Configuring Ethernet Interfaces

Enabling or Disabling CDP

	Command or Action	Purpose
		Use the	no form of the command to return to its default
		setting.
Step 5	switch(config)# [no] cdp timer	(Optional)
	seconds	Sets the transmission frequency of CDP updates in seconds.
		The range is 5 to 254; the default is 60 seconds.
		Use the	no form of the command to return to its default
		setting.

This example shows how to configure CDP characteristics:

switch# configure terminal switch(config)# cdp timer 50 switch(config)# cdp holdtime 120 switch(config)# cdp advertise v2

Enabling or Disabling CDP

You can enable or disable CDP for Ethernet interfaces. This protocol works only when you have it enabled on both interfaces on the same link.

To enable or disable CDP for 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)# cdp enable	Enables CDP for the interface.
		To work correctly, this parameter must be enabled
		for both interfaces on the same link.
Step 4	switch(config-if)# no cdp enable	Disables CDP for the interface.

The following example shows how to enable CDP for an Ethernet port:

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

This command can only be applied to a physical Ethernet interface.
