S Commands
This chapter describes the Cisco NX-OS interface commands that begin with S.
shutdown
To shut down the local traffic on an interface, use the shutdown command. To return the interface to its default operational state, use the no form of this command.

Usage Guidelines
You can use this command on the following interfaces:

Note Use the no switchport command to configure an interface as a Layer 3 interface.
Examples
This example shows how to shut down, or disable, a Layer 2 interface:
switch(config)#
interface ethernet 1/10
switch(
config-if)#
shutdown
switch(
config-if)#
This example shows how to shut down a Layer 3 Ethernet subinterface:
switch(config)#
interface ethernet 1/5.1
switch(
config-subif)#
shutdown
switch(
config-subif)#
This example shows how to shut down a virtual Ethernet interface:
switch(config)#
interface vethernet 10
switch(
config-if)#
shutdown
switch(
config-if)#

speed (interface)
To configure the transmit and receive speed for an interface, use the speed command. To reset to the default speed, use the no form of this command.
speed { 10 | 100 | 1000 | 10000 | auto }

Usage Guidelines
The first 8 ports of a Cisco Nexus 6000 switch and the first 16 ports of a Cisco Nexus 6000 switch are switchable 1-Gigabit and 10-Gigabit ports. The default interface speed is 10-Gigabit. To configure these ports for 1-Gigabit Ethernet, insert a 1-Gigabit Ethernet SFP transceiver into the applicable port and then set its speed with the speed command.
The first 32 ports of a Cisco Nexus 6000 switch are switchable 1-Gigabit and 10-Gigabit ports. You can also configure them to auto-negotiate to either 1-Gigabit or 10-Gigabit. The last ports 33-48 are SFP+ ports and do not support auto negotiation.

Note On the Cisco Nexus 5000 Series switches and 6000 Series switches with 1-Gigabit Ethernet SFP transceiver, you must configure the no negotiation auto command to disable auto negotiation.
Examples
This example shows how to set the speed for a 1-Gigabit Ethernet port:
This example shows how to set the an interface port to automatically negotiate the speed:

system default switchport shutdown
To configure all Layer 2 switchports to be Layer 3 routed ports, use the system default switchport shutdown command. To reset to the default of all Layer 2 swithports, use the no form of this command.
system default switchport shutdown
no system default switchport shutdown
Syntax Description
Command Default

Usage Guidelines
When the system default switchport shutdown command is issued, any switchports (including FEX HIFs) that are not configured with no shutdown command are shut down. To avoid the shutdown, configure the switchports with no shutdown command.
Examples
This example shows how to set all ports as Layer 3 routed ports:
This example shows how to reset all ports back to Layer 2 switchports:
