Access Egress Qos Policies - Alcatel-Lucent 7210 SAS E OS Quality Of Service Manual

Access Egress QoS Policies

An access egress policy defines the queue and marking characteristics for the traffic egressing
towards the customer on the access ports. There are 8 queues always available at the access port
and FCs are mapped into these 8 Queues. By configuring appropriate queue shape rates the
individual FC traffic can be managed so that each FC traffic is well within SLA limits and does not
impact the serviceability of other FCs.
Access egress QoS policies define access queues and map forwarding class flows to queues. There
are 8 queues always available per access port and all forwarding classes traffic is mapped into
these separate 8 queue as per
a basic access egress QoS policy, the following are required:
•
•
•
•
Each queue in a policy is associated with one forwarding class. Each queue can have its individual
queue parameters allowing individual rate shaping of the forwarding class mapped to the queue.
The forwarding class determination per service egress packet is determined at ingress. If the
packet ingressed the service on the same router, the service ingress classification rules determine
the forwarding class of the packet. If the packet was received over a service transport tunnel
network port, the forwarding class is marked in the outer tag of the QinQ encapsulation.
Access egress QoS policy ID 1 is reserved as the default access egress policy. The default policy
cannot be deleted or changed.
The default access egress policy is applied to all access ports which do not have another access
egress policy explicitly assigned. The characteristics of the default policy are listed in the
following table.

IEEE 802.1p priority value remarking based on forwarding class.
All customer traffic containing IEEE 802.1p encapsulation will be marked according to
the default FC-Dot1p marking map if Dot1p values are not explicitly configured.
