– tlv: enables traces for DCBx TLVs.
Verifying the DCB Configuration
To display DCB configurations, use the following show commands.
Table 3. Displaying DCB Configurations
Command Output
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 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 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 {stack-unit unit-number |
tengigabitethernet slot/port} command.
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 stack-unit unit-number
command.
