Usage
Information
To clear the PFC TLV counters, use the clear pfc counters interface command.
The following describes the show interface pfc summary command shown in the following
example.
Field Description
Interface Interface type with stack-unit and port number.
Admin mode is on
Admin is enabled
PFC admin mode is on or off with a list of the configured PFC priorities. When the
PFC admin mode is on, PFC advertisements are enabled to be sent and received
from peers; received PFC configuration take effect. The admin operational status
for a DCBX exchange of PFC configuration is enabled or disabled.
Remote is
enabled, Priority
list Remote
Willing Status is
enabled
Operational status (enabled or disabled) of peer device for DCBX exchange of PFC
configuration with a list of the configured PFC priorities. Willing status of peer
device for DCBX exchange (Willing bit received in PFC TLV): enabled or disable.
Local is enabled DCBX operational status (enabled or disabled) with a list of the configured PFC
priorities.
Operational
status (local
port)
Port state for current operational PFC configuration:
● Init: Local PFC configuration parameters were exchanged with the peer.
● Recommend: Remote PFC configuration parameters were received from the
peer.
● Internally propagated: PFC configuration parameters were received
from the configuration source.
PFC DCBX Oper
status
Operational status for the exchange of the PFC configuration on the local port:
match (up) or mismatch (down).
State Machine
Type
Type of state machine used for DCBX exchanges of the PFC parameters: Feature
— for legacy DCBX versions; Symmetric — for an IEEE version.
TLV Tx Status Status of the PFC TLV advertisements: enabled or disabled.
PFC Link Delay Link delay (in quanta) used to pause specified priority traffic.
