Configuring The Cisco Discovery Protocol; Configuring The Cdp Characteristics - Cisco AP775A - Nexus Converged Network Switch 5010 Configuration Manual

Configuring Ethernet Interfaces
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
This command can only be applied to a physical Ethernet interface.
If the interface and transceiver speed is mismatched, the SFP validation failed message is displayed when
Note
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.
