Service SAP QoS Policy Command Reference
The no form of the command removes the explicit IP precedence classification rule from the SAP
ingress policy. Removing the rule on the policy immediately removes the rule on all ingress SAPs
using the policy.
Parameters
ip-prec-value — The ip-prec-value is a required parameter that specifies the unique IP header ToS
fc fc-name — The value given for the fc-name parameter must be one of the predefined
priority — The priority parameter overrides the default enqueuing priority for all packets
high — This parameter is used in conjunction with the priority parameter. Setting the enqueuing

byte precedence bits value that will match the IP precedence rule. If the command is executed
more than once with the same ip-prec-value, the previous forwarding class and enqueuing
priority is completely overridden by the new parameters or defined to be inherited when a
forwarding class or enqueuing priority parameter is missing.
A maximum of eight IP precedence rules are allowed on a single policy.
The precedence is evaluated from the lowest to highest value.
Values
0 to 7
forwarding classes in the system. Specifying the fc-name is optional. When a packet matches
the rule the forwarding class is only overridden when the fc fc-name parameter is defined on
the rule. If the packet matches and the forwarding class is not explicitly defined in the rule,
the forwarding class is inherited based on previous rule matches.
The sub-class-name parameter is optional and used with the fc-name parameter to define a
preexisting sub-class. The fc-name and sub-class-name parameters must be separated by a
period (dot). If sub-class-name does not exist in the context of fc -name, an error will occur.
If sub-class-name is removed using the no fc fc-name.sub-class-name force command, the
default-fc command will automatically drop the sub-class-name and only use fc-name (the
parent forwarding class for the sub-class) as the forwarding class.
Values
fc:
class[.sub-class]

Inherit (When fc is not defined, the rule preserves the previous
forwarding class of the packet.)
received on an ingress SAP using this policy that match this rule. Specifying the priority is
optional. When a packet matches the rule the enqueuing priority is only overridden when the
priority parameter is defined on the rule. If the packet matches and priority is not explicitly
defined in the rule, the enqueuing priority is inherited based on previous rule matches.
parameter to high for a packet increases the likelihood of enqueuing the packet when the
ingress queue is congested. Ingress enqueuing priority only affects ingress SAP queuing.
When the packet is placed in a buffer on the ingress queue, the significance of the enqueuing
priority is lost.
