Parameters
fcf: Specifies the FCF mode.
npv: Specifies the NPV mode.
transit: Specifies the Transit mode.
Usage guidelines
The switch supports the following FCoE modes:
•FCF mode—A switch operating in this mode is called an FCF switch. Its VFC interfaces support E
mode (E_Port) and F mode (F_Port).
•NPV mode—A switch operating in this mode is called an NPV switch. Its VFC interfaces support F
mode (F_Port) and NP mode (NP_Port).
•Transit mode—A switch operating in this mode is called a Transit switch. Its Ethernet interfaces can
operate in ENode mode or FCF mode.
An FC and FCoE-capable switch can operate in the following modes:
•FCF mode—When the switch is operating in this mode, it can perform one of the following
operations:
{Connect to the E_Port on another FCF switch through its E_Port.
{Connect to the N_Port on a node or the NP_Port on an NPV switch through its F_Port.
•NPV mode—When the switch is operating in this mode, it can perform one of the following
operations:
{Connect to the N_Port on a node through its F_Port.
{Connect to the F_Port on an FCF switch through its NP_Port.
•Transit mode—When the switch is operating in this mode, you can do perform one of the following
tasks:
{Restrict its Ethernet interface to receiving traffic only from an ENode by configuring the interface
to operate in ENode mode.
{Restrict its Ethernet interface to receiving traffic only from an FCF switch by configuring the
interface to operate in FCF mode.
•Non-FCoE mode—When the switch is operating in this mode, it is a standard switch and does not
provide any FC or FCoE capabilities.
The switch can only convert from non-FCoE mode to one FCoE mode, or vice versa. It cannot convert
directly among FCoE modes. To convert among FCoE modes, first convert the switch to non-FCoE mode.
After converting the switch to non-FCoE mode, FC and FCoE-related configurations in the original FCoE
mode are cleared.
Examples
# Configure the switch to operate in FCF mode.

Parameters
auto: Specifies the auto mode, so that the FC interface can operate in F mode or E mode through
dynamic negotiation.
e: Specifies the E mode.
f: Specifies the F mode.
np: Specifies the NP mode.
Usage guidelines
An FC switch supports E, F, and auto modes. An NPV switch supports F and NP modes.

Parameters
credit-value: Specifies the number of packets that the FC interface can continuously receive, in the range
of 1 to 15.
Usage guidelines
The BB_ Credit is a flow control mechanism used to ensure that an FC interface does not drop packets.
The BB_Credit value is configurable. Typically, you do not need to change the default value.

Default
The fill word mode is idle-arbff for an FC interface operating at 8 Gbps.
Views

Predefined user roles
network-admin
Parameters
idle-arbff: Specifies the idle-arbff mode. This mode uses the idle primitive signal in the link initialization
phase and uses the ARBff primitive signal as the fill word.
idle-idle: Specifies the idle-idle mode. This mode uses the idle primitive signal in the link initialization
phase and uses the idle primitive signal as the fill word.
Usage guidelines
This command is available on only FC interfaces operating at 8 Gbps. This command does not take
effect on FC interface operating at 2 Gbps or 4 Gbps, and these FC interfaces supports only the fill word
mode idle-idle.
When FC interfaces operating at 8 Gbps fail to communicate, you can use this command to adjust the
fill word of these FC interfaces.
To make the fill word mode configuration take effect, you must re-enable the FC interface by using the
shutdown command and then the undo shutdown command.
Examples
# Configure the fill word mode as idle-idle for FC 1/0/1 operating at 8 Gbps.
