Single-density QSFP28 interfaces

On the MX9116n Fabric Switching Engine module, a QSFP28 port group consists of one Ethernet 100G port. By default, QSFP28 port

groups 13 and 14 (physical ports 41 and 42) operate in 1x100GE mode.

For information about how to congure QSFP28-DD port groups 1 to 12 to operate in Ethernet mode, see Double-density QSFP28

interfaces.

For information about how to congure unied port groups 15 and 16 to operate in Ethernet or Fibre Channel mode, see Unied port

groups.

1 To congure a QSFP28 port-group interface, enter PORT-GROUP mode from CONFIGURATION mode. Enter 1/1 for node/slot. The

QSFP28 port-group range is 13 to 14.

port-group node/slot/port-group

2 Activate the QSFP28 port-group interface for Ethernet operation in PORT-GROUP mode.

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 QSFP28 port into two 50GE interfaces.

• 40g-1x — Split a QSFP28 port into one 40GE interface.

• 25g-4x — Split a QSFP28 port into four 25GE interfaces.

• 10g-4x — Split a QSFP28D port into four 10GE interfaces.

3 Return to CONFIGURATION mode.

4 Enter Ethernet Interface mode to congure 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 ports in a QSFP28 port group, enter the show port-group command. To display the Ethernet 25GE

subports, enter the show interfaces status command.
