• Uses the DSCP values as configured on the ScaleIO-data01 port group
• Maps DSCP value to a specified queue
• Prioritizes egress traffic on uplinks through strict queuing
Note: The example below uses a DCSP value of 46 and a queue value of 3. The choice of values is
arbitrary and is used to show any DSCP value can be manually mapped to any queue.
Leaf switch configuration procedure:
1. Access the command line and enter configuration mode.
2. Create a class map to match traffic for the DSCP value.
class-map type qos ClassQoS_Storage
match ip dscp 46
3. Create a policy map to map the class of traffic to a specific queue.
policy-map type qos PolicyQoS_Storage
class ClassQoS_Storage
set qos-group 3
4. Apply the policy map to the ingress interfaces using an input service policy.
interface ethernet 1/1/1
service-policy input type qos PolicyQos_Storage
a. Repeat step 4 for all ingress interfaces that have ScaleIO-data01 traffic.
5. Create a class map to match traffic for the queue.
class-map type queuing ClassQueue_Storage
match queue 3
6. Create a policy map to map the class of traffic to a strict priority.
policy-map type queuing PolicyQueue_Strict
class ClassQueue_Storage
priority
7. Apply the policy map to an uplink interface using an output service policy.
interface ethernet 1/1/42
service-policy output type queuing PolicyQueue_Strict
a. Repeat step 7 for all leaf uplink interfaces.
The configuration in the above steps can be applied to any input and uplink interface throughout the leaf-
spine topology. This example only implements priority queuing at the uplink interfaces. Tagging or marking
occurs at the distributed port groups, and mapping occurs at the switch interfaces to the nodes.
