Splitting 40G Ports without Reload
You can split 40G interfaces into 10G ports without reboot. You can also combine the split ports to create a 40G port without reload.
On a device, fan-out prole constructs automatically with default 24 ports
(2,4,6,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,27,29,31) . These ports can be changed to 40G to 10G mode or vice-versa without
reload.
When a non-supported prole release is upgraded to a supported prole release, the fan-out congured ports get automatically
included in the prole. In fan-out mode, if a system is upgraded with 25 or 26 ports, only 24 ports get upgraded to fan-out mode. The
rest of the ports put to default 40G mode.
In stacking, congure prole rst before provisioning for new units. Otherwise it is mandatory to reload for prole to take eect.
If there is a mismatch in fan-out prole between master and the new member in stacking, the master re-congures the member with
its quad-mode prole, quad-mode, and stack-group conguration and then reset the member. To avoid stack split during prole
mismatch, the master does stack group congurations of the new member.
To congure the quad-port-prole, use the following command:
CONFIGURATION mode
stack-unit [stack-unit number] quad-port-profile [default | list of ports]
The defaults ports are:
2,4,6,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,27,29,31
Example:
stack-unit stack-unit-number quad-port-profile [default | list of ports]
To display the Fan-out capability prole, use the following show command:
show system stack-unit quad-port-profile
Example of the
show Command
The following example shows the system stack-unit quad-port-profile command.
Dell(conf)#stack-unit 1 port 24 portmode quad
Warning: Enabling quad mode on stack-unit 1 port 24. Please verify whether the
configs related to interface Fo 1/24 are cleaned up before proceeding further.

NOTE: Save and reload, after the setting takes

You can only split the 40G ports in the top row (odd numbered ports) on a 16X40G module. If you congure 4X10G on a 40G interface, the
subsequent even numbered interface is removed and unavailable for use.
The following example shows the interface status before splitting a 40G interface:
