Figure 13-19. PFC and ETS Configuration Command Example
Configure QoS priority-queue assignment to honor dot1p priorities or use L2 class maps to mark and
map ingress traffic to output queues; for example:
FTOS(conf)# service-class dynamic dot1p
Or
FTOS(conf)# interface tengigabitethernet 0/1
FTOS(conf-if-te-0/1)# service-class dynamic dot1p
Configure a DCB input policy for applying PFC to lossless SAN priority traffic:
FTOS(conf)# dcb-input ipc_san_lan
FTOS(conf-qos-policy-in)# pfc mode on
FTOS(conf-qos-policy-in)# pfc priority 3
Configure an ETS priority group:
FTOS(conf)# priority-group san
FTOS(conf-pg)# priority-list 3
FTOS(conf-pg)# set-pgid 1
FTOS(conf-pg)# exit
FTOS(conf)# priority-group ipc
FTOS(conf-pg)# priority-list 4
FTOS(conf-pg)# set-pgid 2
FTOS(conf-pg)# exit
FTOS(conf)# priority-group lan
FTOS(conf-pg)# priority-list 0-2,5-7
FTOS(conf-pg)# set-pgid 3
FTOS(conf-pg)# exit
Configure an ETS output policy for egress traffic:
FTOS(conf)# qos-policy-output san ets
FTOS(conf-qos-policy-out)# bandwidth-percentage 50
FTOS(conf-qos-policy-out)# exit
FTOS(conf)# qos-policy-output lan ets
FTOS(conf-qos-policy-out)# bandwidth-percentage 45
FTOS(conf-qos-policy-out)# exit
FTOS(conf)# qos-policy-output ipc ets
FTOS(conf-qos-policy-out)# bandwidth-percentage 5
FTOS(conf-qos-policy-out)# exit
