The 40G ports on X670-G2 and X770 switches can be partitioned into 4x10G and 1x40G modes.
To partition the ports, enter the following command:
configure ports [port_list | all] partition [4x10G | 1x40G | 1x100G | 10x10G ]
After you make a configuration change, you must do one of the following to apply the change:
Note
Because of the nature of these ports at the physical layer level, the 10G side may show a remote or local linkup. A configuration change is not applied until the affected slot is disabled and enabled or the switch is rebooted.
