Use the DiffServ policy commands to specify traffic conditioning actions, such as policing and marking, to apply to traffic classes.
Use the policy commands to associate a traffic class that you define by using the class command set with one or more QoS policy attributes. Assign the class/policy association to an interface to form a service. Specify the policy name when you create the policy.
Each traffic class defines a particular treatment for packets that match the class definition. You can associate multiple traffic classes with a single policy. When a packet satisfies the conditions of more than one class, preference is based on the order in which you add the classes to the policy. The first class you add has the highest precedence.
This set of commands consists of policy creation/deletion, class addition/removal, and individual policy attributes.
NOTE: The only way to remove an individual policy attribute from a class instance within a policy is to remove the class instance and re-add it to the policy. The values associated with an existing policy attribute can be changed without removing the class instance.
The CLI command root is policy-map.
This command establishes a new DiffServ policy. The <policyname> parameter is a casesensitive alphanumeric string from 1 to 31 characters uniquely identifying the policy. The type of policy is specific to the inbound traffic direction as indicated by the in parameter.
NOTE: The CLI mode is changed to Policy-Map Config when this command is successfully executed.
This command eliminates an existing DiffServ policy. The <policyname> parameter is the name of an existing DiffServ policy. This command may be issued at any time. If the policy is currently referenced by one or more interface service attachments, this delete attempt fails.
This command changes the name of a DiffServ policy. The <policyname> is the name of an existing DiffServ class. The <newpolicyname> parameter is a case-sensitive alphanumeric string from 1 to 31 characters uniquely identifying the policy.
This command creates an instance of a class definition within the specified policy for the purpose of defining treatment of the traffic class through subsequent policy attribute statements. The <classname> is the name of an existing DiffServ class.
NOTE 1: This command causes the specified policy to create a reference to the class definition.
NOTE 2: The CLI mode is changed to Policy-Class-Map Config when this command is successfully executed.
This command deletes the instance of a particular class and its defined treatment from the specified policy. <classname> is the names of an existing DiffServ class.
NOTE: This command removes the reference to the class definition for the specified policy.
This command modifies the queue id to which the associated traffic stream is assigned. The queueid is an integer from 0 to n-1, where n is the number of egress queues supported by the device.
This command specifies that all packets for the associated traffic stream are to be dropped at ingress.
This command specifies that all incoming packets for the associated traffic stream are copied to a specific egress interface (physical port or LAG).
NOTE: This command is not available on the Tejas Networks 5630x platform.
This command specifies that all incoming packets for the associated traffic stream are redirected to a specific egress interface (physical port or port-channel) and the redirected port should be part of the VLAN.
Use this command to enable color-aware traffic policing and define the conform-color class map. Used in conjunction with the police command where the fields for the conform level are specified. The class-map name parameter is the name of an existing DiffServ class map.
NOTE: This command may only be used after specifying a police command for the policy-class instance.
This command marks all packets for the associated traffic stream with the specified class of service value in the priority field of the 802.1p header (the only tag in a single tagged packet or the first or outer 802.1Q tag of a double VLAN tagged packet). If the packet does not already contain this header, one is inserted. The CoS value is an integer from 0 to 7.
This command marks outer VLAN tag priority bits of all packets as the inner VLAN tag priority, marking Cos as Secondary CoS. This essentially means that the inner VLAN tag CoS is copied to the outer VLAN tag CoS.
This command marks all packets for the associated traffic stream with the specified IP DSCP value. The dscpval value is specified as either an integer from 0 to 63, or symbolically through one of the following keywords: af11, af12, af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, be, cs0, cs1, cs2, cs3, cs4, cs5, cs6, cs7, ef.
This command marks all packets for the associated traffic stream with the specified IP Precedence value. The IP Precedence value is an integer from 0 to 7.
This command is used to establish the traffic policing style for the specified class. The simple form of the police command uses a single data rate and burst size, resulting in two outcomes: conform and violate. The conforming data rate is specified in kilobits-per-second (Kbps) and is an integer from 1 to 4294967295. The conforming burst size is specified in kilobytes (KB) and is an integer from 1 to 128.
For each outcome, the only possible actions are drop, set-dscp-transmit, set-prec-transmit, set-cos-as-sec-cos, set-cos-as-sec-cos and set-cos-transmit. In this simple form of the police command, the conform action defaults to transmit and the violate action defaults to drop. For set-dscp-transmit, a <dscpval> value is required and is specified as either an integer from 0 to 63, or symbolically through one of the following keywords: af11, af12, af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, be, cs0, cs1, cs2, cs3, cs4, cs5, cs6, cs7, ef.
For set-prec-transmit, an IP Precedence value is required and is specified as an integer from 0-7.
This command is the two-rate form of the police command and is used to establish the traffic policing style for the specified class. For each outcome, the only possible actions are drop, set-cos-as-sec-cos, set-cos-transmit, set-sec-cos-transmit, set-dscp-transmit, set-prec-transmit, or transmit. In this two-rate form of the police command, the conform action defaults to send, the exceed action defaults to drop, and the violate action defaults to drop. These actions can be set with this command once the style has been configured.
