Dell EMC SmartFabric OS10 User Guide Release 10.5.0

• mode Eth — Configure a port group in Ethernet mode and set the speed to:
  • 100g-2x — Split a QSFP28-DD port into two 100GE interfaces.
  • 100g-1x — Reset a QSFP28 port group to 100GE mode.
  • 50g-2x — Split a QSFP28 port into two 50GE interfaces.
  • 40g-2x — Split a port group into two 40GE interfaces.
  • 40g-1x — Set a port group to 40G mode for use with a QSFP+ 40GE transceiver.
  • 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 — Configure 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.

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.
• Unified port groups 15 and 16 operate in ethernet 1x100GE mode.

• The mode {FC | Eth} command configures a port group to operate at line rate and guarantees no traffic loss.
• To configure oversubscription on a FC interface, use the speed 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.
