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.
• QSFP28 port groups 13 and 14 operate in Ethernet 1x100GE mode by default.
• Unied port groups 15 and 16 operate in Ethernet 1x100GE mode by default, and support Fibre Channel and other Ethernet modes. In
Ethernet mode, unied port groups 15 and 16 contain dierent breakout options than QSFP28-DD and QSFP28 port groups 1 to 14.
Figure 6. MX9116n Fabric Switching Engine unied port groups
To enable Ethernet interfaces in a unied port group:
1 Congure a unied 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 unied port group for Ethernet operation in PORT-GROUP mode. To activate a unied 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.
