Table 8-2. Displaying DCB Configurations
Command Output
show dot1p-queue mapping (Figure 8-5) Displays the current 802.1p priority-queue mapping.
show dcb [stack-unit unit-number] (Figure 8-6) Displays 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. Valid values: 0 to 5.
show qos dcb-input [pfc-profile] (Figure 8-7) Displays the PFC configuration in a DCB input policy.
show qos dcb-output [ets-profile] (Figure 8-8) Displays the ETS configuration in a DCB output policy.
show qos priority-groups (Figure 8-9) Displays the ETS priority groups configured on the switch, including the
802.1p priority classes and ID of each group.
show interface port-type slot/port pfc {summary
| detail} (Figure 8-10)
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 interface port-type
slot/port command.
show interface port-type slot/port pfc statistics
(Figure 8-11)
Displays counters for the PFC frames received and transmitted (by dot1p
priority class) on an interface.
show interface port-type slot/port ets {summary
| detail} (Figure 8-12 and Figure 8-13)
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 interface port-type
slot/port command.
