Verifying the DCB Conguration
To display DCB congurations, use the following show commands.
Table 10. Displaying DCB Congurations
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 congured 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 conguration applied to ingress trac 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 conguration applied to egress trac 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.
