Chapter 29 Configuring FCoE
Configuring FCoE
Enabling FCoE
You need to enable the FCoE capability after the FC_FEATURES_PKG is installed. To enable FCoE,
perform this task:
The following example shows how to enable FCoE on the switch:
switch# configure terminal
switch(config)# feature fcoe
witch(config)# 2008 Nov 11 20:43:38 switch %$ VDC-1 %$ %PFMA-2-FC_LICENSE_DESIRED: FCoE/FC
feature will be enabled after the configuration is saved followed by a reboot
Note After you enable the FCoE capability, you must reboot the Cisco Nexus 5000 Series switch before you
can use the features.
Enabling FCoE on Ethernet Interfaces
By default, 10-Gigabit Ethernet interfaces negotiate FCoE capability with the adapter. You can override
the negotiation result by force-enabling the FCoE capability. To force-enable the FCoE capability,
perform this task:
The following example shows how to force-enable FCoE for an Ethernet interface:
switch# configure terminal
switch(config)# interface ethernet 1/4
switch(config-if)# fcoe mode on
To disable the FCoE capability, perform this task:
Command Purpose
Step 1
switch# configure terminal
Enters configuration mode.
Step 2
switch(config)# feature fcoe
Enables the FCoE capability.
Command Purpose
Step 1
switch# configure terminal
Enters configuration mode.
Step 2
switch(config)# interface type slot/port
Enters interface configuration mode for the specified
interface.
Step 3
switch(config-if)# fcoe mode {auto | on}
When you set the FCoE parameter to auto, the
interface negotiates the setting with the connected
adapter. FCoE will not be enabled on the interface if
the adapter does not support FCoE.
If the mode is set it to on, the negotiation result is
ignored and FCoE is set to enabled on the interface.
Command Purpose
switch(config-if)# no fcoe mode [auto |
on]
Disables FCoE capability for this interface.
