Disabling and Restarting Ethernet Interfaces

You can shut down and restart an Ethernet interface. This action disables all of the interface functions and marks the interface as being down on all monitoring displays. This information is communicated to other network servers through all dynamic routing protocols. When shut down, the interface is not included in any routing updates.

To disable an interface, perform this task:

Procedure

	Command or Action	Purpose
Step 1	switch# configure terminal	Enters configuration mode.
Step 2	switch(config)# interface type slot/port	Enters interface configuration mode for the
		specified interface.
Step 3	switch(config-if)# shutdown	Disables the interface.
Step 4	switch(config-if)# no shutdown	Restarts the interface.

The following example shows how to disable an Ethernet port:

switch# configure terminal switch(config)# interface ethernet 1/4 switch(config-if)#shutdown

The following example shows how to restart an Ethernet interface:

switch# configure terminal switch(config)# interface ethernet 1/4 switch(config-if)#no shutdown
