Verifying the DCB Configuration

To display DCB configurations, use the following show commands.
Table 20. Displaying DCB Configurations
Command
show qos dot1p-queue mapping
show dcb [stack-unit unit-number]
show qos priority-groups
show interface port-type pfc {summary | detail} Displays the PFC configuration applied to ingress traffic on an
show interface port-type pfc statistics
show interface port-type ets {summary | detail} Displays the ETS configuration applied to egress traffic on an
show interface port-type DCBx detail
show stack-unit {0-11 | all} stack ports all
pfc details
show stack-unit {0-11 | all} stack ports all
ets details
Examples of the show Commands
The following example shows the show dot1p-queue mapping command.
Dell(conf)# show qos dot1p-queue-mapping
Dot1p Priority: 0 1 2 3 4 5 6 7
Queue : 0 0 0 1 2 3 3 3
Output
Displays the current 802.1p priority-queue mapping.
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.
Displays the ETS priority groups configured on the switch, including
the 802.1p priority classes and ID of each group.

To clear PFC TLV counters, use the clear pfc counters
interface port-type slot/port command.
Displays counters for the PFC frames received and transmitted (by
dot1p priority class) on an interface.
You can use the show interface pfc statistics
command even without enabling DCB on the system.

Displays the PFC configuration applied to ingress traffic, including
priorities and link delay.
Displays the ETS configuration applied to ingress traffic on stack-
links, including priorities and link delay.
