Which of the following are entities of the Nokia 7750 SR on which you can NOT apply a network- queue policy? (Choose three)

A network-queue policy is a QoS object that can be bound only to

• the ingress side of an MDA and

• the egress side of an Ethernet network port.

Router interfaces build their queues from “queue-group” templates, and service SAPs use SAP-ingress / SAP-egress queue policies.

Because a network-queue policy is not accepted on router interfaces, on SAPs, or on the ingress direction of a network port, the three entities listed above cannot have such a policy attached.

B. Ingress MDA – CLI command card mda ingress-qos network-queue permits binding.

D. Egress Ethernet network ports – CLI command port ethernet network qos network-queue permits binding.

1. Nokia SR OS 22.5.R1 Quality of Service Guide, “Network Queue Policies”, pp. 193-198: “A network-queue policy can be applied to the ingress side of an MDA and to the egress side of a network (Ethernet) port.”

2. Nokia SR OS 22.5.R1 Interface Configuration Guide, §4.3 “Router-Interface QoS”, p. 145: router interfaces accept queue-groups, not network-queue policies.

3. Nokia SR OS 22.5.R1 Service Configuration Guide, §7.2 “SAP QoS Overview”, p. 321: SAPs are associated with SAP-ingress and SAP-egress queue policies, not network-queue policies.

4. Nokia SR OS 22.5.R1 Command Reference, “port ethernet network qos network-queue”, p. 612: shows binding of a network-queue policy only at egress port level.
