Ingress and Egress Queue Group Creation and Redirection
queue or the egress shared queue for that FC defined in the network-queue policy applied
to the egress of this port. This is the existing implementation and default behavior for a
PW packet.
the queue-group name exists but the policer-id and/or the queue-id is not defined in the
queue-group template, the association is failed at the time the user associates the egress
context of a spoke-SDP to the named queue-group. In such a case, the PW packet is fed
directly to the corresponding egress queue for that FC used by the IP network interface
the PW packet is forwarded on.
the queue-group name exists and the policer-id or policer-id plus queue-id exist, it is not
required to check that an instance of that queue-group exists in all egress network ports
which have network IP interfaces. The handling of this is dealt with in the data path as
follows:
a. When a PW packet for that FC is forwarded and an instance of the referenced
queue-group name exists on that egress port, the packet is processed by the
queue-group policer and is fed to the queue-group queue. If only a policer is
specified in the redirection command, then the packet is processed by the queue-
group policer and is then fed into the corresponding egress shared queue for that
FC defined in the network-queue policy applied to the egress of this port. If only
a queue is specified in the redirection command, the packet is fed to the queue-
group queue.
b. When a PW packet for that FC is forwarded and an instance of the referenced
queue-group name does not exist on that egress port, the PW packet is fed
directly to the corresponding egress shared queue for that FC defined in the
network-queue policy applied to the egress of this port.
c. If a network QoS policy is applied to the egress context of a PW, any PW FC,
which is not explicitly redirected in the network, QoS policy has the
corresponding packets feed directly the corresponding the egress shared queue
for that FC defined in the network-queue policy applied to the egress of this port.
