Page 20: Qos Overview
The 7210 SAS M has extensive and flexible capabilities to classify, police, shape, and mark traffic. In the Alcatel-Lucent service router’s service model, a service is provisioned on the provider-edge (PE) equipment. Service data is encapsulated and then sent in a service tunnel to the far-end Alcatel-Lucent service router where the service data is delivered.
Page 21: Qos Policies
The FCs are mapped onto the queues. There are 8 queues at the port level. FC-to-queue mapping is static and is not configurable. The number of queues are static 7210 SAS M OS Quality of Service Guide Page 21...
Page 22 A network QoS policy defines both ingress and egress behavior. One network queue policy can be applied to the network port or a access-uplink port. If no QoS policy is explicitly applied to a SAP, port or interface, a default QoS policy is applied. Page 22 7210 SAS M OS Quality of Service Guide...

In the default policy, only meter “1” is defined. All FC and all traffic types use meter “1” by default. Meter “11” is not created by default and is not available for use. Sample configuration: *7210-SAS>config>qos# sap-ingress 1 create // Default policy 7210 SAS M OS Quality of Service Guide Page 233...
Page 210 If a FC is created with an explicit unicast meter, an explicit broadcast meter, an explicit unknown-unicast meter, and an explicit multicast meter, use these meters for unicast, broadcast, unknown-unicast and multicast traffic types respectively. Page 234 7210 SAS M OS Quality of Service Guide...
Page 211 A multipoint meter cannot be used. A multipoint meter configured in a policy is not used when the policy is applied to a SAP in an Epipe service. • All FCs associated with a meter always use the unicast meter. 7210 SAS M OS Quality of Service Guide Page 235...

Page 217 Taking into account the number of match criteria and the number of FCs used, use the equation given below to arrive at total number of classification entries per policy, for example: TC=Σ E(i)* C(i) i=nc,h1,ef,h2,l1,af,l2,be 7210 SAS M OS Quality of Service Guide Page 241...
