Cisco Systems N5KC5596TFA Configuring Interface Speed, Procedure, switch# configure terminal

Configuring Layer 2 Interfaces

Configuring Interface Speed

switch(config)# interface ethernet 1/4 switch(config-if)#udld disable

This example shows how to disable UDLD for the switch:

switch# configure terminal switch(config)# no feature udld

Configuring Interface Speed

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 If the interface and transceiver speed is mismatched, the SFP validation failed message is displayed when you enter the show interface ethernet slot/port command. For example, if you insert a 1-Gigabit SFP transceiver into a port without configuring the speed 1000 command, you will get this error. By default, all ports are 10 Gigabits.

Procedure

	Command or Action	Purpose
Step 1	switch# configure terminal	Enters global configuration mode.
Step 2	switch(config)# interface	Enters interface configuration mode for the specified interface.
	type slot/port	This interface must have a 1-Gigabit Ethernet SFP transceiver
		inserted into it.

Step 3 switch(config-if)# speed speed

Sets the speed for a physical Ethernet interface.

For Cisco Nexus 5500 series switches, the speed argument can be set to one of the following:

•1000—1 Gbps

•10000—10Gbps

•auto

Note 100 Mbps is not a supported speed for the Cisco Nexus 5596 switch or CU-96 GEM card.

For the Cisco Nexus 5596T switch, the base board ports support 1 Gbps and 10 Gbps. On the 10GBase-T ports you can also choose auto.

The following example shows how to set the speed for a 1-Gigabit Ethernet port:

switch# configure terminal switch(config)# interface ethernet 1/4 switch(config-if)#speed 1000
