Verifying the DCB Configuration To display DCB configurations, use the following show commands. Table 3. Displaying DCB Configurations Command Output show dcb [stack-unit unit-number] Displays the data center bridging status, number of PFC-enabled ports, and number of PFC-enabled queues. On the master switch in a stack, you can specify a stack-unit number. The range is from 0 to 5. show interface port-type slot/port pfc Displays counters for the PFC frames received and statistics transmitted (by dot1p priority class) on an interface. show interface port-type slot/port pfc {summary | detail} Displays the PFC configuration applied to ingress traffic on an interface, including priorities and link delay. To clear PFC TLV counters, use the clear pfc counters {stack-unit unit-number | tengigabitethernet slot/port} command. show interface port-type slot/port ets {summary | detail} Displays the ETS configuration applied to egress traffic on an interface, including priority groups with priorities and bandwidth allocation. To clear ETS TLV counters, enter the clear ets counters stack-unit unit-number command.
