FTOS(conf-qos-policy-out)# bandwidth-percentage 5
FTOS(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
FTOS(conf)# dcb-output ets
FTOS(conf-dcb-out)# priority-group san qos-policy san
FTOS(conf-dcb-out)# priority-group lan qos-policy lan
FTOS(conf-dcb-out)# priority-group ipc qos-policy ipc
Example of Applying DCB Input and Output Policies to an Interface
FTOS(conf)# interface tengigabitethernet 0/1
FTOS(conf-if-te-0/1)# dcb-policy input pfc
FTOS(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
FTOS(conf)# qos-policy-output lan-q0
FTOS(conf-qos-policy-out)# bandwidth-percentage 20
FTOS(conf-qos-policy-out)# exit
FTOS(conf)#q os-policy-output lan-q3
FTOS(conf-qos-policy-out)# bandwidth-percentage 70
FTOS(conf-qos-policy-out)# exit
FTOS(conf)#policy-map-output ets-queues
Example of Creating a QoS Policy Map for DCBx CIN Bandwidth Allocation
FTOS(conf)# policy-map-output ets-queues
FTOS(conf-policy-map-out)# service-queue 0 qos-policy lan-q0
FTOS(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
FTOS(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
FTOS(conf)# dcb-policy output stack-unit all stack-ports all ets
FTOS(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.
