1. To configure 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 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 ports in a QSFP28 port group, enter the show port-group command. To display the Ethernet
25GE subports, enter the show interfaces status command.
