• mode FC — Congure a port group in Fibre Channel mode and set the speed to:
– 32g-2x — Split a port group into two 32GFC interfaces, subports 1 and 3.
– 32g-1x — Split a port group into one 32GFC interface, subport 1.
– 16g-4x — Split a port group into four 16GFC interfaces; supports 4x32GFC oversubscription.
– 16g-2x — Split a port group into two 16GFC interfaces using ports 1 and 3.
– 8g-4x — Split a port group into four 8GFC interfaces.
Default S4148U-ON: Depends on the port prole activated.
Command Mode PORT-GROUP
Usage Information
• The mode {FC | Eth} command congures a port group to operate at line rate and guarantees no trac
loss.
• The no version of the command resets port-group interfaces to the default Ethernet port mode/speed. Use
the
no mode command before you reset the mode on an interface.
• To congure oversubscription on a FC interface, use the speed command.
• To congure breakout interfaces on an Ethernet port, use the interface breakout command.
• To view the currently active ports and subports, use the show interfaces status command.
Example
OS10(conf-pg-1/1/2)# mode FC 16g-2x
OS10(conf-pg-1/1/8)# mode Eth 10g-4x
Example: Reset
mode
OS10(conf-pg-1/1/2)# mode FC 16g-2x
OS10(conf-pg-1/1/2)# no mode
OS10(conf-pg-1/1/2)# mode Eth 10g-4x

mtu
Sets the link maximum transmission unit (MTU) frame size for an Ethernet L2 or L3 interface.
Syntax
