Supported on all 7210 SAS platforms as described in this document
This command defines the mapping of the IP DSCP value in the IP header of the received packet to the forwarding class (FC) and ingress profile.
A DSCP classification policy with IP precedence can be configured only in a service egress policy and used only with access SAP egress.
The no form of this command removes the definition of the DSCP classification policy. The no form of the policy cannot be executed if the policy is in use; for example, if the policy is associated with a network QoS policy.
dscp-classification 1
Specifies the DSCP classification policy.
Keyword to configure the software to use IP precedence entries specified in the DSCP classification policy. If this keyword is not specified, the software uses DSCP classification entries. To maintain backward compatibility, use-ip-prec-classification is not configured by default.
This keyword is only supported on the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C.
Keyword to create the DSCP classification policy.

This command creates a text description stored in the configuration file for a configuration context.
The description command associates a text string with a configuration context to help identify the context in the configuration file.
The no form of this command removes any description string from the context.
Specifies a text string describing the entity. Allowed values are any string up to 80 characters composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, and so on), the entire string must be enclosed within double quotes.

config>qos>dscp-classification
Supported on all 7210 SAS platforms as described in this document
This command maps the IP DSCP value to an FC and assigns the ingress profile to the packet. The configured value is used to match the value in the received packet and assign the configured FC and profile on a exact match.
The no form of this command removes the mapping of the IP DSCP value to the FC.
A default FC is not assigned on executing the no form. The default FC is assigned in the QoS policy with which this policy is associated with.
Specifies the IP DSCP value to match by configuring the IP DSCP name corresponding to the DSCP value.
Specifies a case-sensitive, system-defined FC name.
Specifies whether the packets assigned to this FC are considered in or out of profile. A value of in defines the packet profile as in-profile and a value of out defines the packet profile to be out-of-profile.

7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
This command defines a specific IP precedence value that must be matched to perform the associated reclassification actions. If an egress packet on the SAP matches the specified IP precedence value, the FC or profile may be overridden. By default, the FC and profile of the packet are derived from ingress classification and profiling functions.
The IP precedence bits used to match against precedence reclassification rules come from the Type of Service (ToS) field within the IPv4 header. If the packet does not have an IPv4 header, precedence-based matching is not performed.
The reclassification actions from an IP precedence reclassification rule may be overridden by a DSCP matching event.
The fc keyword is optional. When specified, the egress classification rule overwrites the FC derived from ingress. The new FC is used for egress remarking and queue mapping decisions. If a DSCP match occurs after the IP precedence match, the new FC may be overridden by the higher priority match actions. If the higher priority match actions do not specify a new FC, the FC from the IP precedence match is used.
The profile keyword is optional. When specified, the egress classification rule overwrites the profile of the packet derived from ingress. The new profile value is used for egress remarking and queue congestion behavior. If a DSCP match occurs after the IP precedence match, the new profile may be overridden by the higher priority match actions. If the higher priority match actions do not specify a new profile, the profile from the IP precedence match is used.
The no form of this command removes the reclassification rule from the SAP egress QoS policy.
Specifies the IP precedence value.
Specifies that packets matching the IP precedence value are explicitly reclassified to the specified FC regardless of the ingress classification decision. The explicit FC reclassification may be overwritten by a higher priority DSCP reclassification match. The FC name defined must be one of the eight FCs supported by the system. To remove the FC reclassification action for the specified precedence value, the prec command must be re-executed without the fc-name parameter defined.
Optional keyword to specify that packets matching the IP precedence value are explicitly reclassified to the specified profile regardless of the ingress profiling decision. The explicit profile reclassification may be overwritten by a higher priority DSCP reclassification match. To remove the profile reclassification action for the specified precedence value, the prec command must be re-executed without the profile parameter defined.
Keyword to specify that any packets matching the reclassification rule are treated as in-profile by the egress forwarding plane.
Keyword to specify that any packets matching the reclassification rule are treated as out-of-profile by the egress forwarding plane.

This command defines the map of the dot1p value in the Ethernet header of the received frame to the FC and ingress profile.
The no form of this command removes the definition of the policy. The no form of the policy cannot be executed if the policy is in use; for example, if the policy is associated with a network QoS policy.

no dot1p dot1p-priority

Supported on all 7210 SAS platforms as described in this document
This command maps the dot1p value to an FC and assigns the ingress profile to the packet. The configured value is used to match the value in the received packet and assign the configured FC and profile on a exact match.
The no form of this command removes the mapping of the dot1p value to FC.
A default FC is not assigned on executing the no form of this command. The default FC is assigned in the QoS policy with which this policy is associated with.
Specifies a case-sensitive, system-defined FC name.
Specifies whether the packets assigned to this FC are considered in or out of profile. A value of in defines the packet profile as in-profile and a value of out defines the packet profile to be out-of-profile.
