidth controls that limit each child scheduler or child queues associated with the scheduler.

The maximum bandwidth that the parent scheduler can offer its child queues or schedulers.

The policy should be placed in a " shutdown " state before changes are made.

A new network policy should be created and applied to the interface, overwriting the previous policy.

The policy must first be removed from the interface, then modified and re-applied to the interface.

Before the policy can be changed, it must be deleted with the no network qos < policy-id > command.

Before any changes are made to the policy, all network interfaces where the policy is applied have to be shut down.

A packet is accepted into a queue based on its priority and forwarding class.

Buffer admission control limits the number of out-of-profile packets that enter the queue.

Both high priority-only buffer space and WRED can be used in a queue.

Priority is used when a packet enters a SAP-ingress queue.

Queue 5 is using priority mode.

UDP traffic can be serviced at a maximum rate of 20 Mbps.

Ping traffic is place in queue 5.

Queues 5 and 6 will receive equal portions of any remaining available bandwidth to meet their above-CIR bandwidth requirements.

Queue 3 is scheduled before queue 5.
