    The 7210 SAS E 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 routerwhere the service data is delivered.

    Overview Overview Egress port rate limiting allows the device to limit the traffic that egresses through a port to a value less than the available link bandwidth. This feature is supported on the 7210 SAS-Series platforms. Applications This feature is useful when connecting the 7210 SAS to an Ethernet-over-SDH (EoSDH) (or microwave) network, where the network allocates predetermined bandwidth to the nodes connecting into it, based on the transport bandwidth requirement.

Typically, the IFG and preamble constitutes about 12 + 8 = 20 bytes. The overhead for Ethernet ports uses this value. A configurable CLI command enables accounting of the frame overhead at ingress or egress.

    Frame Based Accounting Basic Configurations To enable frame-based accounting, you must perform the following: • The frame-based-accounting command is in the *A:Dut-1> config>qos>frame-based- accounting context. • The ingress-enable command enables frame-based-accounting for ingress metering. • The egress-enable command enables frame-based-accounting for egress queue rates, scheduler and port level egress-rate.

  • Page 78: Overview

    Overview Overview The ingress component of the policy defines how Dot1p bits are mapped to internal forwarding class and profile state. The forwarding class and profile state define the Per Hop Behavior (PHB) or the QoS treatment through the 7210 SAS. The mapping on each access uplink port defaults to the mappings defined in the default network QoS policy until an explicit policy is defined for the access uplink ports.
  • Page 79: Normal Qos Operation

    Network QoS Policies Normal QoS Operation The following types of QoS mapping decisions are applicable on a network ingress IP interface • Ethernet Dot1P value mapping (if defined) • Default QoS mapping The default QoS mapping always exists on an ingress access uplink port and every received packet will be mapped to this default if another explicitly defined matching entry does not exist.

  • Page 98 QoS Commands dot1p Syntax dot1p dot1p-priority fc fc-name profile {in | out} no dot1p dot1p-priority Context config>qos>network>ingress Description This command explicitly sets the forwarding class or enqueuing priorityand profile of the packet when a packet is marked with a dot1p-priority specified. Adding a dot1p rule on the policy forces packets that match the dot1p-priority specified to be assigned to the forwarding class and profile of the packet based on the parameters included in the Dot1p rule.

  • Page 100 QoS Commands meter Syntax meter meter-id no meter Context config>qos>network>ingress>fc Description This command overrides the default unicast forwarding type meter mapping for fc fc-name. The spec- ified meter-id must exist within the policy as a non-multipoint meter before the mapping can be made. Once the forwarding class mapping is executed, all unicast traffic on a port using this policy is for- warded using the meter-id.

For the CIR and PIR parameters, individually the system attempts to find the best operational rate depending on the defined constraint.
  • Page 102 QoS Commands ets are marked as in-profile by the meter to indicate that the traffic is complying meter configured parameters.

  • Page 103 QoS Commands Default trtcm Parameters trtcm — Meters the packet stream and marks the packets either green, yellow, or red. A packet is marked red if it exceeds the PIR. Otherwise, it is marked either yellow or green depending on whether it exceeds or doesn't exceed the CIR.

Since the 7210 SAS E will be used to con- nect to a particular diffserv domain so it is very important that each and every packet ingressing on the 7210 SAS E is mapped and marked and thereby assigned to a particular diffserv class while going through the network.

    Overview Overview Configuring Port Scheduler Policies The port-scheduler-policy command creates a port scheduler template which may be assigned to an egress port. Only one port scheduler policy is allowed per port. There is a “default” port- scheduler policy (which services the queues of the port in a Strict order) associated with each port. To change the behavior, users can associate the port with another port-scheduler policy.
