For information about how to configure single-density QSFP28 Ethernet port groups 13 and 14, see Single-density QSFP28 interfaces.
For information about how to configure unified port groups 15 and 16 to operate in Ethernet or Fibre Channel mode, see Unified port
groups.
If an MX9116n module is in SmartFabric mode, use the OpenManage Enterprise - Modular interface to configure breakout interfaces
and speed on a QSFP28-DD port.
1. To configure a QSFP28-DD port interface, enter PORT-GROUP mode from CONFIGURATION mode. Enter 1/1 for node/slot. The
QSFP28-DD port-group range is 1 to 12.
port-group node/slot/port-group
2.
(Optional) To verify the current QSFP28-DD port-group configuration, enter the show port-group command.

To reset a QSFP28-DD port group to its default setting, enter the no mode command in PORT-GROUP mode. This command sets
QSFP-DD port groups 1 to 9 to 8x25GE FEM mode and QSFP-DD port groups 10 to 12 to 2x100GE mode.

3. To activate a QSFP28-DD interface for Ethernet operation, enter the mode Eth command in PORT-GROUP mode.
mode Eth {100g-2x | 50g-4x | 40g-2x | 25g-8x fabric-expander-mode | 25g-8x | 10g-8x}
100g-2x — Split a QSFP28-DD port into two 100GE interfaces.
50g-4x — Split a QSFP28-DD port into four 50GE interfaces.
40g-2x — Split a QSFP28-DD port into two 40GE interfaces.
25g-8x fabric-expander-mode — Split a QSFP28-DD port into eight 25GE interfaces for connection only to an MX7116n
Fabric Expander.
25g-8x — Split a QSFP28-DD port into eight 25GE interfaces.
10g-8x — Split a QSFP28-DD port into eight 10GE interfaces.
4. Return to CONFIGURATION mode.
exit
5. Enter Ethernet Interface mode to configure other settings. Enter a single interface, a hyphen-separated range, or multiple interfaces
separated by commas.
interface ethernet node/slot/port[:subport]
To display the Ethernet 100GE port configuration in a QSFP28-DD port group, enter the show port-group command. To display
the Ethernet 25GE subport configuration, enter the
show interfaces status command.
