Command History
Usage Guidelines The first 8 ports of a Nexus 5010 switch and the first 16 ports of a Nexus 5020 switch are switchable
1-Gigabit and 10-Gigabit ports. The default interface speed is 10-Gigabit. To configure these ports for
1-Gigabit Ethernet, insert a 1-Gigabit Ethernet SFP transceiver into the applicable port and then set its
speed with the speed command.
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 on a Cisco Nexus 5000 Series switch are 10 Gigabits.
Examples The following example shows how to to set the speed for a 1-Gigabit Ethernet port:
switch# configure terminal
switch(config)# interface ethernet 1/1
switch(config-if)# speed 1000
Related Commands
