Using Pfc And Ets To Manage Converged Ethernet Traffic In A Switch Stack - Dell Force10 S4810P Configuration Manual

Figure 13-20. Example: DCB PFC and ETS Configuration (Continued)
Configure a DCB output policy for applying 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
Apply DCB input and output policies to a port 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
If the DCBx version is CIN, configure a QoS output policy to specify bandwidth allocation to different
traffic types:
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
Create 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
Apply the QoS policy map for DCBx CIN bandwidth allocation to an interface:
FTOS(conf-if-te-0/1)# service-policy output ets-queues

Figure 13-21. Apply DCB PFC Input Policy and ETS Output Policy in a Switch Stack Example
On the stack master, apply DCB PFC input and ETS output policies to all port interfaces on stacked
switches:
FTOS(conf)# dcb-policy output stack-unit all stack-ports all ets
FTOS(conf)# dcb-policy input stack-unit all stack-ports all pfc
