Deployment Guide

• Enable DCBx debugging.
EXEC PRIVILEGE mode
debug DCBx {all | auto-detect-timer | config-exchng | fail | mgmt | resource | sem | tlv}
• all: enables all DCBx debugging operations.
• auto-detect-timer: enables traces for DCBx auto-detect timers.
• config-exchng: enables traces for DCBx conguration exchanges.
• fail: enables traces for DCBx failures.
• mgmt: enables traces for DCBx management frames.
• resource: enables traces for DCBx system resource frames.
• sem: enables traces for the DCBx state machine.
• tlv: enables traces for DCBx TLVs.
Verifying the DCB Conguration
To display DCB congurations, use the following show commands.
Table 97. 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.
