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

Network QoS Policies

Network QoS policies define ingress forwarding class meters and maps traffic to those meters for
access uplink ports. When a network QoS policy is created, it always has two meters defined that
cannot be deleted, one for the all unicast traffic and one for all multipoint traffic. These meters
exist within the definition of the policy. The meters only get instantiated in hardware when the
policy is applied to a access uplink port. It also defines the forwarding class to priority bit marking,
on the egress.
A network QoS policy defines both the ingress and egress handling of QoS on the access uplink
ports. The following functions are defined:
•
•
The required elements to be defined in a network QoS policy are:
•
•
•
•
•
Optional network QoS policy elements include:
•
•
•
Network policy ID 1 is reserved as the default network QoS policy. The default policy cannot be
deleted or changed.
The default network QoS policy is applied to all access uplink ports which do not have another
network QoS policy explicitly assigned.
The network QoS policy applied at network egress (for example, on an access uplink port)
determines how or if the profile state is marked in packets transmitted into the service core
