Port Level / Scheduler Policy / Network Queue Policy

Below we can see the egress scheduler policy and network egress queue policy applied to a port:

# show port 1/x1/1/c17/1 detail | match Pol
Net. Egr. Queue Pol: network-queue-m
Egr. Sched. Pol    : 100GE
Accounting Policy  : None                       Collect-stats    : Disabled

 

Ports have 8 queues by default, we can see that the scheduler policy doesn't apply settings to all 8 queues:

Looking at the egress network policy we can see that only queues 1, 4, 5, and 6 are configured, note that queue 9 is orphanded:

Check the network QoS policy applied to the pseudowires/spoke-SDPs on ingress and egress. It can be seen that network QoS policy 300 is applied to the stitched pseudowire example below:

# show service id 123 sdp 38:980000630 detail | match expression "Qos|QGrp"
Ingress Qos Policy : 300 Egress Qos Policy : (none)
Ingress FP QGrp : test Egress Port QGrp : (none)
Ing FP QGrp Inst : 23 Egr Port QGrp Inst: (none)

# show service id 123 sdp 14720:980000630 detail | match expression "Qos|QGrp"
Ingress Qos Policy : (none) Egress Qos Policy : 300
Ingress FP QGrp : (none) Egress Port QGrp : test
Ing FP QGrp Inst : (none) Egr Port QGrp Inst: 23

 

We can see that network QoS policy 300 maps traffic into egress queue 1:

# show qos port-scheduler-policy "100GE" sap-egress 300
