queue-frame-based-accounting — This keyword enables frame based accounting on all queues
associated with the SAP or Multi-Service Site. If frame based accounting is required when an
aggregate limit is not necessary, the max keyword should precede the queue-frame-based-accounting
keyword. If frame based accounting must be disabled, execute agg-rate-limit without the queue-
frame-based-accounting keyword present.
Default Frame based accounting is disabled by default
qinq-mark-top-only

Context config>service>ies>if>sap>egress

Description When enabled (the encapsulation type of the access port where this SAP is defined as qinq), the qinq-
mark-top-only command specifies which P-bits to mark during packet egress. When disabled, both
set of P-bits are marked. When the enabled, only the P-bits in the top Q-tag are marked.
Default no qinq-mark-top-only

Description Associates a Quality of Service (QoS) policy with an ingress or egress Service Access Point (SAP) or
IP interface.
QoS ingress and egress policies are important for the enforcement of SLA agreements. The policy ID
must be defined prior to associating the policy with a SAP or IP interface. If the policy-id does not
exist, an error will be returned.
The qos command is used to associate both ingress and egress QoS policies. The qos command only
allows ingress policies to be associated on SAP or IP interface ingress and egress policies on SAP or
IP interface egress. Attempts to associate a QoS policy of the wrong type returns an error.
Only one ingress and one egress QoS policy can be associated with a SAP or IP interface at one time.
Attempts to associate a second QoS policy of a given type will return an error.
When an ingress QoS policy is defined on IES ingress IP interface that is bound to a VPLS, the policy
becomes associated with every SAP on the VPLS and augments the QoS policy that is defined on
each SAP. Packets that are bridged will be processed using the policy defined on the VPLS SAP;
packets that are routed will be processed using the policy defined in the IES IP interface-binding
context.
When an egress QoS policy is associated with an IES IP interface that has been bound to a VPLS, the
