Service Ingress QoS Policy Entry Commands
Values
Default
priority — The priority parameter overrides the default enqueuing priority for all packets received on a
SAP using this policy that match this rule. Specifying the priority (high or low) 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.
Default
high — The high parameter is used in conjunction with the priority parameter. Setting the priority
enqueuing parameter to high for a packet increases the likelihood to enqueue the packet when the queue
is congested. The enqueuing priority only affects ingress SAP queuing. When the packet is placed in a
buffer on the queue, the significance of the enqueuing priority is lost.
low — The low parameter is used in conjunction with the priority parameter. Setting the priority
enqueuing parameter to low for a packet decreases the likelihood to enqueue the packet when the queue
is congested. The 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.
Default
policer-id — A valid policer-id must be specified. The parameter policer-id references a policer-id that has
already been created within the sap-ingress QoS policy.

Description
This command defines the reclassification actions that should be performed on any packet matching the
defined IP flow criteria within the entries match node. When defined under the ip-criteria context, the
reclassification ony applies to IPv4 packets. When defined under the ipv6-criteria context, the
reclassification only applies to IPv6 packets.
If an egress packet on the SAP matches the specified IP flow entry, the forwarding class, profile accounting
behavior may be overridden. By default, the forwarding class and profile of the packet is derived from
ingress classification and profiling functions. The default behavior for HSMDA queue accounting is to use
the counters associated with the queue to which the packet is mapped. Matching an IP flow reclassification
