– 25g-8x fabric-expander-mode — Split a QSFP28-DD port into eight 25GE interfaces for
connection to a Fabric Expander.
– 25g-8x — Split a port group into eight 25GE interfaces.
– 25g-4x — Split a port group into four 25GE interfaces.
– 10g-8x — Split a port group into eight 10GE interfaces.
– 10g-4x — Split a port group into four 10GE interfaces.
• mode FC — Congure a port group in Fibre Channel mode and set the speed to:
– 32g-4x — Split a port group into four 32GFC interfaces.
– 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.
MX9116n Fabric Switching Engine:
• QSFP28-DD port groups 1 to 9 operate in 8x25GE fabric-expander mode (FEM).
• QSFP28-DD port groups 10 to 12 operate in 2x100GE mode.
• QSFP28 port groups 13 and 14 operate in 1x100GE mode.
• Unied port groups 15 and 16 operate in ethernet 1x100GE mode.
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.
• 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.
• 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.
Example
OS10(conf-pg-1/1/2)# mode FC 16g-4x
OS10(conf-pg-1/1/8)# mode Eth 10g-4x
