Displaying DCB ConfigurationsCommand Outputshow dcb [stack-unit unit-number] (Figure 6-8) Displays data center bridging status, number of PFC-enabled ports, andnumber of PFC-enabled queues. On the master switch in a stack, you canspecify a stack-unit number. Valid values: 0 to 5.show interface port-type slot/port pfc statistics(Figure 6-9)Displays counters for the PFC frames received and transmitted (by dot1ppriority class) on an interface.show interface port-type slot/port pfc {summary| detail} (Figure 6-10)Displays the PFC configuration applied to ingress traffic on an interface,including priorities and link delay.To clear PFC TLV counters on all ports or a specified port, use the clear pfccounters {stack-unit unit-number | tengigabitethernet slot/port} command.show interface port-type slot/port ets {summary| detail} (Figure 6-11 and Figure 6-12)Displays the ETS configuration applied to egress traffic on an interface,including priority groups with priorities and bandwidth allocation.To clear ETS TLV counters on all ports or a specified port, enter the clearets counters stack-unit unit-number command.FTOS# show dcbstack-unit 0 port-set 0DCB Status : EnabledPFC Port Count : 56 (current), 56 (configured)PFC Queue Count : 2 (current), 2 (configured)FTOS#show interfaces tengigabitethernet 0/3 pfc statisticsInterface TenGigabitEthernet 0/3Priority Rx XOFF Frames Rx Total Frames Tx Total Frames-------------------------------------------------------------------------------0 0 0 01 0 0 02 0 0 03 0 0 04 0 0 05 0 0 06 0 0 07 0 0 0
