Fibre Channel interfaces
OS10 unified port groups support Fibre Channel (FC) interfaces. A unified port group operates in Fibre Channel or Ethernet
mode. To activate FC interfaces, configure a port group to operate in Fibre Channel mode and specify the port speed. By
default, FC interfaces are disabled. To enable an FC interface for data transmission, enter the no shutdown command.
On a S4148U-ON, FC interfaces are available in all port groups. The activated FC interfaces depend on the currently configured
port profile. For more information, see S4148U-ON port profiles.

To enable a Fibre Channel interface:
1. Configure a unified port group in CONFIGURATION mode. Enter 1/1 for node/slot. The port-group range depends on the
switch.
port-group node/slot/port-group
2. Activate the unified port group for FC operation in PORT-GROUP mode. The available FC modes depend on the switch.
mode fc {32g-2x | 32g-1x | 16g-4x | 16g-2x |8g-4x}
● 8g-4x — Split a unified port group into four 8 GFC interfaces.
● 16g-2x — Split a unified port group into two 16 GFC interfaces.
● 16g-4x — Split a unified port group into four 16 GFC interfaces; supports 4x32GFC oversubscription.
● 32g-1x — Split a unified port group into one 32 GFC interface.
● 32g-2x — Split a unified port group into two 32 GFC interfaces.
3. Return to CONFIGURATION mode.
exit
4. Enter FC Interface mode to enable data transmission. Enter a single interface, a hyphen-separated range, or multiple
interfaces separated by commas.
interface fibrechannel node/slot/port[:subport]
5. (Optional) Reconfigure the interface speed for oversubscription in INTERFACE mode. Oversubscription allows a port to
operate faster for bursty storage traffic.
speed {8 | 16 | 32 | auto}
6. Enable the FC interface in INTERFACE mode.
