MX9116n Fabric Switching Engine
On the MX9116n Fabric Switching Engine module:
● QSFP28-DD port groups 1 to 12 operate only in Ethernet mode. For more information, see Double-density QSFP28 interfaces
on page 313.
● QSFP28 port groups 13 and 14 operate in Ethernet 1x100GE mode by default.
● Unified port groups 15 and 16 operate in Ethernet 1x100GE mode by default, and support Fibre Channel and other Ethernet
modes. In Ethernet mode, unified port groups 15 and 16 contain different breakout options than QSFP28-DD and QSFP28
port groups 1 to 14.
● If an MX9116n module is in SmartFabric mode, use the OpenManage Enterprise - Modular interface to configure breakout
interfaces and speed for a unified port group.
Figure 2. MX9116n Fabric Switching Engine unified port groups
To enable Ethernet interfaces in a unified port group:
1. Configure a unified port group in CONFIGURATION mode. Enter 1/1 for node/slot. The port-group range depends on the
switch.
port-group node/slot/port-group
2. Activate the unified port group for Ethernet operation in PORT-GROUP mode. To activate a unified port group in Fibre
Channel mode, see Fibre Channel interfaces. The available options depend on the switch.
mode Eth {100g-1x | 50g-2x | 40g-1x | 25g-4x | 10g-4x}
● 100g-1x — Reset a port group to 100GE mode.
● 50g-2x — Split a port group into two 50GE interfaces.
● 40g-1x — Set a port group to 40GE mode for use with a QSFP+ 40GE transceiver.
● 25g-4x — Split a port group into four 25GE interfaces.
● 10g-4x — Split a port group into four 10GE interfaces.
3. Return to CONFIGURATION mode.

4. Enter Ethernet Interface mode to configure other settings. Enter a single interface, a hyphen-separated range, or multiple
interfaces separated by commas.
