Version Description
8.3.11.1 Introduced on the Z9000.
8.3.7.1 Introduced on the S4810.
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 configuration before it can be split. As the 40G port is lost in the
configuration when the port is split, ensure that you remove the port from other L2/L3 feature
configurations.
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.
● For S6000–ON, the default ports on quad-
port-profile 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.
For example, stack-unit 1 quad-port-profile
2,4,6,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,27,29,31.

DellEMC(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 configured, first remove the backup configuration. To
remove a switchport backup interface, enter the no switchport backup interface command.
Parameters
backup (OPTIONAL) Use this option to configure a redundant Layer 2 link without using
Spanning Tree. The keyword backup configures a backup port so that if the
primary port fails, the backup port changes to the up state. If the primary later
comes up, it becomes the backup.
interface
interface
(OPTIONAL) Enter any of the following keywords and the interface information:
● For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet then the slot/port/subport information.
● For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the
slot/port information.
port-channel (OPTIONAL) Enter the keywords port-channel if the backup port is a static or
dynamic port channel.
mode (OPTIONAL) Enter the keyword mode to set the interface mode.
private-vlan (OPTIONAL) Enter the keywords private-vlan to set the interface mode to
private VLAN mode.
host (OPTIONAL) Enter the keyword host to set the private VLAN interface to host
mode.
