7. To check the currently available active and port options, use the NIC# and run
the following command:
epct64e.efi -nic=1 -get
Under the Active Option listing, the "X" will indicate the option currently selected.
In the example below, the current active option is 2x1x100 (2 ports, each at
100G).
Note: Be sure to connect the proper cables to the matching port configura-
tion (ex. connect 2x1x100 = QSFP28).
8. In the example below, the current port option is 4x25G (1 port at 4x25G). This
means that Port 2 will be 4x25G and Port 1 will be disabled. Based on that,
to split to other port options, please use the following command:
epct64e.efi -nic=1 -set=4x25
Then reboot the system to apply changes.
Note: Be sure to connect the proper cables to the matching port configura-
tion (ex. connect 4x25 = Breakout cable QSFP28 to 4xSFP28).
