Basic Configurations
A basic network QoS policy must conform to the following:
• Each network QoS policy must have a unique policy ID.
• Specify the default-action.
• Have a QoS policy scope of template or exclusive.
• Based on the 7210 SAS platform being used, have at least one default unicast forwarding
class meter/queue.
• Based on the 7210 SAS platform being used, have at least one multipoint forwarding class
meter/queue.
Create a Network QoS Policy
Configuring and applying QoS policies other than the default policy is optional. A default network
policy of the appropriate typeis applied to each uplink port.
To create an network QoS policy , define the following:
• A network policy ID value. The system will not dynamically assign a value.
• Include a description. The description provides a brief overview of policy features.
• Egress Marking/ remarking - Specifies the egress FC to marking value (for example: IEEE
802.1p, etc) map. Otherwise, the default values are applied.
→ Remarking — If enabled, this command remarks ALL packets that egress on the
specified access uplink port. The remarking is based on the forwarding class to
marking values mapping defined under the egress node of the network QoS policy.
For 7210 SAS-E, remarking is always enabled. In other words, user cannot choose to
disable it. On 7210 SAS-D and 7210 SAS-K, user has an option to enable it or disable
it.
→ Forwarding class criteria — The forwarding class name represents an egress queue.
Specify forwarding class criteria to define the marking criteria of packets flowing
through it.
→ Marking Value— The marking (for example: IEEE 802.1p) value is used for all
packets requiring marking that egress on this forwarding class queue that are in or out
of profile.
• Ingress criteria — Specifies the criteria to use for forwarding class mapping for all
packets.
