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.
shutdown
no shutdown
Syntax Description
This command has no arguments or keywords.

This command was introduced. |
Usage Guidelines
You can use this command on the following interfaces:
- Layer 2 interface (Ethernet interface, EtherChannel interface, subinterface)
- Layer 3 interface
![]() Note | Use the no switchport command to configure an interface as a Layer 3 interface. |
- Layer 3 subinterface
- Management interface
- Virtual Ethernet 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 }
nospeed
Syntax Description
10 |
Sets the interface speed to 10 Mbps. |
100 |
Sets the interface speed to 100 Mbps. This speed is not supported on a management interface or the CU-96 CEM card. |
1000 |
Sets the interface speed to 1 Gbps. |
10000 |
Sets the interface speed to 10 Gbps. This is the default speed. This speed is not supported on a management interface. |
auto |
Specifies that the speed of the interface is auto negotiated. |
Command Default
The default speed is 10000 (10-Gigabit).
Command Modes

Usage Guidelines
The first 8 ports of a Cisco Nexus 5010 switch and the first 16 ports of a Cisco Nexus 5020 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 5596T 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:
switch#configure terminal switch(config)#interface ethernet 2/1 switch(config-if)#speed 1000
This example shows how to set the an interface port to automatically negotiate the speed:
switch#configure terminal switch(config)#interface ethernet 1/5 switch(config-if)#speed auto switch(config-if)#

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
This command has no arguments or keywords.
Command Default
The default is all ports configured as Layer 2 switchports.
Command Modes
Global configuration mode

6.0(2)N1(1) |
This command was introduced. |
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:
switch# configure terminal switch(config)# system default switchport shutdown switch(config)#
This example shows how to reset all ports back to Layer 2 switchports:
switch# configure terminal switch(config)# system default switchport shutdown switch(config)#
