Usage Information
You can split a 40G port into four 10G ports.
You can use the stack-unit portmode command to dynamically fan-out 40G ports into 10G ports and vice-
versa without reloading a switch.
The port must be in a default conguration before it can be split. As the 40G port is lost in the conguration when
the port is split, ensure that you remove the port from other L2/L3 feature congurations.
You cannot use this command if you use an LR4 optics.
The following guidelines apply to the splitting of 40GbE QSFP+ ports into four 10GbE SFP+ ports by using the
stack-unit portmode command on the S6000 or S6000–ON platform.
• On an S6000 switch, the fan-out prole constructs automatically with default 24 ports on quad-port-prole.
The default ports are, 0,8,16,24,32,36,40,44,48,52,56,60,64,68,72,76,80,84,88,92,100,108,116,124.

Dell(conf)#
switchport
Place an interface in Layer 2 mode.
Syntax
switchport [[backup interface {interface | port-channel number}] | mode
private-vlan {host | promisucous | trunk}]
To remove an interface from Layer 2 mode and place it in Layer 3 mode, enter the no switchport command. If
a switchport backup interface is congured, rst remove the backup conguration. To remove a switchport backup
interface, enter the no switchport backup interface command.
