tlv: enables traces for DCBx TLVs.
Verifying the DCB Configuration
To display DCB configurations, use the following show commands.
Table 20. Displaying DCB Configurations
Command Output
show dot1p-queue mapping
Displays the current 802.1p priority-queue mapping.
show dcb linecard unit-number
Displays the data center bridging status, number of PFC-
enabled ports, and number of PFC-enabled queues. You can
optionally specify the linecard. The range for line card is from
0 to 11.
show qos dcb-map name
Displays the DCB map configured on the switch.
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.
You can use the show interface pfc statistics
command even without enabling DCB on the system.
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.
show interface port-type slot/port DCBx
detail
Plays the DCBx configuration on an interface.
show linecard linecard-number port-set port
set-number backplane all pfc details
Displays the PFC configuration applied to ingress traffic,
including priorities and link delay.
show linecard linecard-number port-set port
set-number backplane all ets details
Displays the ETS configuration applied to ingress traffic on
stack-links, including priorities and link delay.
The following example shows the show dot1p-queue mapping command.
Dell(conf)# show dot1p-queue-mapping
Dot1p Priority: 0 1 2 3 4 5 6 7
Queue : 0 0 0 1 2 3 3 3
The following example shows the show dcb command.
Dell#show dcb linecard 2 port-set 0
DCB Status: Enabled, PFC Queue Count: 2
