Verifying the DCB Conguration
To display DCB congurations, use the following show commands.
Table 18. Displaying DCB Congurations
Command Output
show qos dot1p-queue mapping
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.
show interface port-type 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 pfc statistics
Displays counters for the PFC frames received and transmitted (by
dot1p priority class) on an interface.
show interface port-type 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.
show interface port-type DCBx detail
Plays the DCBx conguration on an interface.
show
Displays the PFC conguration applied to ingress trac, including
priorities and link delay.
Displays the ETS conguration applied to ingress trac, including
priorities and link delay.
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 : 1 0 2 3 4 5 6 7
The following example shows the output of the show qos dcb-map test command.
