Access SAP Forwarding Class Based Redirection
Ingress and Egress SAP Forwarding Class Redirection Association Rules
Policy Based Provisioning Model
The association rules between SAP ingress and egress QoS policies and queue group templates are
simple since both the target queue group name and queue ID within the group are explicitly stated
within the access QoS policies.
The following association rules apply when the policy based provisioning model is applied with
port queue groups.
When a SAP ingress QoS policy forwarding class is redirected to a queue group queue ID:
•
•
•
When a SAP ingress QoS policy forwarding class redirection is removed from a queue group
queue ID:
•
•
•
When a SAP egress QoS policy forwarding class is redirected to a queue group queue ID:
•
•

If the queue group name does not exist as an ingress queue group template, the forwarding
class redirection will fail.
If a redirection queue ID does not exist within the ingress queue group template, the
forwarding class redirection will fail.
If the SAP ingress QoS policy is currently applied to a non-Ethernet port or an Ethernet
port where the specified ingress queue group does not exist, the forwarding class
redirection will fail.
If the forwarding class is being moved to another queue group queue ID that does not exist
within an ingress queue group template, the redirection removal from the current queue
group queue ID will fail.
If the forwarding class is being moved to a local queue ID within the SAP ingress QoS
policy and the local queue ID does not exist, the redirection removal from the current
queue group queue ID will fail.
If the forwarding class is being moved to a local queue ID within the SAP ingress QoS
policy and it is the first forwarding class to be mapped to the queue ID the system will
attempt to instantiate the queue on each ingress SAP where the SAP ingress QoS policy is
applied. If the queue cannot be created on any of the SAPs, the redirection removal from
the current queue group ID will fail.
If the queue group name does not exist as an egress queue group template, the forwarding
class redirection will fail.
If a redirection queue ID does not exist within the egress queue group template, the
forwarding class redirection will fail.
