Verifying DCB Configuration
Use the show commands in Table 6-2 to display DCB configurations and statistics.
Figure 6-8. show dcb Command Example
Figure 6-9. show interface pfc statistics Command Example
Table 6-2. Displaying DCB Configurations
Command Output
show dcb [stack-unit unit-number] (Figure 6-8) Displays 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. Valid values: 0 to 5.
show interface port-type slot/port pfc statistics
(Figure 6-9)
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} (Figure 6-10)
Displays the PFC configuration applied to ingress traffic on an interface,
including priorities and link delay.
To clear PFC TLV counters on all ports or a specified port, use the clear pfc
counters {stack-unit
unit-number | tengigabitethernet slot/port} command.
show interface port-type slot/port ets {summary
| detail} (Figure 6-11 and Figure 6-12)
Displays the ETS configuration applied to egress traffic on an interface,
including priority groups with priorities and bandwidth allocation.
To clear ETS TLV counters on all ports or a specified port, enter the clear
ets counters stack-unit
unit-number command.
