If removing the SAP ingress QoS policy from the SAP results in the need to instantiate an
ingress queue for the SAP that cannot be created, the SAP ingress QoS policy removal
action will fail.
The system decrements the port queue group association counter for each egress port
queue group referenced in a forwarding class redirection within the removed SAP egress
QoS policy. The egress port queue group association counter is decremented for each
forwarding class redirected to the queue group within the removed policy.
If the queue group name does not exist as an ingress queue group template, the redirection
will fail.
If a queue group name does exist as an ingress queue group template, but the specified
instance-id has not been instantiated on the same forwarding plane as used by the SAP, the
redirection will fail.
If a redirected policer ID in the SAP ingress QoS policy does not match a policer ID in the
named ingress queue group template, the 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 instance does not exist on the forwarding
plane, the redirection will fail.
The system increments the association counter for the ingress queue group template with
the same name as the queue group specified in the SAP redirection for each forwarding
class redirected to the template.
The system increments the policer ID association counter within the queue group template
for each forwarding class redirected to a policer ID.
The system increments the forwarding plane queue group instance association counter for
each ingress queue group instance where a SAP ingress QoS policy specifying redirection
is applied to a SAP.
If the forwarding class is being moved to another queue group policer ID that does not
exist within the ingress FP queue group, the redirection removal from the current queue
group policer ID will fail.
