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.
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.

PurposeCommand or Action
Enters global configuration mode.switch# configure terminal
Step 1
Enters interface configuration mode for the specified interface.
This interface must have a 1-Gigabit Ethernet SFP transceiver
inserted into it.

Step 3
For Cisco Nexus 5500 series switches, the speed argument can be
set to one of the following:
• 1000—1 Gbps
• 10000—10Gbps
• auto
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.
Note
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
