Figure 1. S4148U-ON port groups
On a S4148U-ON, the activated FC interfaces depend on the currently congured port prole. For more information, see S4148U-ON port
proles.
To enable a bre channel interface:
1 Congure a unied port group in CONFIGURATION mode. Enter 1/1 for node/slot. The port-group range is 1–10.
port-group node/slot/port-group
2 Activate the unied port group for FC operation in PORT-GROUP mode.
mode FC {32g-2x | 32g-1x | 16g-2x |8g-4x}
• 8g-4x — Split a QSFP28 or SFP+ port group into four 8GFC interfaces.
• 16g-2x — Split a QSFP28 or SFP+ port group into two 16GFC interfaces.
• 16g-4x — Split a QSFP28 port group into four 16GFC interfaces.
• 32g-1x — Split a QSFP28 port group into one 32GFC interface.
• 32g-2x — Split a QSFP28 port group into two 32GFC 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) Recongure the interface speed for oversubscription in INTERFACE mode. Oversubscription allows a port to operate faster
for bursty storage trac.
speed {8 | 16 | 32 | auto}
6 Enable the FC interface in INTERFACE mode.
