Configuring LLDP

This example shows how to disable FCoE for an Ethernet interface:
switch# configure terminal
switch(config)# interface ethernet 1/4
switch(config-if)# no fcoe mode auto
The fcoe command can only be applied to a physical Ethernet interface.
Configuring Priority Flow Control
By default, the Ethernet interfaces negotiate PFC capability with the adapter. You can override the
negotiation result by force-enabling the PFC capability. To force-enable the PFC capability, perform this
task:
Command
Step 1
switch# configure terminal
Step 2
switch(config)# interface type slot/port
Step 3
switch(config-if)# priority-flow-control
mode {auto | on }
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 this interface, perform this task:
Command
switch(config-if)# no priority-flow-control
mode [auto | on ]
Configuring IEEE 802.3x Link-Level Flow Control
By default, link-level flow control capability on Ethernet interfaces is disabled. Only enable the
link-level flow control capability if PFC is disabled on the interface.
To configure link-level flow control, see the
section on page
