Chapter 29 Configuring FCoE
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:
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:
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 “Configuring IEEE 802.3x Link-Level Flow Control”
section on page 31-8.
Configuring LLDP
This section shows how to configure LLDP both globally and on individual interfaces. This section
includes the following topics:
• Configuring Global LLDP Commands, page 29-7
• Configuring Interface LLDP Commands, page 29-7
Command Purpose
Step 1
switch# configure terminal
Enters configuration mode.
Step 2
switch(config)# interface type slot/port
Specifies the interface to be changed.
Step 3
switch(config-if)# priority-flow-control
mode {auto | on }
Sets PFC mode for the selected interface.
Specify auto to negotiate PFC capability.
Specify on to force-enable PFC.
Command Purpose
switch(config-if)# no priority-flow-control
mode [auto | on ]
Disables the PFC capability for this interface.
