The following example shows how to force-enable PFC on an interface:
switch# configure terminal
switch(config)# interface ethernet 1/2
switch(config-if)# priority-flow-control mode on
To disable PFC capability for an interface, perform this task:
Command
switch(config-if)# no
priority-flow-control mode

Configuring IEEE 802.3x Link-Level Flow Control

By default, link-level flow control capability on Ethernet interfaces is disabled. You can enable link-level
flow-control capability for the transmit and receive directions.
To enable link-level flow control capability, perform this task:
Command
Step 1
switch# configure terminal
Step 2
switch(config)# interface type slot/port
Step 3
switch(config-if)# flowcontrol [receive
{on|off}] [transmit {on|off}]
The following example enables link-level flow control frames on an interface:
switch# configure terminal
switch(config)# interface ethernet 1/2
switch(config-if)# flowcontrol receive on transmit on
To disable link-level flow control, perform this task:
Command
switch(config-if)# no flowcontrol
[receive {on|off}] [transmit {on|off}]
