Verifying the DCB Configuration
To display DCB configurations, use the following show commands.
Table 122. Displaying DCB Configurations
Command Output
show dot1p-queue mapping
Displays the current 802.1p priority-queue mapping.
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 qos priority-groups
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}
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
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}
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.
