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.
• The switch consists of six 40G ports (49,50,51,52,53,54) that can be split into 10G ports.
• In stacking, configure profile first before provisioning for new units. Otherwise it is mandatory to reload for profile to take effect.
• If there is a mismatch in fan-out profile between master and the new member in stacking, the master re-configures the member with
its quad-mode profile, quad-mode, and stack-group configuration and then reset the member. To avoid stack split during profile
mismatch, the master does stack group configurations of the new member.
To configure the quad-port-profile, use the following command:
CONFIGURATION mode
stack-unit stack-unit number port port-number portmode quad
The defaults ports are:
49,50,51,52,53,54
To display the Fan-out capability profile, use the following show command:
show system stack-unit stack-unit number fanout configured
Example of the
show Command
The following example shows the show system stack-unit stack-unit number fanout
configured command.
Dell#show system stack-unit 1 fanout configured

The following example shows the interface status before splitting a 40G interface:
Dell#show interfaces status

The following example shows splitting a 40G interface:
Dell(conf)#stack-unit 1 port 49 portmode quad
Warning: Enabling Quad mode on stack-unit 1 port 49. Please verify whether the configs related
to interface Fo 1/49 are cleaned up before proceeding further.
