Dell(conf-qos-policy-out)# exit

Dell(conf)# qos-policy-output ipc ets

Dell(conf-qos-policy-out)# bandwidth-percentage 5

Dell(conf-qos-policy-out)# exit

Example of Configuring a DCB Output Policy to Apply ETS (Bandwidth Allocation and Scheduling) to

IPC, SAN, and LAN Priority Traffic

Dell(conf)# dcb-output ets

Dell(conf-dcb-out)# priority-group san qos-policy san

Dell(conf-dcb-out)# priority-group lan qos-policy lan

Dell(conf-dcb-out)# priority-group ipc qos-policy ipc

Example of Applying DCB Input and Output Policies to an Interface

Dell(conf)# interface tengigabitethernet 0/1

Dell(conf-if-te-0/1)# dcb-policy input pfc

Dell(conf-if-te-0/1)# dcb-policy output ets

Example of Configuring a QoS Output Policy to Specify Bandwidth Allocation to Different Traffic Types

if DCBx Version is CIN

Dell(conf)# qos-policy-output lan-q0

Dell(conf-qos-policy-out)# bandwidth-percentage 20

Dell(conf-qos-policy-out)# exit

Dell(conf)#q os-policy-output lan-q3

Dell(conf-qos-policy-out)# bandwidth-percentage 70

Dell(conf-qos-policy-out)# exit

Dell(conf)#policy-map-output ets-queues

Example of Creating a QoS Policy Map for DCBx CIN Bandwidth Allocation

Dell(conf)# policy-map-output ets-queues

Dell(conf-policy-map-out)# service-queue 0 qos-policy lan-q0

Dell(conf-policy-map-out)# service-queue 3 qos-policy lan-q3

Example of Applying the QoS Policy Map for DCBx CIN Bandwidth Allocation to an Interface

Dell(conf-if-te-0/1)# service-policy output ets-queues

Using PFC and ETS to Manage Converged Ethernet Traffic in a Switch Stack

The following example shows how to apply the DCB PFC input policy (ipc_san_lan) and ETS output

policy (

ets) on all ports in a switch stack.

This example references the PFC and ETS Configuration Examples section.

Example of Applying DCB PFC Input Policy and ETS Output Policy in a Switch Stack

Dell(conf)# dcb-policy output stack-unit all stack-ports all ets

Dell(conf)# dcb-policy input stack-unit all stack-ports all pfc

Hierarchical Scheduling in ETS Output Policies

ETS supports up to three levels of hierarchical scheduling.

For example, you can apply ETS output policies with the following configurations:

Priority group 1 Assigns traffic to one priority queue with 20% of the link bandwidth and strict-

priority scheduling.

Priority group 2 Assigns traffic to one priority queue with 30% of the link bandwidth.

Priority group 3 Assigns traffic to two priority queues with 50% of the link bandwidth and strict-

priority scheduling.
