The CoS bits in the Because the QoS treatment is inferred from the EXP both class and drop precedence , several classes of traffic can be multiplexed onto a single LSP use the same label. The maximum number of classes would be less after reserving some values for control plane traffic or if some of the classes have a drop precedence associated with them.
A DSCP defines a class and drop precedence. In some cases, however, the EXP bits are used exclusively to encode the dropping precedence. Layer 2 frames carry Layer 3 packets. A Layer 2 CoS label can have a value ranging between zero for low priority and seven for high priority.
A Layer 3 IP precedence label can have a value ranging between zero for low priority and seven for high priority. IP precedence values are defined by the three most significant bits of the 1-byte ToS byte. Marking is also the process of choosing different values for the MPLS EXP field to mark packets so that they have the priority that they require during periods of congestion. Policing can mark or drop traffic. Setting the MPLS experimental EXP field value satisfies the requirement of service providers who do not want the value of the IP precedence field modified within IP packets transported through their networks.
By choosing different values for the MPLS EXP field, you can mark packets so that packets have the priority that they require during periods of congestion. None of the following have any effect on MPLS packets:. Classification is the process that selects the traffic to be marked. Classification accomplishes this by partitioning traffic into multiple priority levels, or classes of service. Traffic classification is the primary component of class-based QoS provisioning.
Policing causes traffic that exceeds the configured rate to be discarded or marked down to a higher drop precedence. Marking is a way to identify packet flows to differentiate them. Packet marking allows you to partition your network into multiple priority levels or classes of service. The MPLS QoS policing and marking features that you can implement depend on the received traffic type and the forwarding operation applied to the traffic.
See "Configuring a Policy Map" section for information. You do not need to enter a command to save the IP ToS. You can attach egress EXP mutation maps to these interface types:. Tunneling provides QoS transparency from one edge of a network to the other edge of the network. Differentiated service satisfies a range of requirements by supplying for each transmitted packet the service specified for that packet by its QoS. Service can be specified in different ways, for example, using the IP precedence bit settings in IP packets.
Based on the IP precedence marking, the packet is given the treatment configured for that quality of service. However, the service provider might want to set QoS for an MPLS packet to a different value determined by the service offering. The ingress interfaces are physical ports, subinterfaces, or VLANs. The results of ingress and egress aggregate and microflow policing are combined into a final policing decision.
The out-of-profile packets can be either dropped or marked down in the DSCP. Note Incoming labels are aggregate or nonaggregate. The nonaggregate label indicates that the packet contains the IP next hop information. The PFC receives the traffic from the input interface and uses the For classification of incoming IP packets, the input service policy can also use access control lists ACLs. For each incoming packet, the PFC performs a lookup on the IP address to determine the next-hop router.
The PFC forwards the labeled packets to the appropriate output interface for processing. The PFC also forwards the At the output interface, the labeled packets are differentiated by class for marking or policing. Incoming MPLS-labeled packets and The PFC receives the traffic from the input interface and uses the EXP bits to perform classification, marking, and policing.
Note Within the service provider network, there is no IP precedence field for the queueing algorithm to use because the packets are MPLS packets. MPLS-labeled packets and Aggregate labels are classified using the original Nonaggregate labels are classified with the EXP value by default.
For aggregate labels, the PFC performs a lookup on the IP address to determine the packet's destination; the PFC then forwards the packet to the appropriate output interface for processing. For non-aggregate labels, forwarding is based on the label.
By default, non-aggregate labels are popped at the penultimate-hop router next to last , not the egress PE router. The packets are differentiated according to the Additionally, this section provides information about the capabilities provided by the ingress and egress interface modules. Egress policies do not classify traffic on the imposed EXP value nor on a marking done by an ingress policy.
If more than one label is imposed, the EXP value is the same in each label. See the following two examples:. The CoS is mapped from the ToS. LAN port classification is based on the received Layer 2 Additionally, this section provides information about the capabilities provided by the ingress and egress modules. The QoS result is affected by the following:. The egress IP policy can overwrite this ingress ToS to an arbitrary value.
Note For information about recirculation, see the "Recirculation" section. Ingress IP policies are not supported. The match mpls experimental command matches on the EXP value in the received topmost label. In situations when there are multiple interfaces belonging to the same VPN, you can perform per-VPN policing aggregation using the same shared policer in the ingress or egress service policies for all similar interfaces associated with the same PFC. Note For information on recirculation, see the "Recirculation" section.
Additionally, the section provides information about the capabilities provided by the ingress and egress modules. What the PFC does next depends on whether it is swapping labels, imposing a new label, or popping a label:. The PFC can mark down out-of-profile traffic using the police command's exceed and violate actions.
It does not mark in-profile traffic, so the conform action must be transmitted and the set command cannot be used. It then copies the EXP value in the imposed label to the underlying swapped label. The PFC can mark in-profile and mark down out-of-profile traffic. The match mpls experimental command matches on the egress CoS; it does not match on the EXP in the topmost label. Note If there is a service policy with a set for EXP field, its EXP field will be placed into the imposed label and also into the swapped label.
The default platform qos rewrite ip dscp command must remain enabled in order for the PFC to assign the correct EXP value for the labels that it imposes. Note The switch applies the port CoS value to untagged ingress traffic and to traffic that is received through ports that cannot be configured to trust CoS.
This allows you to define service policies to police the EXP traffic on a per-interface basis by using the police command. To configure a class map, perform this task beginning in global configuration mode:. This example shows that all packets that contain MPLS experimental value 3 are matched by the traffic class named exp After you identify the class, you can use the match mpls experimental command to configure its match criteria.
The last command overrides the previously entered commands. You can attach only one policy map to an interface. Policy maps can contain one or more policy map classes, each with different policy map commands. Configure a separate policy map class in the policy map for each type of traffic that an interface receives. Put all commands for each type of traffic in the same policy map class. To disable the setting, use the no form of this command. Note The set mpls experimental imposition command replaces the set mpls experimental command.
When setting the EXP value on all imposed labels, follow these guidelines and restrictions:. Policing is a function in the PFC hardware that provides the ability to rate limit a particular traffic class to a specific rate. The PFC supports aggregate policing and microflow policing. Aggregate policing meters all traffic that ingresses into a port, regardless of different source, destination, protocol, source port, or destination port.
Microflow policing meters all traffic that ingresses into a port, on a per flow per source, destination, protocol, source port, and destination port. For additional information on aggregate and microflow policing, see Chapter 61 "Classification, Marking, and Policing.
The following restrictions and guidelines apply when using the police command to configure a policy map:. The packet may get dropped or the EXP value is marked down. The PFC does not mark in-profile traffic; when marking down out-of-profile traffic, the PFC marks the outgoing topmost label.
The PFC does not propagate the marking down through the label stack. Otherwise, flow key operation is similar to IP-to-IP. You can display a policy map with an interface summary for MPLS QoS classes or with the configuration of all classes configured for all service policies on the specified interface.
To display the configuration of all classes configured for all service policies on the specified interface, perform this task:. Displays the configuration of all classes configured for all policy maps on the specified interface. Router config-if platform qos exp-mutation exp-mutation-table-name. Router config platform qos map exp-dscp values. Valid values are 0 through Valid values are 0 through 7.
Tunneling provides QoS the ability to be transparent from one edge of a network to the other edge of the network. A tunnel starts where there is label imposition. EXP marking does not propagate to the packet ToS byte. For a description of this mode, see the "Short Pipe Mode" section. This mode provides consistent QoS classification and marking throughout the network including CE and core routers. EXP marking is propagated to the underlying ToS byte.
