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 an ingress IP interface that is bound to a VPRN, the policy
becomes associated with every SAP on the VPRN and augments the QoS policy that is defined on
each SAP. Packets that are bridged will be processed using the policy defined on the VPRN 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 IP interface that has been bound to a VPRN, the
policy becomes associated with every SAP on the VPRN and augments the egress QoS policy that is
defined on each SAP. Packets that are bridged will be processed using the policy defined on the
VPRN SAP; packets that are routed will be processed using the policy defined in the IP interface-
binding context.
By default, no specific QoS policy is associated with the SAP or IP interface for ingress or egress, so
the default QoS policy is used.
